HPLC Guard Columns and Cartridges
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-NH2-NP Supelguard Cartridge, 5 μm Particle Size
SUPELCOSIL™ LC-NH2 Supelguard™ Cartridges contain a SUPELCOSIL™ packing, in a 2 cm stainless steel body, enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits (2 μm porosity).
TSKgel™ GMHHR-H (20) and (30) HT2 Guard Column, 30 μm Particle Size, Sold by MilliporeSigma™ Supelco™
The TSKgel™ mixed bed columns are packed with particles of different pore sizes that are blended to provide an extended linear calibration curve. Mixed bed columns are used when a broad range of polymer molar masses is expected in the sample.
Thermo Scientific™ Hypersil™ BDS C18 Javelin Guard Columns
Offer convenient, easy-to-use protection for analytical HPLC columns
MilliporeSigma™ Supelco™ Astec™ Cellulose DMP Chiral HPLC Guard Cartridge, 5 μm Particle Size
Guard cartridges to protect Astec™ Cellulose DMP columns.
Ascentis™ Express 160 Å Phenyl-Hexyl, 2.7 μm HPLC Column, Sold by MilliporeSigma™ Supelco™
Target analytes include electron-poor molecules, aromatic or unsaturated compounds (ketones, nitriles, alkenes), as well as peptides and polypeptides < 20 kDa.
TSKgel™ UP-SW2000 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.
Thermo Scientific™ BetaBasic Phenyl Guard Cartridges
Guard columns provide convenient, easy-to-use protection for analytical HPLC columns
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-ABZ Supelguard Cartridge Kit, 5 μm Particle Size
SUPELCOSIL™ LC-ABZ phase has a unique deactivation technology which provides excellent reversed-phase performance for basic compounds, as well as those that are acidic, polar neutral, and non-polar.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-8-DB Supelguard Cartridge, 5 μm Particle Size
SUPELCOSIL™ LC-DB phases are specially deactivated for basic compounds. These columns provide less retention, better peak shape, and higher efficiency for organic bases than can be obtained on conventional reversed-phase columns.
Thermo Scientific™ UHPLC Filters
Protects columns without compromising performance.
MilliporeSigma™ Supelco™ Astec™ Cellulose DMP Chiral HPLC Guard Kit, 5 μm Particle Size
Guard cartridges to protect Astec™ Cellulose DMP columns
Thermo Scientific™ BetaBasic™ 8 Javelin Guard Columns
A good first choice for compounds typically considered difficult to analyze
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-8 Supelguard Cartridge, 5 μm Particle Size
Provides less retention of both polar and non-polar compounds than C18.
