Ambient air volatile organic compound continuous monitoring systemAQMS-900VCM

Product Description

AQMS-900VCM ambient air VOCs online monitoring system realizes automatic online monitoring of 116 VOCs components in ambient air through dual chromatography column design and gas chromatography mass spectrometry technology. The system complies with the "Technical Requirements for Ambient Air Volatile Organic Compounds Gas Chromatography Continuous Monitoring System" and Detection Methods" (HJ1010-2018) and the Ministry of Ecology and Environment\'s 2019 Monitoring Plan for Volatile Organic Compounds in Urban Ambient Air at Prefecture Level and Above (Monitoring Letter [2019] No. 11) and other relevant standards and specifications.

Monitoring Factor

PAMS (57 types) photochemical assessment and monitoring components; TO15 (66 types) toxic and harmful components; OVOCs (12 types) aldehyde and ketone components.

Features

It uses dual channels, dual cold traps, dual chromatographic columns and dual detectors for simultaneous online analysis, and can also be used for offline analysis;

The low-temperature empty trap removes water and dehumidifies the gas entering the enrichment unit;

Low-temperature and filler-type dual-channel enrichment method. The enrichment unit adopts semiconductor electronic refrigeration technology and has a controllable heating and desorption system for rapid temperature rise and efficient desorption;

The fully automatic online dilution calibration unit can realize online dilution and mixing of multiple bottles of standard gas, realizing automatic internal standard quantification and external standard quality control;

It has China Environmental Protection Product Certification (CCEP) and Environmental Monitoring Instrument Quality Supervision and Inspection Center test report.
