GB/T 18204.2-2025 Methods for hygiene inspection of public places Part 2: Chemical indicators specifies the determination methods for chemical pollutants in indoor air and urea in pool water in public places. This section is applicable to the determination of chemical pollutants and urea in indoor air of public places. Other indoor environments such as places and bedrooms can be referred to for implementation.
Name: Shimadzu Stainless Steel Filled Column
Specification: 3m * 4mm * 5mm
Model: GDX-102, 60-80 mesh
Maximum operating temperature: 260 ° C
Application: GB/T 18204.2-2025 Public Place Hygiene Inspection Methods Part 2: Chemical Indicators
After complete separation of carbon dioxide from other components of air in the chromatographic column, it enters the working arm of the thermal conductivity detector, causing a change in the resistance value of the arm
The change in resistance values between the reference arm and the transformer is not equal, causing the Wheatstone bridge to lose balance and produce signal output. Within the linear range, the signal size is proportional to the input
The concentration of carbon dioxide entering the detector is proportional, allowing for qualitative and quantitative measurements.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed the "GDX-102 Chromatography Column for Measuring Sanitary Carbon Dioxide in Public Places", which uses TCD detector and area external standard method for quantification, and the results are satisfactory.
