As people pay more attention to the waterproof function of buildings, the amount of building waterproof material is more and more. Among them, the water-based waterproof coating as a major category in waterproof coatings, are increasingly valued by all parties. According to JC1066-2008 "Building Waterproof Coatings harmful substances in the" standard classification, the current water-based waterproof coating is divided into water-based asphalt-based waterproof coating, water-based silicone waterproofing agent, water-based anti.
Tengzhou Xiangying Analytical Technology Co., Ltd. established GC7990 gas chromatograph to determine the content of aromatic compounds in water-based waterproof coating by gas chromatography. The average recoveries were 87% ~ 99%, and the relative standard deviations were less than 8%. The average recoveries were in the range of 0.2 ~ 100 mg / L. Compared with JC 1066-2008 standard static headspace gas chromatography, this method is more sensitive and easier to operate.
随着人们对建筑物防水功能的日益重视,建筑防水材料的用量越来越大。其中,水性防水涂料作为防水涂料中的一大类,正日益受到各方重视。根据JC1066—2008《建筑防水涂料中有害物质限量》标准的分类,目前水性防水涂料主要分为水乳型沥青基防水涂料、水性有机硅防水剂、水性防。
滕州市翔鹰分析技术有限公司建立了GC7990气相色谱仪，测定水性防水涂料中芳香族化合物含量的气相色谱分析方法。采用该方法检测,各芳香族化合物浓度在0.2~100 mg/L范围内呈良好的线性关系,相关系数均大于0.998;加标平均回收率为87%~99%,相对标准偏差小于8%。与JC 1066—2008标准推荐的静态顶空气相色谱法相比,该方法灵敏度更高,操作更简便。
