Hamilton PRP-X200 ion chromatography columns are the easy way to separate ions. The PRP-X200 cation exchange HPLC columns can be used with any existing HPLC or ion chromatograph to easily determine cations in air, water and soil. PRP-X200 columns provide a number of benefits. Better than Wet Chemical Methods Anyone using wet chemical or colorimetric methods will find that ion chromatography will greatly reduce sample pretreatment and improve the accuracy and precision of results. High Sensitivity Use Hamilton ion chromatography columns to separate ions at concentrations from 20ppb to 20ppm without suppression or elaborate preconcentration techniques. Long Column Life The highly inert polymeric support resists chemical attack from organic solvents and aqueous buffers (0-100% aqueous or organic; pH 1 to 13), effectively lengthening column life. If column performance should deteriorate (peak broadening and a loss of symmetry), a regeneration protocol will usually return your chromatography to its original state. Analyze Mono or Divalent Cations PRP-X200 columns quickly and easily separate five monovalent cations in five minutes (see Application #58) or four divalent cations in four minutes (see Application #61). Unique Selectivity The highly inert poly(styrene-divinylbenzene) packing allows the use of organic modifier. By varying the concentration of methanol (see Figure 1) the resolution between cations can be altered.
