LCGC TV: Giorgia Greco on Reversed-Phase LC Coupled to HILIC
HILIC was introduced more than 50 years ago but has attracted more attention recently. Giorgia Greco from the Technische Universität Munchen in Germany discusses the different options available for combining HILIC to reversed-phase LC, and how HILIC can be hyphenated with atmospheric pressure chemical ionization MS. |

| Quality Control of Dietary Supplements - Chromatographic Approaches for CGMP Compliance |
The dietary supplement industry has grown to become a multibillion-dollar-a-year market. Concurrent with this growth, the FDA has implemented new current good manufacturing practices (cGMP) regulations (21 CFR part 111) that mandate appropriate quality control and process control testing for dietary supplements, from incoming materials to finished goods.

Listen to the Data
One of the most frequent times that we discover a problem with a liquid chromatography (LC) method is when we examine a data set following the analysis of a batch of samples. This installation of “LC Troubleshooting" looks at some data submitted by a reader who suspected that something wasn't right with the results. |
