The 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.

Supplier: Merck

These columns are situated between the traditional non bonded cyanosilicone phases SP-2330 and SP-2340 in polarity. The high polarity of this phase allows the separation of geometric (cis/trans) fatty acid methyl ester isomers as a group.

Supplier: Merck

These columns with excellent retention and resolution of polar compounds are less hydrophobic than C18 columns.

Supplier: Merck

Made of highly porous monolithic rods of silica with a revolutionary bimodal pore structure, therefore, high separation efficiencies are reached under low back pressures. These columns have long lifetimes within pH range of 2,5 to 7,5, high matrix tolerance and speed of analysis. Technical information.

The selectivity offered by ZIC®-HILIC is suitable for a wide variety of molecules containing hydrophilic or ionisable functional groups. This includes compounds such as carbohydrates, metabolites, acids and bases, organic and inorganic ions, metal complexes, amino acids, peptides, protein digests, plant and cell extracts, plus much more. Such compounds are normally characterised by a small or negative LogP value and have poor retention on reversed-phase columns.

Supplier: Merck

Supplier: Merck

Purospher® STAR RP-8 endcapped, like Purospher® STAR RP-18 endcapped, is based on high purity silica and has an almost complete surface coverage. Thus, Purospher® STAR RP-8 provides excellent peak symmetry for acidic, basic and even chelating compounds, highest column efficiency in terms of the number of theoretical plates, and exceptional stability from pH 1,5 to 10,5. In addition, they are ideal for a wide range of applications. As the sorbent is less hydrophobic than Purospher® STAR RP-18 endcapped, analytes will typically elute faster on the C8 phase. Purospher® STAR RP-8 endcapped provides enhanced selectivity for positional isomers and symmetrical peak shapes for strongly basic and less hydrophobic compounds.

Supplier: Merck

Available with optimised 2 μm particulate silica, these UHPLC columns, based on Purospher® STAR RP-18 endcapped, are ideal for ultra-fast applications, where resolution, sensitivity and sample throughput are crucial. They are the first choice for high throughput screening and QC analyses, process monitoring, method development and LC-MS applications. Due to its balanced selectivity, Purospher® STAR RP-18 endcapped UHPLC columns cover almost all demanding separations with tailing-free chromatograms. Purospher® STAR RP-18 endcapped 3 μm columns are recommended for difficult samples where clogging and back pressure present an issue.
