141 Results for: "GC Columns"

Supplier: MERCK, S.A. DE C.V. SV

LiChrospher® CN has polar and hydrophobic properties, thus can be used as less polar alternative to LiChrospher® Si 60 in normal phase applications or as less hydrophobic alternative to LiChrospher® RP-8 in reversed phase applications.

Supplier: MICROSOLV TECH CORP

These useful HPLC columns have a silica hydride surface similar to other TYPE-C™ phases but the uniqueness of Diamond Hydride™ is that they have a very small amount of carbon on the surface that adjusts the hydrophobicity to a small but important level. This is an excellent choice for small, polar compounds by LCMS or HPLC.

YMC-Triart C18, 1.9 µm is a novel, organic/inorganic hybrid silica particle derivatized with C18 (L1 USP designation).

Supplier: MERCK, S.A. DE C.V. SV

Cartridges are filled with reliable, versatile, traditionally produced spherical silica carrier materials.

Supplier: YMC AMERICA, INC

YMC-Pack Pro C18 RS offers excellent peak shape for basic compounds due to extensive endcapping of the stationary phase, and also exhibits high recognition of stereoselectivity because of high-carbon polymeric-type bonding.

Supplier: RESTEK CORP

Our C8 is a conventional monomeric octylsilane column offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape over a traditional C18 phase.

Supplier: MERCK, S.A. DE C.V. SV

These cartridges are ideal for highly efficient HPLC analysis of complex mixtures where high peak capacity is required, because the guaranteed number of theoretical plates for Superspher® cartridges is <100.000 N/m.

Supplier: MERCK, S.A. DE C.V. SV

Columns are for use with basic, neutral, metal, chelating, or any other sample format, and are ideal for the separation of difficult hydrophobic samples. Purospher™ STAR columns are designed to provide optimum results even when loaded with large or small sample volumes and are also available in a narrow-bore format (1mm). The wide pH range provides the required pH stability for 99% of the common analysis applications. These columns provide the power to separate even the most difficult of compound mixtures. With up to 150,000 plates per meter for the 3µm particle size and 100,000 plates per meter for the 5µm particle size, Purospher™ STAR columns ensure good baseline separations. Special derivatization and endcapping processes ensure long-term chemical stability, excellent retention stability, and long column lifetime. All Purospher™ STAR columns are guaranteed to provide absolutely reproducible results.
