利用 Thermo Scientific Dionex Io習在nPac AS11-HC 毛細管分科林析和保護柱分解複雜基質中數量衆多的無機陰離子和有機酸陰離子。 複雜的樣坐廠(yàng)品基質(例如化工廢水洗脫液和發(fā)酵肉湯溶液)含有各種(z煙哥hǒng)無機陰離子和有機酸。 利用高容量的 Di什去onex IonPac AS11-HC 柱,您可新森以注入更高濃度的樣(yàng)品,而不會見動(huì)出現柱過(guò)載或峰如動擴寬。
Dionex IonPac AS11-HC 柱音秒專門爲利用氫氧化梯度在單次運行中分解分析物而設計。 答有這(zhè)款高容量的柱爲改善一價羧酸(包括奎尼酸鹽、乳酸鹽、乙酸鹽、丙哥慢酸鹽、甲酸鹽和丁酸鹽)的分離而設計。
高容量,更高分辨率
需要更長(cháng)的保留時(shí)間,但是分辨率更高
促進(jìn)良好(hǎo)表征的樣(yàng)品黃女中有機酸和陰離子的快速分析
特别适合分解複雜樣(yàng)品基質或未鐘跳表征樣(yàng)品中的有機酸和陰離子
建議用于一價和二價有機酸
更低的洗脫液要求,降低運行成(chéng)本
全新的 Dionex IonPac AS11-HC C就子apillary 柱使用與同等标準孔和微孔版本相同的填道和料(提供與 4 mm 和 2 mm 柱相同的性能(néng)),但僅使西笑用 1% 的洗脫液流速,幫助降低運行成(ch請睡éng)本。
對(duì)于高離子強度樣(yà服他ng)品中的有機酸,使用 Th低匠ermo Scientific? Dionex? IonPa視資c? ICE-AS1 或 ICE-AS6 柱。
用途和特點:
IonPac AS11-HC要金 陰離子交換分離柱用 NaOH或KOH做 淋 洗 液 ,看音用 于 無 機 陰 離 子 和老科有機酸陰離子的快速分離,包括:無機陰離子;一價,二價,三價脂肪酸;Kreb’s去內循環酸;高電荷陰離子,如多聚磷酸鹽,多聚硫酸鹽,多聚碳酸鹽;疏水性離子聽近如I-,SCN-,S2O32-和ClO4-;核苷酸。有機溶劑可匹配性方便陰離子兵服交換選擇性的控制,以及複雜基質分析後(hòu)的清洗。可用IonPac AG1拍商1作濃縮柱。作梯度淋洗時(shí)也人,在泵和進(jìn)樣(yàng村鐘)閥之間連接一支陰離子捕獲柱以除去來自淋洗液中污染弟玩的陰離子。用EG40淋洗液發(fā能報)生器。IonPac AS11和高容量柱AS11-HC均有4玩和mm标準孔柱和2-mm微孔柱。
