比表面積510平方米/g
粒度：80-100目/60-80目，40-60目，20-40目
應(yīng)用：HJ734-2014固定污染源廢氣揮發(fā)性有機(jī)物的測定固相吸附-熱脫附／氣相色譜-質(zhì)譜法
滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，提出應(yīng)用國產(chǎn)高分子多孔微球GDX-201富集-氣相色譜法測定廢水中久效磷殘留量的分析方法。水樣經(jīng)GDX-201柱吸附富集、氯仿洗脫、濃縮,然后用氣相色譜法(OV-17固定液、FPD)測定。實(shí)驗(yàn)結(jié)果表明:GDX-201樹脂對水樣中痕量(ppb數(shù)量級)久效磷的平均回收率達(dá)94.5%,變動系數(shù)小于4%。并與溶劑萃取富集法作了對比。

GDX-201 adsorbent Details:
Stationary phase: copolymers such as styrene and divinylbenzene
Specific surface area 510 square meters / g
Particle size: 80-100 mesh / 60-80 mesh, 40-60 mesh, 20-40 mesh
Application: Determination of Volatile Organic Compounds from Fixed Sources of HJ734-2014 Solid Phase Adsorption-Thermal Desorption/Gas Chromatography-Mass Spectrometry
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. proposed an analytical method for the determination of monocrotophos residues in wastewater by using domestic polymer porous microspheres GDX-201 enrichment-gas chromatography. The water sample was adsorbed and concentrated by GDX-201 column, eluted with chloroform, concentrated, and then determined by gas chromatography (OV-17 fixative, FPD). The experimental results show that the average recovery rate of trace amount (ppb order) of monocrotophos in GDX-201 resin is 94.5%, and the coefficient of variation is less than 4%. And compared with the solvent extraction and enrichment method.
