使用新型 Thermo Scientific? Dionex? IonPac? AS18-4μm 陰離子交換柱,可在色譜分析速度和分辨率之間達到*平衡。 這種高載量、高效率色譜柱可對不同樣品基質中的無機陰離子實現分離。 這是首xuan的氫氧化物選擇性色譜柱,可按照美國 EPA 方法 300.0 (A) 和 300.1,對飲料和廢水樣品中的無機陰離子進行較快速的合規監測。 與 Thermo Scientific? Dionex? IonPac? AS18-Fast 色譜柱相比,新型 Dionex IonPac AS18-4μm 陰離子交換柱可使用更小的樹脂顆粒以提高峰效率,從而縮短運行時間、提高峰積分的準確度并獲得更可靠的結果。
分離常見無機陰離子的速度zui快并且分辨率極jia
通過使用更小的樹脂顆粒和更短的柱規格,這種色譜柱可提供zui高的峰效率并能對常見無機陰離子實現*分離,因此可用于環境水體的快速分析。
分析各種基質中的常見無機陰離子和低分子量有機酸
可對常見無機陰離子進行超快速等度分離,不到 3 分鐘即可完成
按照美國 EPA 方法 300.0 (A) 所述,對飲用水中的常見陰離子進行合規監測
峰效率高且分辨率增加,從而實現更加*的積分并獲得更可靠的結果
可提供與 Dionex IonPac AS18-Fast 柱相同的選擇性,所以應用可輕松轉移至 4μm 柱
與 Dionex IonPac AS18-Fast 柱相比,運行時間縮短,但分辨率不受影響
可對各種樣品基質中的無機陰離子和低分子量酸實現分離
與有機溶劑兼容,從而可改善分析物的溶解度,改變柱選擇性,或者對色譜柱進行有效凈化
在高壓離子色譜系統中使用 4μm 柱
通過使用更小的樹脂顆粒,可達到更高的分辨率,并產生超過 3000 psi 的柱反壓。 當在 10μL/min 的標準流速下運行 Dionex IonPac AS18-4μm 毛細管柱時,一臺能夠在高達 3000 psi 的壓力下運行的離子色譜系統*夠用。 然而,為了發揮快速色譜運行的優勢,在使用高流速時,需要一臺高壓毛細管離子色譜系統,例如,Thermo Scientific? Dionex? ICS-5000+ HPIC 或 Thermo Scientific? Dionex? ICS-4000 HPIC。 Dionex IonPac AS18-4μm 微孔柱和標準孔柱正常工作時,Dionex ICS-5000+ HPIC 系統*。
使用適合您實驗室的產品規格
較短的 150mm AS18-4μm 色譜柱有助于加快運行速度,同時較小的粒徑可保持更高分辨率的分離;保護柱有 3 種規格可選:
4x150mm 標準孔柱與 4x30mm 保護柱配套使用
2x150mm 分析柱與 2x30mm 保護柱配套使用
0.4x150mm 毛細管柱與 0.4x35mm 保護柱配套使用
毛細管柱的淋洗液需要量減少,從而降低了運行成本
毛細管柱可通過節省淋洗液而顯著降低運行成本和廢液處置成本。 Dionex IonPac AS18-4μm 毛細管柱與對應的標準孔柱和微孔柱裝填同種材料,從而可提供相同的性能。 由于運行毛細管系統時的淋洗液流速僅為標準孔系統的 1%,因此運行成本得以降低。 毛細管柱可與 Thermo Scientific? Dionex? ICS-4000 和 ICS-5000+ 毛細管系統配合使用。
需要更高的分辨率還是更快的分離速度?
如果您需要對更復雜的樣品基質達到更高分辨率的分離,請選擇較長的 250mm Dionex? IonPac? AS18 氫氧化物選擇性陰離子交換柱
較短的 150mm Dionex IonPac AS18-Fast 柱與較長的 250mm 柱相比,在對相對更干凈的基質進行分析時運行速度更快、且較短色譜柱可在 3000 psi 下運行。

Attain the optimal combination of chromatographic speed and resolution using the new Thermo Scientific Dionex IonPac AS18-4μm anion-exchange column. This high-capacity, high-efficiency column provides excellent resolution of inorganic anions in diverse sample matrices. Compared to the previous Dionex IonPac AS18-Fast column, the new ion-exchange column uses smaller resin particles for more efficient separations resulting in faster run times, more accurate peak integration and more reliable results.The Dionex IonPac AS18-4μm anion-exchange column is the hydroxide-selective column of choice for compliance monitoring of inorganic anions in drinking water and wastewater samples in accordance with US EPA Methods 300.0 (A) and 300.1.
The new Dionex IonPac AS18-4μm column offers the same selectivity as the Dionex IonPac AS18-Fast column, but with the reduced particle size, this column can separate the common inorganic anions in significantly less time without loss of resolution. Applications run on the Dionex IonPac AS18-Fast column can be easily transferred to the Dionex IonPac AS18-4μm column with the benefit of reduced run time with no loss in resolution. The Dionex IonPac AS18-4μm column is available in capillary format (0.4 × 150 mm), microbore format (2 × 150 mm) and standard bore format (4 × 150 mm). The capillary format offers the advantage of reduced eluent consumption, thereby lowering operating costs.
Decrease run times, increase sample throughput without loss of resolution
Super fast isocratic separation of the common inorganic anions (less than 3 min)
Recommended hydroxide-selective column for inorganic anions in diverse sample matrices
Inorganic anion and low-molecular weight organic acids in complex sample matrices
Meets performance requirements specified in US EPA Method 300.0 (A)
The smaller resin particles used in the Dionex IonPac AS18-4μm column produce increased back pressure. When operating the Dionex IonPac AS18-4μm capillary column at the standard flow rate of 0.010 mL/min, an IC system capable of operating up to 3000 psi is sufficient. However, to take advantage of the fast runs, using elevated flow rates, a high pressure capillary IC system, such as the Thermo Scientific Dionex ICS-5000+ HPIC or the Thermo Scientific Dionex ICS-4000 HPIC is required. The Dionex ICS-5000+ HPIC systems is required for standard operation of the Dionex IonPac AS18-4μm microbore and standard bore columns.
