TSKgel™ SW-Type Guard Column, 10 μm Particle Size, Sold by MilliporeSigma™ Supelco™
TSKgel™ Guard Columns are stand-alone and do not require separate holders.
MilliporeSigma™ Supelco™ Ascentis™ C18 Supelguard™ Guard Cartridge, 5 μm Particle Size
Ascentis™ C18 is an extremely stable and reliable HPLC column that gives symmetric peak shape and excellent retention even for difficult compounds.
TSKgel™ SuperSW Guard Column, 4 μm Particle Size, Sold by MilliporeSigma™ Supelco™
TSKgel Guard Columns are stand-alone and do not require separate holders. For use with 4.6 mm ID TSKgel SuperSW2000 & SuperSW3000 Columns.
Thermo Scientific™ BetaSil™ Phenyl/Hexyl Guard Cartridges
Drop-in guard cartridges offer convenience, economy and effective protection for extending column lifetime
MilliporeSigma™ Supelco™ SUPELCOGEL™ K Guard Column, 9 μm Particle Size
5 cm x 4.6 mm guard column, does not include tubing, nuts or ferrules.
MilliporeSigma™ Supelco™ Supelguard™ Guard Cartridge Holder - Stand-Alone (Swivel-type)
For use with Supelguard cartridges (2 cm L. x 2 to 4.6 mm I.D.)
TSKgel™ SuperMP(PW)-N Guard Column, 5 μm Particle Size, Sold by MilliporeSigma™ Supelco™
TSKgel™ SuperMultiporePW columns and guard columns can be used for water-soluble polymer analysis.
TSKgel™ UltraSW Aggregate Guard Column, 3 μm Particle Size, Sold by MilliporeSigma™ Supelco™
TSKgel™ UltraSW Aggregate columns have a slightly larger pore size and smaller (3 μm) particle size than the industry-leading TSKgel™ G3000SWXL (5 μm) and SuperSW3000 (4 μm) columns. These 30 cm x 7.8 mm I.D. silica-based, stainless steel columns offer reduced lot-to-lot variation, long column life, reduction of unspecified adsorption, and superior recovery of aggregates.
TSKgel™ ODS-80Ts Guard Cartridge, Sold by MilliporeSigma™ Supelco™
For TSKgel ODS-80Ts & ODS-80Ts QA columns
MilliporeSigma™ Supelco™ OPTI-GUARD™ C18, Biocompatible 1 mm Guard Column
OPTI-GUARD™ sets the standard for low-impact, easy to use pre-column protection.
MilliporeSigma™ Supelco™ Discovery™ HS F5 Supelguard™ Cartridge Kit, 5 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™ Discovery™ BIO Wide Pore C18 Supelguard™ Cartridge Kit, 5 μm Particle Size
Kits include one cartridge, a stand-alone holder, a piece of tubing, and 2 nuts and ferrules. Guard cartridges require holders that are sold separately.
