粗苯中三苯測定經(jīng)濟型氣相色譜儀 粗苯即焦油苯(crude coking)是煤熱解生產(chǎn)焦炭過程中產(chǎn)生的副產(chǎn)物之一,主要組分為芳香烴類物質(zhì),并伴有含硫化合物,成分其復(fù)雜,很難準確地對各組分進行定量識別。在粗苯中,三苯(即苯、甲苯、二甲苯)的含量是評價粗苯優(yōu)劣的主要指標。
傳統(tǒng)粗苯中三苯測定,采用毛細管色譜柱,氫火焰檢測器,操作復(fù)雜,重現(xiàn)性查,不利于在中小企業(yè)及粗苯貿(mào)易公司推廣,使用受限。
滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司,與時俱進,研發(fā)出《粗苯中三苯測定經(jīng)濟型氣相色譜儀儀》,滿足了不同行業(yè)的需求。

An economical gas chromatograph for the determination of triphenyl in crude benzene
Crude benzene, or tar benzene (crude coking), is one of the by-products produced in the process of coke production by coal pyrolysis. The main components are aromatic hydrocarbons and are accompanied by sulfur-containing compounds. The components are quantitatively identified. In crude benzene, the content of triphenyl (ie benzene, toluene, xylene) is the main indicator for evaluating the quality of crude benzene.
The traditional determination of triphenyl in crude benzene uses capillary chromatographic column and hydrogen flame detector, which is complicated in operation and reproducible, which is not conducive to promotion in small and medium-sized enterprises and crude benzene trading companies, and its use is limited.
Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. keeps pace with the times and has developed the "Economical Gas Chromatograph for the Determination of Triphenyl in Crude Benzene" to meet the needs of different industries.
