Hamilton Company offers one of the most comprehensive selections of chromatography columns in the industry.

• Three Particle Sizes (5, 10, and 12 to 20 µm)
• Seven Column Internal Diameters (1.0 to 50.8 mm)
• Two Column Materials (316 Stainless Steel and PEEK)
• Buffer strength 0.0 to 0.5N

Each column is manufactured under rigorous criteria and tested for resolution and retention time accuracy.

Hamilton PRP-X100 ion chromatography columns are the easy way to separate inorganic ions. You can use these columns with any existing HPLC or ion chromatograph to easily determine anions in almost any sample matrix including: air, water and soil. PRP-X100 columns provide a number of benefits. Anyone using wet chemical or colorimetric methods will find that ion chromatography greatly reduces sample pretreatment and improves the accuracy and precision of results.

Use Hamilton ion chromatography columns to separate ions at concentrations from 1 to 1000 ppm without suppression or elaborate preconcentration techniques. The highly inert polymeric support resists chemical attack from organic solvents and aqueous buffers (0 to 100% aqueous or organic; pH 1 to 13), effectively lengthening column life. If column performance should deteriorate (peak broadening and a loss of symmetry), the regeneration protocol will usually return your chromatography to its original state.

PRP-X100 columns easily separate difficult anions such as cyanide, borate and silicate at high pH (11.5). The polymeric packing is stable from pH 1 to 13, so a single column can be used for the analysis of both common and difficult anions. Single column or chemically non-suppressed ion chromatography uses ionized organic acids for eluents (mobile phases). These provide a strong counter-ion for elution and have a low equivalent conductance, allowing conductivity detection to be utilized without chemical suppression.
