Easy Ion Determination
Hamilton PRP-X110 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-X110 columns provide a number of benefits
Better than Wet Chemical Methods
Anyone using wet chemical or colorimetric methods will find that ion chromatography greatly reduces sample pretreatment and improves the accuracy and precision of results.
High Sensitivity
For High Sensitivity, use the Hamilton PRP-X110 ion chromatography columns to separate ions at concentrations from less than 20 ppb to 20 ppm. PRP-X110 Ion Chromatography columns have similar selectivity to RP-X100 columns but provide lower method detection limits. Detection limits for three detection methods are listed below:
1. Separation of Anions at 20 ppb on 150 x 4.1 mm PRP-X110
2. Separation of Anions at 0.5 ppm on 150 x 2.1 mm PRP-X110
3. Separation of Anions at 1 ppm on 150 x 4.1 mm PRP-X110
The ion capacity of the ion-exchanger is determined by the number of functional groups per unit weight of the stationary phase. The most commonly used unit is milliequivalents of charge per gram of dry packing, or milliequivalents per ml of wet packing. In the second case it is customary to state the type of counter-ion present in the stationary phase, since it affects the degree of swelling of the packing and hence its volume. The ion-exchange capacity of a stationary phase plays a significant role in determining the concentrations of competing ions used in the mobile phase for elution. Higher capacity stationary phases generally require the use of more concentrated mobile phases, which are problematic when high performance ion-chromatography is concerned, due to the use of conductometric detectors, which cannot function well with high salt concentrations. Typical ion-exchange capacity in IC is 10-100 mequiv/g.
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), the regeneration protocol will usually return your chromatography to its original state.
Use for EPA 300.0
PRP-X110 columns can be used in the suppressed conductivity mode for determination of inorganic anions as required in EPA 300.0 Part A (bromide, chloride, fluoride, nitrate, nitrite, phosphate, sulfate) see
Application #356.
Easy Determination of Fluoride
Whether you use bicarbonate or p-Hydroxybenzoic acid mobile phases you can easily quantitate fluoride. See Applications #357 and #358 for examples.
What's the difference between PRP-X110 and PRP-X110S Columns?
PRP-X110 columns are equilibrated with a 2 mM p-hydroxybenzoic acid pH 9.3 mobile phase and are ready for use with conductivity or indirect UV detection methods.
PRP-X110S columns are equilibrated with a 1. 7 mM sodium bicarbonate, 1.8 mM sodium carbonate, 0.1 mM sodium thiocyanate mobile phase and are ready for use with suppressed conductivity detection methods.
