HPLC Guard Columns and Cartridges
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-Si Supelguard Cartridge Kit, 5 μm Particle Size
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.
MilliporeSigma™ Supelco™ BIOshell™ A160 Peptide CN Guard Cartridge, 4.7 μm Particle Size
BIOshell™ Guard Columns provide physical (filtration) and chemical protection for costly analytical columns without compromising the very high performance of BIOshell™ columns.
MilliporeSigma™ Supelco™ Discovery™ HS F5 Supelguard™ Cartridge, 3 μm Particle Size
The Discovery™ HS F5 bonded phase provides reversed-phase separations that are distinctly different from C18 columns. However, compounds will generally elute within the same retention time window, making most C18 methods easily transferable.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-8 Supelguard Cartridge, 5 μm Particle Size
Provides less retention of both polar and non-polar compounds than C18.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-18 Supelguard Cartridge, 5 μm Particle Size
A general purpose hydrophobic alkyl phase that is very retentive and gives good peak shape for a wide variety of compounds.
TSKgel™ G-Oligo-PW Guard Column, 13 μm Particle Size, Sold by MilliporeSigma™ Supelco™
TSKgel Guard Columns are stand-alone and do not require separate holders. For use with 7.8 mm ID TSKgel G-Oligo-PW Column, 13 μm.
TSKgel™ Octyl-80Ts Guard Cartridge, Sold by MilliporeSigma™ Supelco™
For 4.6 mm ID TSKgel Octyl-80Ts columns
TSKgel™ UP-SW2000 DC Guard Column for 4.6 mm ID Column, 2 μm Particle Size, Sold by MilliporeSigma™ Supelco™
TSKgel™ UP-SW2000 columns are designed for the analysis of small proteins, peptides and oligonucleotides. The columns are packed with 2 μm silica-based beads shielded with a hydrophilic diol-type bonded phase that prevents the silica surface from interacting with protein samples.
TSKgel™ GMHHR-H(S) HT Guard Column, 30 μm Particle Size, Sold by MilliporeSigma™ Supelco™
Guard Column for use with 7.8 mm ID TSKgel GMHHR-H(S) HT Columns. TSKgel™ HT (High Temperature) Columns are for the analysis of organic-soluble polymers at temperatures up to 140°C.
TSKgel™ SuperH Guard Column, 3 μm Particle Size, Sold by MilliporeSigma™ Supelco™
Guard Column for use with 6 mm ID TSKgel™ SuperH1000-SuperH4000 Columns, 3 μm.
MilliporeSigma™ Chromolith™ Guard Cartridge Holder
Chromolith™ guard cartridge holder with 10mmL x 4.6mmID
MilliporeSigma™ Supelco™ Ascentis™ Express OH5 Guard Cartridge, 2.7 μm Particle Size
Ascentis™ Express Guard Columns provide physical (filtration) and chemical protection for costly analytical columns without compromising the very high performance of Ascentis™ Express columns.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-Diol Supelguard Cartridge Kit, 5 μm Particle Size
LC-Diol columns can be used to separate proteins by gel filtration chromatography.
Thermo Scientific™ Shodex OHpak SB-G Guard Column
For use with HPLC columns.
