Dionex IonPac AS15 陰離子交換柱 057594
利用 Thermo Scientific? Dionex? IonPac? AS15 毛細管分析和保護柱測定高純度水基質(zhì)中無機陰離子和低分子量有機酸的痕量濃度。 該款色譜柱專為分析半導體和發(fā)電行業(yè)使用的高純度水基質(zhì)中的痕量陰離子而設計，靈敏度高，對較早洗脫的陰離子（如氟化物、乙醇酸鹽、乙酸鹽和甲酸鹽）可實現(xiàn)的分辨率。 柱選擇性在 30°C 操作溫度下達到*，適合與大定量環(huán)進樣配合使用。
描述
提供多種規(guī)格
Dionex IonPac AS15-5μm (3x150mm) 柱可實現(xiàn)高效快速分析 (15 分鐘)
Dionex IonPac AS15-9μm（2x250mm、4x250mm 和 0.4x250mm）柱適用于較高容量的應用
Dionex IonPac AS15 毛細管柱 (0.4x250mm) 性能與標準孔柱相同，但只需 1% 的淋洗液流速，從而幫助降低運行成本
為實現(xiàn)*性能，請

For Trace-Level Concentrations of Inorganic Anions and Low-Molecular Weight Organic Acids
The IonPac? AS15 column was designed specifically for analysis of trace anions in high-purity water matrices, for the semiconductor and power generation industries. Its high capacity and selectivity enable the determination of trace-level concentrations of inorganic anions and low-molecular-weight organic acids in high-purity water matrices. The new IonPac AS15 Capillary Column is packed with the same material as the equivalent standard bore version (providing the same performance as a 4 mm column) but requires only 1/100th the eluent flow rate. The capillary format provides the advantage of significantly reduced eluent consumption, which helps reduce operating costs.
AS15-5μm (3 × 150 mm) column for high efficiency, fast analysis (15 min)
AS15-9μm (2 × 250, 4 × 250 mm, and 0.4 × 250 mm) columns for higher-capacity applications
Column selectivity optimized for 30 °C operating temperature
Superior resolution of early-eluting anions (fluoride, glycolate, acetate, and formate)
This column is ideal for use with large-loop injections. Use the AC15 concentration column for ultratrace (ppt) analyses. Use with eluent generation for simplified eluent preparation. Use the Anion Self-Regenerating Suppressor? (ASRS? 300) or the Anion Capillary Electrolytic Suppressor (ACES? 300) with the AS15 column for eluent suppression.
