Determination of moisture content in paints and varnishes - Gas chromatography method
This document describes a method for determining the moisture content in water-based coatings and their raw materials using gas chromatography. This document is applicable for the determination of moisture content in water-based coatings. The preferred working range of this testing method is the mass fraction of moisture content ranging from 15% to 90%, but this method can also be used outside of this range.
Name: Stainless Steel Filled Column
Model: Diethylbenzene Ethylethyl Vinylbenzene Polymer Porous Microspheres
Specification: 2m * 1/8, 0.18-0.25mm
Maximum operating temperature: 260 ° C
Application: GB/T 41953-2022 Determination of moisture content in paints and varnishes Gas chromatography method
The ISO 23168:2019 standard specifies a method for determining the moisture content of water-based coatings and their raw materials using gas chromatography, applicable to a detection range of 15% -90% mass fraction. This method is quantified by internal standard method and detected by thermal conductivity detector (TCD), with high-precision characteristics of repeatability coefficient of variation of 0.2-1.0% and reproducibility coefficient of variation of 0.6-3.0%.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. develops and produces "Diethylbenzene Ethylbenzene Polymer Porous Microsphere Chromatography Column" for the determination of paints and varnishes Water content, high efficiency, satisfactory results.
