應用：空氣中苯系物測定

滕州市浩瀚色譜儀器技術服務有限公司，研發(fā)一種測定固定污染源廢氣中苯系物成分含量的方法，步驟如下：氣相色譜分離，被測樣氣導入進樣器中；氮氣經(jīng)減壓閥調(diào)整壓力后通過氣體純化器去除水分、烴與氧等雜質(zhì)；經(jīng)精細壓力調(diào)整后進入進樣器；樣氣被送色譜柱進行分離；差分光譜吸收，樣氣經(jīng)色譜柱分離后導入檢測室；使用紫外光源與紅外光源組成的聯(lián)合光源穿過檢測室，以光譜儀檢測樣氣的吸收光譜；計算得到苯系物成分含量。本發(fā)明能夠快速連續(xù)地對固定污染源廢氣中苯系物進行分析，克服了常規(guī)氣相色譜技術定性能力差；且可大大縮短苯系物的分析周期，將分析周期由常規(guī)色譜法的30分鐘以上縮短到5分鐘以內(nèi)，并可進行連續(xù)檢測與檢測因子擴展。

Application: Determination of benzene in air

Tengzhou Haohan Chromatographic Instrument Technology Service Co., Ltd. has developed a method for determining the content of benzene compounds in the exhaust gas from a fixed pollution source. The steps are as follows: gas chromatography separation, the measured sample gas is introduced into the sampler; nitrogen pressure is adjusted by the pressure reducing valve Then remove impurities such as moisture, hydrocarbons and oxygen through a gas purifier; enter the sampler after fine pressure adjustment; the sample gas is sent to the chromatographic column for separation; differential spectral absorption, the sample gas is separated into the chromatographic column and introduced into the detection chamber; used A combined light source composed of an ultraviolet light source and an infrared light source passes through the detection chamber, and the absorption spectrum of the sample gas is detected by a spectrometer; the content of the benzene series component is calculated. The invention can quickly and continuously analyze benzene compounds in the exhaust gas from a fixed pollution source, overcomes the poor qualitative ability of conventional gas chromatography technology, and can greatly shorten the analysis cycle of benzene compounds, shortening the analysis cycle from more than 30 minutes by conventional chromatography. Within 5 minutes, continuous detection and detection factor expansion can be performed.
