400 Passive Sampler contains a tape treated with 1-Naphthyl­isothiocyanate (NITC). Each sampler incorporates a “blank/correction” section
in addition to the active sampling section. Analysis is by high-performance
liquid chromatography with UV detection (HPLC-UV) for identifi cation of
amines that may be present in the sample. Designed for single use, the SKC
