The FGH-1-2 chromatographs have retained the main advantages of the FGH-1 model – mobility and ease of operation and maintenance. At the same time, FGH-1-2 has all the advantages of a modern multichannel chromatograph – the ability to reliably identify and accurately determine the concentrations of various pollutants of environmental objects. The additional use of automatic identification in the processing of chromatograms simultaneously through both channels makes FGH-1-2, in fact, a universal selective gas analyzer of organic substances using the chromatographic separation method. In FGH-1-2, as well as in FGH-1, all methodological problems have been solved: all measurement methods (MI) used are certified, the devices are equipped with sampling devices prescribed in MI, the devices are graded according to the required substances, independent control of the stability of calibration characteristics and measurement errors is provided.

The PA-1 single-channel portable aspirator is based on the PC-1 portable compressor. It provides air aspiration with a flow rate from 0.1 to 0.8 l/min. The aspirator is powered by an integral battery.

Ampoules with certified solutions (AS) contain solutions of a number of substances with a certified concentration. AS are designed for independent preparation by the consumer of certified combined-cycle gas mixtures while monitoring the quality of measurement results and the stability of calibration data. The use of AS for this purpose is prescribed in the methods of analysis FR.1.31.2014.17787, FR.1.31.2014.17955, FR.1.31.2015.20512, FR.1.31.2015.21296, FR.1.31.2016.23707, FR..1.31.2016.23997 and FR.1.31.2016.239967 for FGH chromatographs.
