Product Description
The increasing usage of organic chemicals causes copious amounts of volatile organic compounds (VOCs) released to the environment. Some of the VOCs showed side effects on human health, which are irritation, mutagen risk and cancer risk, etc. Benzene, toluene, ethylbenzene and xylenes (BTEX) are commonly seen VOCs. The sources of BTEX include vehicle emission, industrial plants emission, construction materials degradation, painting solvent release from new furniture and so forth. A number of analytical methods have been developed for the detection of BTEX, which usually involved the use of canister sampling and sorbent tubes. Despite the popularity of canister sampling, the use of a compact analytical device for environmental air analysis provides easier operation, faster results, and lowers the risk of sample loss and contamination. In this application note, the NovaTest P100 compact gas chromatograph (GC) with a photo ionization detector (PID) was used to analyze the BTEX in an office area. The linearity, reproducibility, detection limit and practical application performance of the NovaTest P100 compact GC were discussed.
