Investigation into the determination of arsenic by direct current plasma atomic emission spectrometer

Improvements have been made on the currently available hydride generator system manufactured by SpectraMetrics Incorporated, because the system was found to be unsatisfactory with respect to the following: 1. the drying agent, anhydrous calcium chloride, 2. the special sample tube, 3. the direction of argon flow through the Buchner funnel when it came to dealing with real sample, that is, with reference only to aqueous extracts of soil samples. Changes that were made on the system included the replacement of anhydrous calcium chloride with anhydrous calcium sulphate and the replacement of the special sample tube with a modified one made from silica. Re-directing the flow of argon through the top of the Buchner funnel appeared to make the system compatible with aqueous extracts of soil samples. The interferences from 1000 ~g/mL of nickel(II) , cobalt(II), iron(III), copper(II) have been eliminated with the aid of 1.4 M hydrochloric acid and 1% (weight/volume) L-cystine. Greater than 90% recovery of 0.3 ~g/mL arsenic signal was achieved in each case. Furthermore, 103% of arsenic signal was accomplished in the presence of 1000 ~g/mL cadmium with 5 M Hel. tVhen each of the interferents was present in solution at 1000 ppm, a recovery of 85% was achieved by using 5 M hydrochloric acid and 3% (weight/volume) L-cystine. Without L-cystine and when 1.4 M hydrochloric acid was used, the recoveries were 0% (Ni), 0% (Co), 88% (Fe), 15% (Cu), 18% (Cd). Similarly, a solution containing 1000 ppm of each interferent gave a zero percent recovery of arsenic. The reduction of trivalent and pentavalent arsenic at a pH less than one has also been investigated and shown to be quantitative if peak areas are measured. The reproducibility determination of a 0.3 Vg/mL standard arsenic solution by hydride generation shows a relative standard deviation of 3.4%. The detection limits with and without Porapak Q have been found to be 0.6 ng/mL and 1.0 ng/mL, respectively.

Letter from J.E.A. Masters to Josiah Masters, November 11, 1812

Transcription: Encampment Plattsburgh My Dear Uncle Nov. 11th 1812 We are making every possible preparation to invade Canada. I have no doubt but we march in six days. From the best information I can get it is not contemplated to attack the Isle aux Noix – We shall take into the field 2500 infantry between 3 & 4 hundred cavalry 25 light artillery & 150 artillerists; of the malitia I have no accurate knowledge there is more than 1000 of them, the number of regular troops is mentioned you may rely on as being nearly correct I cannot state to a man as I have not had an opportunity of being the consolidated returns of the different corps. It is said that a [corps formed?] of volunteers are to join us from Vermont. I think it doubtful I believe that we shall have no great difficulty in going to Montreal as to the ultimate policy of the [act it is?] not my duty to judge. Confidential our troops are raw particularly in loading and firing they are much deficient. The 6th and 15th will be able to act with some considerable ... of precision and accuracy the remaining infantry—badly disciplined. Should any thing [occur?] with me my fate be unfortunate the [little?] property willed me by my grandfather will secure you the amount I owe you. General Dearborn I understand is at Burlington on his way here. Some of the prisoners that were taken at Queenstown have [arrived?] at Montreal probably. [Ensign Rich?] is among them. Several officers here became acquainted with him soon after he received his [two illegible words] & speak highly of him. [Always?] affectionately yours J. E. A. Masters P.S.

Daniel D. Tompkins letter to General Dearborn, June 28, 1812.

Transcript [original spelling and grammar retained]: Albany June 28 1812 Sir Your letter of the 23d has been received. I had anticipated your request by ordering the detachment from Washington, Essex, Clinton and Franklin Counties into service and have fixed the days and places of their Rendezvous. Upon application to the quarter master General I find there are but 139 tents & 60 camp kettles at this place & even those I take by a kind of stealth. The Deputy Quarter Master General declines giving an order for their delivery until he shall have a written order from the Quarter Master General, and the latter is willing I Shall take them but will not give the Deputy a written order for that purpose. Under Such circumstances I shall avail myself of the rule of Possession and by virtue of the Eleven Points of Law Send them tomorrow morning without a written order from anyone. You may remember that when you were Secretary of the war department I invited you to forward and deposit in our Frontier Arsenals, arms ammunition and camp equipage free of expense to be ready in case of war and the same invitation to the war department has been repeated some time, Since The United States have now from 5 to 600 regular troops at Plattsburgh, Rome, Canandaigua & c, where those arsenals are, and yet those recruits are now and must be for weeks to come unarmed and unequipped in every respect although within musket Shot of arsenals. The recruits at Plattsburgh are within 50 miles of two tribes of Canadian Indians. In case of an attack upon the Frontiers that portion of the United States army would be as inefficient and unable to defend the inhabitants or themselves even. The Militia Detachments on the Western Frontiers received the news of war with [cherafulness] and determined courage, and I am happy to find they are united late brothers, highly improved in Discipline & ready to devote themselves to any Service or danger which the good of the Country may require. But they are in barracks from which they cannot move a days march for the want of tents and other equipage, and they are in Separate and Independent Detachments without a General Officer to command them or combine their exertions for the accomplishment of any desirable and important object. The only officer of the United States here who can do anything is the Quarter Master General and he has not a tent Camp Kettle or Knapsack in this arsenal except what I have concluded to send off tomorrow morning as above mentioned to furnish men As to Cannon Muskets and Ammunition. I can find now one here who will exercise any authority over them or deliver a Single article upon my requisition. Neither can I find any Officer of the army who feel himself authorized to exercise any authority or do any act which will aid me in the all important object of protecting the Inhabitants of an extended Frontier exposed to the Cruelties of Savages and the depredations of the enemy. If I must rely upon the Militia Solely for Such protection I entreat you to give orders to your Officers to furnish upon my orders, for the use of the Militia Detachments , all needful weapons and articles with which the United States are Supplied and of which we are destitute . You may rely upon all the assistance which my talents, influence or authority can furnish in the active prosecution of the first & necessary way which has been declared by the Constituted Authorities of our beloved Country. I am, Sir, respectfully Your ob. Servt. Daniel D. Tompkins

Charles Larned letter, April 3, 1813.

Charles Larned (1791-1834) was a lawyer and American military officer who served during the War of 1812. He was the son of Simon Larned (1753-1817), who served as a captain in the Revolutionary War and was a member of the United States Congress from Massachusetts from 1804-1805. Charles studied law in the office of Henry Clay in Kentucky, and was dining with a group of prominent citizens when word was received that General William Henry Harrison could soon be overpowered by General Henry Proctor. Colonel Owen, a member of the group, organized a regiment to reinforce Harrison’s troops. Larned became a member and subsequently survived the River Raisin Massacre and was later present at the Battle of the Thames. He was also part of a group of men who learned of General William Hull’s plan to surrender Detroit to the British and planned to overtake him should this occur. However, the plan failed, Hull did surrender and the men became prisoners of the British. After the war, Larned became a lawyer, and served as Attorney General of Michigan Territory during the Black Hawk War. During the cholera epidemic of 1834, he worked tirelessly to assist others, but was stricken with the disease and died. Letter Transcription: Pittsfield, April 8, 1813 I think that by this time my dear Charles you will allow I have some reason to give you a gentle reprimand for breach of duty—but I will not censure you upon suspicion maybe you have substantial reasons—at any rate one cannot very graciously reproach the other for negligence I for one am healthy as ham & that we have so seldom exchanged letters during your absence & on my honor promise to be a better girl in future—but the truth is my Dear Charles I am secretary for the Family—Mama you know never writes & James but seldom & they are all dispersed in different directions, consequently I have many calls upon my time—this to be sure is a pleasant duty & I urge it only as a slight palliation for my remissness if you should consider it as such—now I have finished my preface—I will try to be more interesting & doubtless I succeed. Our dear Father we hope & trust is now in Green Bush, where he will probably remain a month perhaps & from thence he expects to go to Sacket’s harbor—at which place you know our troops are fast collecting-- We shall hope to see him either here or there before he goes. Brother George I believe is [still] at Plattsburgh but expects soon to be removed to some other military part perhaps with Papa (I hope so at least). We have just got letters from Brothers Sylvester & Joseph at Middlebury—they are in good health. Mama has for some weeks been afflicted with an inflammation in her eyes but seems now to be convalescing. Sister Martha has been somewhat unwell for a few weeks but is now tolerably recovered. James & myself are both in our usual good health & at this time seated by the same stand, one reading, the other writing. Thus my Dear Charles have I given you an abstract history of our Family—but here indeed is a wonderful omission; not a word about Miss Harriet Hunt, who in truth ought to have been noted first but the last she’s not the least in my memory. She is much grown since you saw her, but does not speak as fluently as we could wish—a few word she can say. Probably before this you have been informed of the great loss your friend Sherrill has sustained in the death of his mother—also of the revolution that has taken place in Hackbridge as it respects the religion & morality of the place that more than one hundred on the plain have become religious converts & c—indeed I am at a loss what to say that will afford your pleasure—a narrative at this time must be gloomy indeed. The distressing situation of our country at this time would make almost any recital melancholy. The prevailing epidemic has swept off many of your acquaintance no doubt. Mrs. Dewey of Williamstown, the sister of Mrs. Danforth, has left a Husband, Children & many Friends sincerely to lament her loss—some few have died in our village, but we have escaped astonishingly –it has raged in every town about us--If we are unwilling to acknowledge a God in his mercies. I fear she shall be compelled to do it in the awfulness of his judgments.--------I am much [pleased] with our new neighbors the Parsons Wife & a Miss Woodward her cousin is a fine girl, I think, Mrs. Allen has not a handsome face but something in her manner that interests one her person I think the handsomest I ever saw & the Parson seems well pleased with his selection—Mrs. Ripley is with them this winter & will probably remain thro the summer—Her husband at [Sackett’s Harbor] little or no alteration is apparent since her marriage—she seems as gay & fond of company as ever.-------Mrs. [McKnight] it is expected will commence housekeeping in about three weeks in the house formerly occupied by Mr…. [Report] says that Mr. Goodman & Clarissa Weller are soon to be married & many other things that I must omit to mention for Mama wants a… PS reserved--now my Dear Charles remember you are considerably… & I am confident you have as much leisure as I have –… be ceremonious but write whenever I find time not & I beg… the same – I tell James I shall not send his love for he must write himself. I shall anxiously expect you to write & do not disappoint your affectionate, sister--H One word my Dear Charles from your affectionate Mother who longs to see Her Dear son Charles—but being deprived of that rich blessing at present—begs Him so to conduct that she may hope for it ere long—do you search the Scriptures and keep the Sabbath holy unto the Lord—and all the sacred Commandments of God—it is my ardent desire…He would protect, support and provide for your soul and body and believe me your affectionate friend and Mother. R Larned.
