High-sensitivity analysis allows a wide variety of measurement modes, including MRM, scan, combination scan/MRM, and neutral loss scan

UltiMate 3000 XRS UHPLC System Offers new UHPLC capabilities in solvent delivery and sample handling with a wide range of detector options for high-throughput laboratories.

HPLC is, for many scientists, an essential apparatus for the separation, identification, purification and quantification of various compounds.

In HPLC columns, reverse-phase and normal-phase chromatography separation methods are based on polarity. Reverse phase columns separate analytes based on their hydrophobicity, with the more hydrophobic compounds being retained longer on the column.

Chromatographers who learned their craft 20 years ago may not have been familiar with autosamplers then, but today nearly every high performance liquid chromatography (HPLC) instrument includes an autosampler as standard equipment.

Gas chromatography (GC) was at one time commonly called “GLC,” where the “L” stands for liquid. Inside GC columns are particles of a ceramic or inert material coated with an extremely viscous liquid stationary phase that interacts with the analyte.

Today, newer purification technologies have proven able to compete with long-established distillation. Following a brief review of these purification technologies are data for performances of a single and double distillation system, and the Millipore Elix UV system.
