作者用丙酮处理过的Porapak Qs(乙基乙烯基苯与二乙烯基苯共聚的高分子多孔小球)柱来分离,用火焰光度检测器测定ppm级的H_2S、COS、SO_2、CH_3SH、(CH_3)_2S、(GH_3)_2S_2六种含硫气体。色谱柱的制备法如下: 取2～4克80～100目的Porapak QS干一多孔玻板漏斗中,用化学纯丙酮抽滤洗涤5～10分钟,然后抽过空气干燥,直至颗粒互不粘附时为止。将处理好的固定相装入长18时,外径1/8时,用丙酮洗过并干燥的聚四氟乙烯管中,共装约12时长,两端用玻璃毛塞好,用氦气(约55毫升/分)在240℃处理过夜即可应用。色谱条件: 柱温:程序升温,由30℃开始,进样后保持此温度1分钟,然后以40℃/分的速度升温至210℃。载气:氦,31毫升/分
The authors used acetone-treated Porapak Qs (polymeric porous beads copolymerized with vinylbenzylbenzene and divinylbenzene) columns to separate and measure the ppm levels of H 2 S, COS, SO 2, CH 3 SH, (CH 3 ) _2S, (GH_3) _2S_2 six sulfur-containing gases. Column preparation method is as follows: Take 2 to 4 grams of 80 to 100 mesh Porapak QS dry a porous glass funnel, washed with pure acetone for 5 to 10 minutes, and then air-dried until the particles do not stick to each other Attached to date. The deal with the stationary phase into the long 18, the outer diameter of 1/8, washed with acetone and dried Teflon tube, a total of about 12 hours long, both ends of the glass with a good plush, with helium (About 55 ml / min) at 240 ° C overnight. Chromatographic conditions: Column temperature: the program temperature, starting from 30 ℃, the sample was maintained at this temperature for 1 minute, and then 40 ℃ / min speed to 210 ℃. Carrier gas: helium, 31 ml / min
