On line monitoring of volatile organic compounds from fixed pollution sources using gas chromatography

Ontech610On line monitoring of volatile organic compounds from fixed pollution sources using gas chromatographyIt is a highly integrated non methane total hydrocarbon analyzer that can continuously monitor fixed pollution sources and total hydrocarbons, methane, non methane total hydrocarbons, and benzene derivatives in the air online. Ontech610 adopts quantitative ring injection, a 12 position multi way valve, a dedicated chromatographic column combination, and central cutting and backflushing technology; The design is completely in accordance with the national standard HJ604-2017, and it is an online analyzer that can monitor total hydrocarbons, non methane total hydrocarbons, and methane in fixed pollution source exhaust gas. It can also be customized according to user needs, and the sample port can be expanded to 8 and has obtained a certificate. It can also be upgraded to low-temperature concentration adsorption sampling.

Scope of application:

Ontech610On line monitoring of volatile organic compounds from fixed pollution sources using gas chromatographyCan be used for online monitoring of total hydrocarbons, non methane total hydrocarbons, and methane in any fixed pollution source exhaust gas.

Product Features:

Continuous online monitoring of pollution sourcesAs shown in Figures ① and ②, two quantitative rings and a 12 position multi way valve are used for injection analysis through the quantitative ring. The injection volume of the quantitative ring can be customized to analyze high and low concentration samples, and low-temperature concentration enrichment and ultra-low concentration injection analysis can also be achieved.

technologically advancedAs shown in Figure 3, Ontech610 adopts a dedicated chromatographic column combination and blowback technology, designed in full accordance with the national standard HJ604-2017. It is a very advanced online analyzer for monitoring total hydrocarbons, non methane total hydrocarbons, and methane in fixed pollution source exhaust gas

highly integratedAs shown in Figures ④ and ⑤, it also integrates an injection system and gas chromatography, with a small volume.

structural designInnovative structural design, no cold spots throughout the process, and customizable sample ports for expansion according to user needs.

unattendedThe system can automatically analyze standard samples, run calibration curves, save and export data, and save the heavy workload of operation and maintenance personnel.

Easy to operate- Summarize the experience of previous system design, design from the user's perspective, make the system operation and analysis software simple and easy to use, suitable for operation and maintenance personnel to quickly get started, and collect all the functions of the chromatography workstation for sample reprocessing, making the application flexible, convenient and fast.

Over limit warningThe compound over limit warning function can transmit the over limit situation to mobile devices in real time, shortening the emergency response time.
