Airzone offers CALA accredited VOC analysis with SUMMA canisters. SUMMAs have been the industry standard for low level VOC air sampling for many years. Our method is TO15 equivalent and is suitable for a variety of cases where either regulatory mandated methods are required, or when low level characterization of compounds cannot be obtained by using another method i.e., low molecular weight VOCs not captured by sorbent tubes. Moreover, in situations where odor or chemical exposure events are transient, SUMMA canisters are able to collect quick grab samples in problematic areas. Lastly, this method offers us the ability to offer open characterization services for low level VOCs, and scan for unknown chemicals. Have a look at our standard analysis suite, note that other compounds can be added to the list.
