固定污染源排氣中乙醛的測(cè)定玻璃柱 詳細(xì)信息:
名稱:填充玻璃柱
規(guī)格:2m*3mm(內(nèi)徑)
型號(hào):20%PEG-20M/GCS880 AW DMCS(80-100目)
應(yīng)用: HJ/T 35-1999 固定污染源排氣中乙醛的測(cè)定 氣相色譜法
1 適用范圍
1.1 本標(biāo)準(zhǔn)適用于固定污染源有組織排放和無(wú)組織排放的乙醛測(cè)定。
1.2 當(dāng)采樣體積為100L,進(jìn)樣體積為1μL時(shí),乙醛的檢出限為4×10-2mg/m3,乙醛的定量測(cè)定濃度范圍為0.14mg/m3-30mg/m3。
2 方法原理
用亞硫酸氫鈉溶液采樣,乙醛與亞硫酸氫鈉發(fā)生親核加成反應(yīng),在中性溶液中生成穩(wěn)定的a-羥基磺酸鹽,然后在稀堿溶液中共熱釋放出乙醛,經(jīng)色譜柱分離,用氫火焰離子化檢測(cè)器測(cè)定,以標(biāo)準(zhǔn)樣品色譜峰的保留時(shí)間定性,峰高定量。
