Polymer Laboratories (PL), now a part of Varian, Inc., offers the most complete range of rigid polymeric media for HPLC applications. PL's polymeric particles are available with a range of orthogonal chemistries, reversed phase and weak and strong anion and cation exchange functionalities for 2D HPLC as well as conventional analytical separations. A range of high performance packed columns is available for capillary/micro/analytical HPLC in sizes from 300m ID up to 7.5mm ID for applications in the areas of proteomics, combinatorial chemistry, high throughput screening and ADME. The range of pore sizes, 100Å, 300Å, 1000Å and 4000Å provides the optimum pore size for the analysis of small molecules through to the largest biological macromolecules. In addition, PL manufactures columns with monodisperse sulfonated packings for carbohydrate, organic acid and alcohol analysis by ligand exchange.
PL manufactures the leading range of evaporative light scattering detectors (ELSD) for HPLC, µbore, SFC, GPC and HTGPC. ELS detectors detect all compounds less volatile than the mobile phase and, with the unique advantage of low temperature operation, the benefits of PL's ELS detectors compared to UV or RI now apply to an even wider range of HPLC applications.
PL is a world leader in the design, build, service and support of evaporative light scattering detectors, with almost 20 years' experience in this field.
