活性炭充填硅膠是一種柱凈化填料,?用于微量分析多氯二苯并對二惡英(PCDDs)和多氯二苯并呋喃(PCDFs)。 微量分析要達到高精度要求,就少不了優異的樣品凈化方法。由于二惡英毒性特別高,引起社會廣泛關注,因此進行二惡英分析時,安全性必須十分可靠?;钚蕴烤?有特異吸附具有平板結構的化合物的特性,譬如二惡英?;钚蕴績艋诰聘患河悠肥潜夭豢缮俚倪^程,這點得到全球廣泛認可。然而,傳統的活性炭顆粒存 在這樣的弱點:
當顆粒較小時,滲透率較低,而顆粒較大時,在洗脫時會引起嚴重的拖尾現象。
該新型色譜柱填料,采用活性炭充填入硅膠而成,不僅具有活性炭的優良特性,而且具備很好的滲透性。
?活性炭充填硅膠?019-11941 ??[操作程序]
將玻璃棉放在色譜柱的底部,與一個旋塞相連接,加入高度約1厘米的無水硫酸鈉。然后加入1g活性炭充填硅膠,輕輕晃動柱子以使厚度均勻。在頂部再次加入另一層的無水硫酸鈉,高度約0.5厘米。(參考設備圖。)
當柱子裝填完畢,馬上用吸管將樣品(需將正己烷溶液濃縮至0.3毫升左右)慢慢滴加到無水硫酸鈉層上。然后用0.1毫升的正己烷數次洗滌管壁和無水硫酸鈉層。
靜置幾分鐘后,在色譜柱上方連接一個裝有200毫升25%[?v/v]的二氯甲烷/正己烷混合物的分液漏斗,輕輕讓混合液緩緩流下來,開始以每秒鐘1滴的速度進行洗脫。(該洗脫液不含二惡英。)
當二氯甲烷/正己烷混合液加完,繼續用200?mL甲苯以每秒1滴的流速進行洗脫。(該洗脫液含有二惡英。)
將甲苯洗脫液用減壓KD濃縮器濃縮至目標體積。

[注意事項]
多氯聯苯可以用25%二氯甲烷/正己烷完全洗脫出來,用于定量分析。
由于采用的是干燥型柱層析,在洗脫過程中,氣泡會留在柱內。不過對于回收率和重現性無不良影響。
當1,2,3,4-T4CDD?和O8CDD單組份荷載為1ng時,回收率超過90%。
T4CDD?:?Tetrachlorodibenzo-p-dioxin?四氯二苯并-對-二惡英
O8CDD?:?Octachlorodibenzo-p-dioxin?八氯二苯并-對-二惡英
