Columns and cartridges for gas, ion, HPLC, low-pressure LC, and flash chromatography; includes pre-packed and open columns, packing, guard columns and accessories, and other supplies for flash chromatography.
Use the efficient and selective Thermo Scientific™ Hypersil™ Silica LC Columns for normal phase chromatography of nonpolar and moderately polar organic compounds.
Available in a variety of stationary phases that function in normal and/or reverse phase. MilliporeSigma™ LiChroCART™ HPLC Cartridge, 250-3 comes with customized packing (please specify packing material) and is 250mmL x 3mmI.D.
ChromegaChiral™ CCJ (cellulose 4-methylbenzoate) is a new product for high resolution chiral separations based on a new halogenated carbohydrate based chiral stationary phase.
ChromegaChiral™ CCS (amylose tris [(S)-a-methylbenzylcarbamate]) permits the enantiomeric separation of 1-Indanol without the addition of DEA (Diethyl amine).
Porous-layer open-tubular (PLOT) columns are a powerful tool used in gas chromatography for analysis of fixed gases, light hydrocarbons and volatile solvents. They are mostly preferred over traditional columns.
BIOshell™ Guard Columns provide physical (filtration) and chemical protection for costly analytical columns without compromising the very high performance of BIOshell™ columns.
Ascentis™ Express Guard Columns provide physical (filtration) and chemical protection for costly analytical columns without compromising the very high performance of Ascentis™ Express columns.
Thermo Scientific™ CaptureSelect™ LambdaXP MiniChrom™ columns are designed for bench-scale resin screening, process development, and sample preparation.
Ascentis™ Express HPLC columns, through the use of Fused-Core™ particle technology, can provide you with both the high speed and high efficiencies of sub-2 μm particles while maintaining lower backpressures.
SUPELCOSIL™ LC-18-DB Supelguard™ Cartridges contain a SUPELCOSIL™ packing, in a 2 cm stainless steel body, enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits.
A typical mobile phase used with normal-phase silica columns consists of a hydrocarbon solvent such as hexane or heptane, mixed with a relatively small percentage of more polar solvent.
