14 New EtG/EtS Column Solves Matrix Interference Problems
Mass Flow Meters Mass Flow Controllers Mass Flow Manifolds
A Raptor EtG/EtS column is your solution. Typical methods for EtG and EtS analysis have several limitations: poor resolution from matrix components, long run times that limit sample throughput, and short column lifetimes.
Unmatched Dynamic Range 20 sccm 20,000 sccm
Restek has developed a new Raptor EtG/EtS column that consistently retains and resolves EtG and EtS from matrix interferences, providing accurate, reliable results injection after injection. Reliable performance and long column lifetime make this column ideal for alcohol consumption monitoring by high-throughput labs. Paired with Restek reference standards and its fast, 4-minute, dilute-and-shoot LC-MS/MS method, the Raptor EtG/EtS column allows you to analyse EtG/EtS samples with confidence.
Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or ‘core-shell’ particles) with the resolution of highly selective USLC technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times without expensive UHPLC instrumentation.

SLE Plate Provides High Recovery Extraction of Analytes from Biological Fluids
Porvair Sciences announces a new easy-to-use 96-well Supported Liquid Extraction (SLE) microplate designed for high recovery extraction of analytes from biological fluids.
Using the Porvair SLE plate high analyte recovery, free of proteins and phospholipids, is routinely obtainable without the need for offline steps such as protein precipitation.
Supported Liquid Extraction is a separation technique similar to traditional liquid-liquid extraction (LLE) which uses water and an immiscible solvent to extract analytes. In SLE, the aqueous sample is immobilised on an inert support such as diatomaceous earth, and the organic phase flows through the support, eliminating problems such as emulsion formation.
Based upon the automation compatible Microlute 96-well format, the Porvair SLE plate provides fast, reproducible and economical sample clean-up when used with a simple vacuum manifold or positive pressure device. Proprietary frit technology in the plate ensures that samples will not drip or breakthrough until pressure or vacuum are applied, allowing longer dwell time in the plate wells.
The large pore size and high pore volume of the diatomaceous earth inert support, combined with a wide pH working range (1-13), allows the separation of viscous aqueous solutions such as blood, plasma and serum which may contain phospholipids and proteins. Demonstrating high recovery rates for small polar and non-polar compounds the Porvair SLE plate provides the perfect sample clean-up device for physiological fluids prior to analysis by LC/MS. The Porvair SLE plate has also been shown to be particularly helpful to environmental, food and textile labs involved in sample clean-up prior to analysis.

Columns for Fast Lab Analysis and Purification
Kromasil, a brand of silica-based particles for chromatography by AkzoNobel, has been expanded with new pre-packed columns for lab testing. The new Kromasil EternityXT C8, similar to the already available surface modifications EternityXT C18 and PhenylHexyl can be used under a wider range of pH than regular silica equivalents. The product was already available in bulk for large-scale applications and is now introduced in new convenient pre-packed columns suitable for small-scale testing and analysis. The columns are available in three particle sizes: 1.8 µm for UHPLC applications, 2.5 µm for both UHPLC and HPLC applications and 5 µm for HPLC and semi-preparative chromatography.
The Kromasil EternityXT columns are based on patented technology, resulting from more than 25 years of development after the launch of the original Kromasil silica line, which is used in amongst others the pharmaceutical and food and beverage industries as well as for environmental testing.
