Air

CVR Labs is qualified and has the necessary equipment to conduct indoor air quality analyses and microbiology air analyses. We test air for Environmental, Microbiology and Industrial Hygiene analyses, depending on the need of our clients. Our sampling media ranges from cassettes, swabs, and even summa canisters, to name a few. CVR Labs can supply the needed sampling or media kit as necessary to perform the analyses. We also have a certified team that conducts sampling at the request of the client.

Indoor Air Quality Analyses:

Formaldehyde
Volatile Organic compounds (VOC) down to ppb levels
Pesticides in Air
Airborne Mold and Bacteria
Tape and Bulk Sample Analysis for Mold

*Volatile Organic Compounds by TO-15*	Air samples are collected in a Summa Canister or a Helium Diffusion Sampler. VOCs are concentrated on a solid sorbent trap, refocused on a second trap, separated on a GC column, and passed on an MS detector for identification and quantification.
*Volatile Organic Compounds by TO-17*	*Ambient air is drawn through a multi-bed sorbent tube where VOCs are trapped. At A & B Labs, the tube is thermally desorbed and analyzed by GC/MS.*
*Volatile Organic Compounds by TO-15-HDS*	The HDS Personal Monitor simplifies the monitoring of chemicals in the workplace. A breakthrough new technology based on helium diffusion yields a sampler that is small, light weight, cost-effective, universal, and defensible.Above all, the HDS Personal Monitor delivers highly reproducible results unaffected by factors that create errors in other diffusive samplers such as matrix concentrations, varying humidities, and fluctuating face velocities. An HDS sample is collected based upon the higher diffusion rate of helium relative to air, creating a vacuum that pulls air in as helium escapes. A surrogate recovery compound is added to every HDS Personal Monitor to substantiate the collection of a proper sample in the field as well as to prove effective recovery during laboratory analysis. A simpler way to collect canister samples is now available
