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.
Analytical teams that support biologic drug development require rapid, sensitive, and precise methods for protein quantitation from cell culture, fermentations broths, or purification intermediates.
SurePac Oligo RP MDI is a robust reversed-phase column designed for oligonucleotide analysis by HPLC and LC-MS. It delivers high recovery, bioinert column hardware, and reproducible separations, enabling reliable profiling of oligonucleotides of any size.
TSKgel™ G-Oligo-PW is designed for high resolution separations of aqueous nonionic and cationic oligomers, and oligosaccharides such as hydrolyzed cyclodextrins. Because of the presence of cationic groups on the gel matrix, this column is not suited for separating anionic polymers. The PEG and PEO calibration curve is identical to that of G2500PWxl.
This non-polar, general purpose column primarily provides a boiling point elution order with a slight increase in selectivity, especially for aromatic compounds.
Thermo Scientific™ POROS™ CaptureSelect™ hGH HPLC columns incorporate the advantages of high-speed POROS chromatography resins with the unique selectivity of CaptureSelect ligands.
Specifically designed for purification of oligonucleotides, RNA, and DNA fragments (up to 500 mer). TSKgel OligoDNA RP can provide excellent separations of samples with very similar sequences.
TSKgel™ Butyl-NPR columns are not as hydrophobic, i.e., less retentive, than Phenyl-5PW and Ether-5PW HIC columns. They are the best choice for high speed separations and provide excellent recovery even for more hydrophobic proteins.
TSKgel™ Phenyl-5PW RP columns are filled with 10 micron porous polymethacrylate particles, the surface of which is covered with a high density of phenyl groups that causes proteins to be retained in a low salt buffer mobile phase and requiring a solvent gradient for their elution, as is the protocol in reversed phase chromatography.
TSKgel Butyl-NPR is the best choice for high speed separations with excellent recovery even for more hydrophobic samples. The non-porous resin requires lower sample loading and leads to faster analysis time because the binding kinetics occur only on the bead′s surface.
Use for high-pressure applications, such as the Vanquish UHPLC system's extended pressure capabilities, for greater power of separation, speed, and throughput.
