PTM300 Portable Gas Chromatograph
Product Introduction
A portable GC with a sensitive PID and controlled column temperature for ppb-level detection without sample preconcentration. It measures benzene, toluene, ethylbenzene, xylenes, trichloroethylene and tetrachloroethylene in indoor and workplace air. The internal 100 mL carrier-gas cylinder supports more than 12 hours of gas supply. Purified air can also serve as the carrier gas.
FEATURES
APPLICATIONS
Industrial safety: occupational-risk assessment in petrochemical and chemical plants. Environmental emergencies: rapid screening at pollution incidents. Indoor and vehicle air: BTEX in enclosed spaces. Research: VOC migration and transformation in soil and water.
