Overview
The dynamic dilution instrument (also known as the dynamic gas analyzer) is an analytical instrument used in the fields of environmental science and resource science and technology. It is mainly used to dilute high concentration standard gases into low concentration gases required for laboratory gas chromatography calibration. It can achieve the preparation of standard gases with concentrations ranging from ppm to ppb or ppt by precisely controlling the mixing ratio of standard gases and dilution gases
Product Details
The system should be able to comply with the "Determination of 65 volatile organic compounds in ambient air by tank sampling/gas chromatography-mass spectrometry" (HJ759-2023), "Determination of 8 sulfur-containing organic compounds including methyl mercaptan in fixed source exhaust gas by gas bag sampling pre concentration/gas chromatography-mass spectrometry" (HJ1078-2019), Monitoring Plan for Air Volatile Organic Compounds and (EPA) TO-15A The requirements for sample analysis pre-treatment and standard sample preparation in the document can be well applied to the detection of volatile organic compounds in the atmosphere.
