Introduction

The SKC Nitrous Oxide Passive Sampler is a small sampler that provides accurate

and reliable sampling of nitrous oxide in the 50 to 450 ppm range (12.75 to 890 ppm-

hours dose range). The samplers are packaged as empty sampler housings that the

user ﬁ lls with cleaned/purged Molecular Sieve 5A sorbent supplied in glass vials

with PTFE-lined caps. This method of packaging maintains low sorbent background.

Samples are thermally desorbed and analyzed by gas chromatography with electron

capture detector.
