Maintaining laboratory instrumentation often involves balancing in-house expertise, downtime, and the cost of outside services

A variety of different detectors exist for HPLC / UHPLC systems, and there are many other considerations when purchasing

The sample matrix can have an effect on the type of surface chemistry that is applied to the column being used

“Phenomenex offers so many sample preparation solutions that it makes sense to provide a manifold that can process them efficiently”

Technological advances have enabled us to analyze increasingly lower concentrations of chemicals

When working with highly polar compounds, HILIC tends to be the best choice for separation

Rachel Muenz talks with Terry Cain and Dr. Michael Wichman about environmental testing using HPLC and GC

Problem: The topic of technology transfer raises caution with many laboratory managers of analytical laboratories. In routine analysis laboratories, such as QA/QC, the need for continued support of established high performance liquid chromatography (HPLC) methods can significantly outweigh the potential advantages of method modernization, making it exceptionally problematic or undesirable to adopt more modern liquid chromatography (LC) assays or instrumentation such as U(H)PLC ultra-high performance LC.

High-performance liquid chromatography (HPLC) is, for many scientists, an essential chromatographic technique. HPLC systems used for the separation, identification, purification, and quantification of various chemical and biochemical solutions are composed of a pump, a sample injector, a separation column, a detection unit, and a data-processor.
