EXPEC 3200-700 is a highly integrated, GC-PID-based portable GC with a built-in pre-concentration module and a low heat capacity programmed temperature column (equipped with the pro version), which realizes the detection of benzene and toluene in public places and indoor air, rapid detection of xylene, and rapid qualitative and quantitative analysis of organic matter in ambient air, soil, and water for public health emergencies, and the detection limit can reach ppb level. The method fully complies with the standard requirements of "GB/T 18883-2022 Indoor Air Quality Standard".
Portable GC-PID method that fully meets the standard requirements. Deeply cultivated in the VOCs monitoring industry, with rich field application experience to ensure stable equipment performance.
Built-in pre-concentration module, the detection limit is as low as 1ppb; The microplate flow path control technology has low dead volume, and the whole process of sample gas path is heated and inertized to reduce the adsorption loss of high boiling substances and make the measurement more accurate.
Integrating sampling system, sample processing system, gas system, separation system, detection system, temperature control system, data processing system, power supply system and data processing system; The weight is less than 10kg, and it can be carried on one or both shoulders, and one person can complete the on-site inspection task.
700P Pro is equipped with a programmable temperature-lowering low-heat-capacity chromatographic column, and the analysis time of benzene, toluene, and xylene is ≤3min; 700P Pro has the ability of real-time counting and rapid screening to help quickly find high-value areas; A variety of accessories are available to meet the needs of VOCs detection in water, air and soil.
