The product complies with HJ 732-2014 Sampling of Volatile Organic Compounds from Fixed Pollution Sources - Gas Bag Method; HJ 38-2017 Determination of Total Hydrocarbons, Methane and Non-Methane Total Hydrocarbons from Fixed Pollution Sources - Gas Chromatography Method.
Application Scope
Applicable to passive (gas bag method) manual collection of non-methane total hydrocarbons and some VOCs in exhaust from fixed pollution sources, and also applicable to passive (gas bag method) sampling of other gaseous pollutants from pollution sources. Printing function.
Instrument Features
•The instrument is the first in the industry to integrate temperature control and sampling components in a humanized one-piece design, all integrated on the sampling tube handle, making instrument operation faster and more convenient;
•Uses imported PTFE three-way valve and adjustable speed brushless high-pressure vacuum pump, sampling flow six-level adjustable;
•Efficient heating device, maximum controllable temperature up to 180℃, meeting pollution source VOCs sampling conditions;
•Inlet gas path and vacuum box passive pumping gas path integrated design, no need for manual repeated switching of gas paths during sampling operation;
•Instrument control part separated from vacuum box, can meet users' independent selection of different capacity gas bags (VOCs collection requires fluoropolymer film gas bags such as PVF) and suitable capacity vacuum box;
•Users can choose 1L to 12L multiple models of vacuum boxes (standard 10L vacuum box, suitable for gas bags within 5L);
•The instrument monitors vacuum box pressure in real time, can automatically stop sampling, or manually stop sampling;
•After sampling, vacuum box negative pressure automatically released, or manually released, enabling quick sample removal;
•Instrument sampling and cleaning automatically switch, no manual intervention required, minimizing staff labor intensity.
