Grab & Critical Orice Sampling
There are several ways to fill a MicroValve canister or Bottle-Vac depending on the sampling requirements. Here’s a brief overview:
Grab Sampling
MiniCan or Bottle-Vac samplers are filled within 0.1 - 0.3 minutes, by either removing the valve (around the valve sampling), or using an unrestricted sampler.
Restricted Critical Orice Sampling
Sample is collected through the valve using a filtered orice restricted sampler.Fill rates are constant until the canister reaches one-half atmosphere.
Time Integrated Sampling
TWA sampling is used for slow filling of canisters to determine average target compound concentrations. Fill times are 10–50 times longer than with critical orifice restricted samplers. Use the CS1200E and the PN: MQT-400 adapter for Micro-QT Valve Samplers.
