Why canisters? When using charcoal tubes, passive monitoring badges or other techniques to sample air, consider the advantages that canister air sampling can offer: Ensure more stable and reliable data. Detect lower to high concentrations (LOQ). No need for a pump due to vacuum pressure. Flexible sampling periods, including grab sampling and time-integrated options ranging from minutes to a week. Retesting possible (depending on volume). Large list of components possible. Extended holding times.
