HPLC Guard Columns and Cartridges
Waters Corp SunFire VanGuard Cartridge, C18, 100 Å, 5 μm, 3.9 mm x 5 mm
SunFire C18 VanGuard Cartridges are designed to extend analytical column lifetime and performance by removing particulate and chemical contamination. This cartridge is installed between the injector and analytical column, ensuring compatibility and optimal protection for various HPLC, UPLC, and UHPLC systems.
- Extends analytical column lifetime and performance.
- Removes particulates and chemical contamination.
- Optimized for 4.6 mm I.D. analytical columns with 5 μm sorbent particles.
- Uses matching packing material for seamless compatibility.
- Manufactured in a cGMP, ISO 9001 certified plant with tested batches ensuring reproducible performance.
- Improves selectivity, sensitivity, and analysis speed.
- Direct-attach, single-unit design minimizes extra volume and reduces leaking.
- Cost-effective protection for 2.1 mm, 3.0 mm, 3.9 mm, and 4.6 mm I.D. analytical columns.
YMC America, Inc YMC Carotenoid grd 3um 10x4mm
YMC Carotenoid is a C30 bonded silica-based reversed phase column that is markedly more hydrophobic than classical C18 phases Even when pure organic eluents are applied many sample solutes are retained The YMC Carotenoid C30 stationary phase provides sufficient phase thickness to enhance interaction with long chain molecules therefore geometric and positional isomers of conjugated double-bonding systems are recognized and resolved It can be used to separate carotenoids in blood samples food products natural product extracts and commercial preparations In addition YMC Carotenoid operates with low aqueous or non-aqueous mobile phases that are desirable in LC/MS and prep fraction recovery

The J sphere series of columns consists of three kinds of ODS made from the same silica gel base each with a different ligand coverage The 4 um 80 silica support provides outstanding chromatographic efficiency while the high surface area material (500 m2/g) offers exceptional interaction with analytes This combination provides excellent peak symmetry across all J sphere products The variations in ligand coverage produce three columns with different hydrophobicity hydrogen bonding capacity and steric selectivity for tertiary structures Because of this J sphere can be used with confidence to identify structural differences of solutes and to improve the efficiency of separation optimization
