【摘要】：建立一套氣相色譜檢測(cè)方法,分析條件如下:不銹鋼色譜柱(6 m×3 mm);固定液為鄰苯二甲酸二壬酯和β-β′-氧二丙腈的混合物,混合比例為1∶1,涂布濃度為20%,載體為6201紅色擔(dān)體,載體顆粒的粒徑為1.65~1.98 mm;載氣為氫氣,流量40m L/min,柱溫35℃,氣化溫度100℃,熱導(dǎo)池檢測(cè)器溫度110℃。檢測(cè)方法的相對(duì)標(biāo)準(zhǔn)偏差在0.39%~2.78%之間,加標(biāo)回收率在94.1%~104.3%之間,操作簡潔、分析快速、結(jié)果準(zhǔn)確。
[Abstract]:A set of gas chromatographic method was established. The analytical conditions were as follows: stainless steel column was 6 m 脳 3 mm, the stationary solution was a mixture of dinonyl phthalate and 尾-尾 -dioxy dipropionitrile, the mixture ratio was 1: 1, the coating concentration was 20 and the carrier was 6201 red support.The particle size of the carrier is 1.65 ~ 1.98 mm, the carrier gas is hydrogen, the flow rate is 40 mL / min, the column temperature is 35 鈩，
