Liquid – Liquid Chromatography (LLC) techniques, such as Centrifugal Partition Chromatography and Counter Current Chromatography, utilise the same ancillary pumps, injectors, detectors, fraction collectors, control and data systems as SLC. The CPC or CCC instrument will be designed to retain one solven...
Choosing to run small-scale models prior to scaling up experimental procedures for producing and purifying viral vectors can provide answers and projections for future work. Some chromatography labs have taken to using mechanistic modeling for optimization and increased process understanding to determine ho...
I know that my answers and suggestions will directly affect their success. Ultimately, the #1 goal is to help our customers with their challenges." John R. Palmer, B.S., Chemistry Author, Development and Validation of Analytical Methods in Pharmaceutical and Biomedical Research Chromatography ...
Ascentis® Express AQ-C18 is a high-speed, high-performance liquid chromatography column based on the Fused-Core® particle design. The particle provides a thin porous shell of high-purity silica surrounding a solid silica core. This particle design exhibits very high column efficiency due to ...
However, profiles of flavan-3-ols and proanthocyanidins in these two hybrids have not been characterized. Herein, we report the use of high-performance liquid chromatography-quadrupole, time-of-flight, tandem mass spectrometry (HPLC-qTOF-MS/MS) to characterize these two groups of metabolites in ...
In addition, both the alcohol addicts and the average alcohol users answered 10 questions of the self-report version of the Alcohol Use Disorders Identification Test (AUDIT) [18] and their answers were scored. Since EtG levels in hair are known not to be significantly influenced by gender, ...
