Dionex IonPac AS15 陰離子交換柱 057594 測定高純度水基質中無機陰離子和低分子量有機酸的痕量濃度。
利用 Thermo Scientific? Dionex? IonPac? AS15 毛細管分析和保護柱測定高純度水基質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電行業使用的高純度水基質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*，適合與大定量環進樣配合使用。
提供多種規格
Dionex IonPac AS15-5μm (3x150mm) 柱可實現高效快速分析 (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*性能，請
使用 Thermo Scientific? Dionex? IonPac? AC15 濃縮柱進行超痕量（萬億分之一）分析
使用 Dionex 淋洗液發生器進行簡單的淋洗液制備
將 Thermo Scientific? Dionex? 陰離子自再生抑制器 (ASRS? 300) 或 Thermo Scientific? Dionex? 陰離子毛細管電解抑制器 (ACES? 300) 與 Dionex IonPac AS15 柱聯用，以實現淋洗液抑制

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.
