Determinación de compuestos orgánicos potencialmente alérgenos en equipos textiles de protección individual (EPIs) mediante analisis directo por pirólisis acoplado a cromatografía de gases espectrometría de masas (Py-GC/MS).

Nota de aplicación instrumental desarrollada en el Servicio Central de Análisis de Bizkaia (SCAB)

Nowadays different cases of allergy in different clothes have been observed due to organic components used in industrial preparation of garments. Mainly, these compounds are usually dyes although it is also possible to find other related compounds of the industrial processes such as preservatives. An analytical methodology to detect the presence 15 of organic compounds with potentially allergenic properties in Personal Protective Equipment (PPE) has been developed. Samples previously homogenized in a cryogenic mill, were introduced into a Py-GC/MS. With this methodology, the presence of a potential allergen (benzyl benzoate) in some of the new clothes analyzed could be detected and, simultaneously, the presence of dyes would be also discarded. Moreover, the disappearance of this compound in the contaminated PPE was confirmed after a washing treatment.
