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.

The UltiMate® 3000 Offers new UHPLC capabilities in solvent delivery and sample handling with a wide range of detector options for high-throughput laboratories Designed to support very robust chromatographic runs with column

Thermo Fisher Scientific announces a new approach using high-performance anion-exchange ( HPAE) chromatography with pulsed amperometric detection (PAD) for the determination of carbohydrates in extracts from instant coffee and green coffee beans.

Thermo Fisher Scientific Inc. is pleased to announce a new application for the determination of nitrite and nitrate in milk by ion chromatography (IC) with suppressed conductivity detection using in-line sample preparation.

Thermo Fisher Scientific is pleased to announce a new Ion Chromatography (IC) method developed by Covance Laboratories Inc. for the total determination of free and total myo-inositol in foods, feeds, and infant formulas.

Hamilton Company is best known for manufacturing precision fluid measuring products, including syringes for HPLC and GC. For the last 30 years Hamilton Company has manufactured HPLC resins and columns while developing separations for customers.

Column technology has been a rich area for HPLC R&D. As reasonably expensive consumables, columns are a significant factor in LC operating costs and performance— in other words, key value drivers.

Reaction screening and purification are essential steps in small molecule pharmaceutical discovery labs. Cleaner samples for subsequent synthesis can reduce reaction by-products and facilitate the critical final purification of material for pharmaceutical profiling and toxicology studies.
