Polymer Laboratories has launched a range of capillary and micro chromatography columns for small scale chromatography packed with the highest performance polymeric materials available
Chemically stable polymeric particles are ideal for small scale chromatography and in particular LC-MS applications, as they are chemically stable and do not leach either soluble or particulate species.
They can therefore be used for the most demanding high sensitivity separations, for applications including proteomics, combinatorial chemistry, high throughput screening and ADME. Capillary columns with a 300um internal diameter are best suited to sample sizes in the range pg to ng, and are used with flow rates around 4ul/min.
Micro columns with an internal diameter of 1.0mm are designed for sample sizes in the range ng to mg, and typically operate at flow rates in the range 40ul/min.
Capillary and micro chromatography columns from Polymer Laboratories are available packed with reversed phase (PLRP-S) and both strong and weak cation (PL-SCX, PL-WCX) and anion (PL-Sax, PL-Wax) wide pore exchange media.
A gigaporous 4000A range of reversed phase and ion exchange materials is available where ultra high speed analyses are required.
A small pore, high capacity, 100A PLRP-S material is also included in the range for small molecule or peptide analysis.
