Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. established a simple and accurate gas chromatographic method to detect the water content in water-based interior wall coatings by improving the extraction reagent, optimizing the relative correction factor, ultrasonic extraction time, sample injection volume and other influencing factors. The optimal analysis conditions of the experimental method are: 0.2 g of sample is added with 2 mL of isopropanol (0.1 g/mL) DMF internal standard solution, ultrasonic extraction at 23 ℃ for 10 minutes, centrifugation at 23 ℃ for 5 minutes, and 1.0 μ L supernatant gas chromatographic analysis. The internal standard method is used to calculate the moisture content in the interior wall coating by using the calibration curve. The equation of the moisture content calibration curve is Y=2.43X+0.049, and the correlation coefficient R2=0.999 8. The relative standard deviation (RSD) is 0.22% ～ 0.68% (n=6), and the recovery is 98% ～ 108% The experimental method improves the extraction efficiency, shortens the analysis time, reduces the experimental error, and has good reproducibility and accuracy
