浩瀚色譜（山東）應用技術開發(fā)有限公司根據《檢測和校準實驗室能力的通用要求》中的線性擬合法,對固定污染源廢氣中苯系物的測定。以甲苯為代表物質,進行不確定度評價。方法參照GB/T22554-2010(基于標準樣品的線性校準)的技術規(guī)范要求,繪制甲苯的標準曲線。根據其標準曲線的數(shù)據,用統(tǒng)計學方法,獲得本次固定污染源廢氣中甲苯的測定,其擴展不確定度為±5.524 mg/m3。
國標中采用的毛細管柱，浩瀚色譜（山東）應用技術開發(fā)有限公司，與時俱進，研發(fā)專用的HH-Benzene series-III苯系物專用柱可替代毛細管，固定污染源廢氣中苯、甲苯、乙苯、鄰二甲苯、間二甲苯、對二甲苯、異丙苯和苯乙烯8組分分離良好，結果準確可靠。
規(guī)格：3m*1/8
型號：HH-Benzene series-III
應用：HJ 1261—2022固定污染源廢氣 苯系物的測定 氣袋采樣/直接進樣-氣相色譜法
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. determined the benzene series in the waste gas of fixed pollution sources according to the linear fitting method in the General Requirements for the Capability of Detection and Calibration Laboratories. Take toluene as the representative material to evaluate the uncertainty. Methods The standard curve of toluene was drawn according to the technical specifications of GB/T22554-2010 (Linear calibration based on standard samples). According to the data of its standard curve, the determination of toluene in waste gas from fixed pollution sources was obtained by statistical method, with an expanded uncertainty of ± 5.524 mg/m3.
The capillary column used in the national standard, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd., has developed a special HH-Benzene series-III benzene series column to replace the capillary column, and the eight components of benzene, toluene, ethylbenzene, o-xylene, m-xylene, p-xylene, cumene and styrene in the waste gas from the fixed pollution source are well separated, with accurate and reliable results.
Specification: 3m * 1/8
Model: HH-Benzene series-III
Application: HJ 1261-2022 Determination of benzene homologues in waste gas from fixed pollution sources Air bag sampling/direct injection - gas chromatography
