Study on Testing Water Content of Interior Wall Coating by Gas Chromatograph

Gas chromatography (GC) is a separation technique. In practical work, the samples to be analyzed are often multi-component mixtures in complex matrices. For samples containing unknown components, they must be separated first, and then the relevant components can be further analyzed. For the test of the water content of the interior wall paint, we can use the GC9800 online gas chromatograph. In addition, electronic balance, micro sampler, small glass bottle with rubber stopper, glass syringe, pipette, capillary column and other equipment are needed.
