Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. will connect the atmospheric constant flow sampler, membrane box pressure gauge, and soap film flowmeter in a certain order, fix the sampling tube, fill it with the specified mass of adsorbent, and apply appropriate pressure until the displayed values of the membrane box pressure gauge and soap film flowmeter meet the requirements of GB 50325-2010. When the flow rate is 0.5L/min, the resistance should be between 5 and 10kPa to prevent penetration during the sampling process. After laboratory testing and practical engineering testing, all indicators meet the requirements of GB 50325-2010, which greatly improves the accuracy of TVOC detection in indoor environments of civil construction projects.
