The SKC Nitrous Oxide (N2O) Passive Sampler provides accurate
and reliable sampling of nitrous oxide in the 50 to 450 ppm range (12.75
to 890 ppm-hours dose range) for up to 8 hours. The sampler
clips easily to employee clothing in the breathing zone and does not
interfere with activities. A secondary diffusion barrier ensures the
proper sampling rate of 0.81 ml/min. The sampler features a built-in
vial adapter for direct sorbent transfer from vial to sampler and sampler
to vial. Samples are thermally desorbed and analyzed by gas chromatography
with electron capture detector (GC-ECD). Designed primarily for the
healthcare industry, these samplers may be used in other industries,
such as the food industry, for nitrous oxide exposure sampling.
The SKC Nitrous Oxide Passive Sampler makes sampling easy!
- Fill the sampler housing with sorbent supplied in vial.
- Install secondary diffusion barrier and clip sampler on employee clothing in the breathing zone.
- When sampling is complete, unclip sampler, package it, and ship it to a laboratory for analysis.
About Nitrous Oxide
Nitrous Oxide (N2O) or laughing gas is a colorless gas
with a sweetish odor and taste. It is very stable and inert chemically
at room temperatures.
Nitrous oxide is not classifiable as a human carcinogen; however, it
is a narcotic at high concentrations. Nitrous oxide is used as an anesthetic
in dentistry and surgery, as a propellant gas in food aerosols such
as whipped cream, and as an inert gas to displace bacteria-inducing
oxygen when filling packages of chips and other similar snack foods.
Nitrous oxide can also be used for leak detection and in motor racing
as an oxidizer to increase the power output of engines.
