Whatman SPE固相萃取柱上海摩速公司代理的詳細(xì)介紹
固相萃取柱
有8種反向試劑
也運(yùn)用Florisil、二氧化硅和離子交換
樣品濃縮柱
可選用多種吸附劑重量/體積
具有樣品純化的濾膜配套
與大多數(shù)真空復(fù)式接頭配套
Whatman固相提取柱用于HPLC、GC、TLC或其它技術(shù)分析的樣品的制備。其特點(diǎn)是外殼為聚丙烯材料，內(nèi)部可選用各種硅基填料，硅基填為有8種可選擇的反相化學(xué)試劑，普遍用于農(nóng)藥濾渣的Florisil
TM填料，二氧化硅和離子交換。樣品干燥裝置含無水硫酸鈉。與Whatman
PartisilTM HPL填料一樣，所有包裝都是高質(zhì)量的。
為進(jìn)一步的純化樣品，有些固相提取柱配有0.2μm聚丙烯濾膜，這種濾膜與大多數(shù)有機(jī)溶劑配套，且過濾后絕無溶出物。
Whatman固相提取柱有兩種類型，一為容500mg吸附劑的柱子與Luer
Lok針筒配套使用；另為有各種重量/體積比的吸附劑可供選用的柱體。
柱體與大多數(shù)多歧式接頭的真空固相萃取儀或自動(dòng)化系統(tǒng)配套使用，也可單獨(dú)使用。
樣品濃縮柱
該柱呈圓筒形，可直接與Lure
Lok注射器相連接。用注射器推動(dòng)，使樣品經(jīng)過濃縮柱，收集于小瓶，并去除水分。該柱含無水硫酸鈉，能結(jié)合樣品中的水分，形成NA2SO
4＊10G2O,若需再干燥，可將二個(gè)或多個(gè)柱連接起來使用。
Whatman SPE devices have silica-based chemistries and are
