阴离子浓缩色谱柱 
  IonPac® 阴离子浓缩色谱柱主要用于高纯水浓缩后分析。一定体积水样浓缩后，各组分浓度增大，检测限降低2-5个数量级。

  IonPac anion concentrator columns are designed primarily for high-purity water analysis. The  concentrator retains ions from a measured volume of aqueous sample matrix, concentrating the
analyte species and lowering detection limits by 2–5 orders of magnitude

AMC-1
  The AMC-1 is a very low void volume microconcentrator column designed for the concentration of inorganic anions and low-molecular-weight organic anions from ultrapure water. A unique, solvent-compatible resin technology ensures a low sulfate background and ruggedness during the concentration step. The AMC-1 can be loaded with either a loop or sample loading pump. The low void volume (approximately 15 μL) ensures accurate determination of early-eluting anions such as fluoride,
glycolate, acetate, and formate. The AMC-1 can be used with carbonate/bicarbonate or borate eluents.

Cryptand C1
  The IonPac Cryptand C1 Concentrator Column is recommended for the analysis of trace perchlorate in drinking water. This adjustable-capacity column contains a macroporous, 17.5 μm resin grafted with the macrocyclic 2,2,2 cryptand compound. The column’s functional capacity depends on eluent concentration and the type of cation bound within the cryptand molecule.
• Approximately 30 μeq/col of cryptand capacity available for use
• Capacity adjustable from fixed amount to zero by via eluent concentration or cation type
  The adjustable capacity makes the Cryptand C1 a powerful tool for determining trace perchlorate in drinking water and high ionic strength water. Methods using the C1 can quantify 140 ng/L of perchlorate in a background of total dissolved solids with concentrations as high as 3000 mg/L. The Cryptand C1 is specified for sample preconcentration in US EPA Method 314.1.

IonPac TBC-1
  The IonPac TBC-1 Trace Borate Concentrator Column is optimized for trace analysis of borate. The TBC-1 has a low void volume and is packed with a unique resin surface grafted with highly selective polyol groups. The TBC-1 is coupled to a specially designed ICE-Borate column for the determination of borate at ng/L (ppt) concentrations. Mannitol eluent quantitatively elutes borate from the TBC-1
concentrator column.
