Title (EN) PROTECTIVE BARRIER AGAINST CONTAMINATION FROM SAMPLE PREPARATION AND EXTRACTION DEVICES
(FR) BARRIÈRE DE PROTECTION CONTRE UNE CONTAMINATION PROVENANT DE DISPOSITIFS DE PRÉPARATION ET D'EXTRACTION D'ÉCHANTILLONS
Abstract:
(EN) We present an improved plastic device useful for the transfer and storage of solid SPE sorbents and liquid sample solutions, where the sample solutions are free from contaminants originating from within the plastic device. The plastic devices include the underlying plastic device coated with a single layer of parylene. Parylene has been demonstrated to be a sufficient barrier without the need for additional organic or inorganic layers, where the contaminants of interest originate from within the underlying plastic device. Solid sorbents and liquid solvents and sample solutions have been demonstrated to be adequately protected from contaminants originating from the underlying plastic device under standard conditions described in SPE analytical methods.
(FR) L'invention concerne un dispositif en plastique, tel qu'un corps de seringue, un tube, une cartouche, un disque filtrant, une tubulure, un réservoir à solvant, un raccord, une valve, un élément en verre fritté ou un contenant, pour transférer ou stocker des solides et des liquides utilisés dans des procédés de préparation et d'extraction d'échantillons (SPE), une couche de revêtement barrière de parylène étant appliquée sur la surface du dispositif en plastique pour empêcher que les solides et les liquides transférés ou stockés par le dispositif en plastique selon l'invention soient contaminés par des contaminants provenant du plastique du dispositif.
