Supplier: Merck

Dual layer SPE tube that contains Na2SO4 (upper layer) and Florisil (magnesium silicate; lower layer) separated and packed with PTFE frits (glass tubes) or PE frits (PP tubes).

Supplier: Resonac

RSpak DS columns are suitable for reversed-phase analysis of highly hydrophilic substances, which cannot be retained well by ODS columns.

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.

Supplier: Merck

These LpDNPH cartridges are suitable for sampling carbonyls in ambient, indoor, and industrial atmospheres. The derivatives are eluted from the cartridge in acetonitrile and are analysed by HPLC.

Supplier: Merck

These columns have been designed following the high demand for suitable analytical methods for process monitoring and quality control of wide pore biomolecules. Accurate analysis of proteins, antibodies and large peptides requires columns with good permeability, along with better mass transfer and selectivity. In order for size exclusion not to influence the separation, the pore size should be approximately ten times larger than the molecule being analysed.

Supplier: Avantor

Avantor® ACE® Glycan is a high performance stationary phase designed for the analysis of 2-aminobenzamide labelled glycans by hydrophilic interaction liquid chromatography (HILIC). These ultra-inert, high efficiency columns provide excellent column lifetime and reproducibility with buffers and mobile phases typically utilised for glycan analysis. Two particle sizes are available to enable both high resolution and rapid separations on HPLC and UHPLC instrumentation.
