赛默飞Thermo IonPac AS18 Hydroxide-Selective Anion-Exchange Column离子色谱IC柱

For Determination of Inorganic Anions and Low-Molecular-Weight Organic Acids

The IonPac^®AS18 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 newIonPac AS18-Fast columns offer the same selectivity as the AS18 analytical scale columns, but with a reduced length of 150 mm, these columns can separate the common inorganic anions in significantly less time. The capillary format offers the advantage of reduced eluent consumption, thereby lowering operating costs.

• Fast separation of the common inorganic anions (4 min) using the AS18-Fast columns

• Recommended hydroxide-selective column for inorganic anions in diverse sample matrices

• Isocratic separation of common inorganic anions in 9 minutes

• Inorganic anion and low-molecular weight organic acids in complex sample matrices

• Superior retention and quantification of fluoride, acetate, and formate

• Meets performance requirements specified in US EPA Method 300.0 (A)

The IonPac AS18 column can determine inorganic anions and low-molecular-weight organic acids in a variety of sample matrices. This column has excellent retention of fluoride from the water dip. It is approved for compliance monitoring of inorganic anions in drinking water and wastewater samples in accordance with US EPA Methods 300.0 and 300.1. The AS18 column is now available in capillary format providing the advantage of reduced eluent consumption, thereby lowering operating costs.
