Dionex IonPac AS25 陰離子交換柱 076014
使用 Thermo Scientific? Dionex? IonPac? AS25 色譜柱可以在 25 分鐘內(nèi)分離多價(jià)和可極化陰離子而無需有機(jī)溶劑。 此款高容量氫氧化物選擇性陰離子交換柱是檢測復(fù)雜基質(zhì)中硫形態(tài)的理想選擇，如食品和飲料樣品以及來源于工業(yè)、化學(xué)和石化行業(yè)排放的污水。 此款色譜柱可以快速、簡單的分離可極化陰離子，包括硫代硫酸鹽、碘化物、硫氰酸鹽和高氯酸鹽。 為了獲得可極化陰離子的*峰形，使用 Thermo Scientific? Dionex? IonPac? AS16 色譜柱或 Thermo Scientific? Dionex? IonPac AS20 色譜柱。

High-Capacity Column Optimized for Determination of M*lent Anions and Polarizable Anions including Sulfur Species
The Thermo Scientific Dionex IonPac? AS25 column is ideally suited for the analysis of m*lent anions and polarizable anions (iodide and perchlorate) including sulfur species (sulfite, sulfate, thiosulfate and thiocyanate) in complex sample matrices. The Dionex IonPac AS25 column simplifies the determination of polarizable anions, including thiosulfate, iodide, thiocyanate, and perchlorate by using an isocratic hydroxide eluent with no solvent required for the separation. However, for the best peak shape of polarizable anions, use the Thermo Scientific Dionex IonPac AS16 column or the Thermo Scientific Dionex IonPac AS20 column.
Separate hydrophobic anions (iodide, thiocyanate, and thiosulfate) in approximately 25 min without the use of solvent
Ideal for polyvalent anions, including polysulfates, polyphosphates and polycarboxylates
Analyze complex matrices including wastewater effluents from chemical industries, foods and beverages
Ultralow hydrophobicity allows fast analysis of polarizable anions
The Dionex IonPac AS25 is a high-capacity, hydroxide-selective column for the determination of m*lent anions and polarizable anions including sulfur species in complex sample matrices including wastewater effluents, scrubber solutions and food and beverage samples can be easily separated on the Dionex IonPac AS25 without the use of solvent. The Dionex IonPac AS25 column is available in 0.4 × 250 mm , 2 × 250 mm, 4 × 250 mm formats supporting flow rates from 0.010 to 3 mL/min.
