Challenges in Obtaining Relevant Information from One- and Two-Dimensional LC Experiments
June 2nd 2020To address the quest for greater separation power, the chromatographic community developed comprehensive two-dimensional liquid chromatography (LCxLC). But even with LCxLC, it can still be challenging to analyze highly complex samples and obtain accurate and correct information. In this article, opportunities for optimizing methods for extracting maximum information from one-dimensional (1D)-LC and two-dimensional (2D)-LC chromatographic data are explained.
Stability Studies and Testing of Pharmaceuticals - An Overview
June 1st 2020Determining product shelf life is a regulatory requirement for pharmaceuticals and many other regulated consumer products. In this comprehensive overview of stability studies and testing, we summarize current regulatory requirements, share industry practices for forced degradation, and explain approaches for reduced testing and data evaluation to expedite stability study timelines.
Multidimensional Separation Techniques for Characterization of Biotherapeutics
June 1st 2020Multidimensional separations, in which two or more separation methods are coupled, are a valuable analytical tool for higher peak capacity and improved selectivity for the analysis of complex samples like biotherapeutics.
Are You Controlling Peak Integration to Ensure Data Integrity?
June 1st 2020Chromatography data systems (CDS) have been at the center of multiple FDA 483 citations and warning letters, with an emphasis on peak integration and interpretation of chromatograms. Here, we review the issues associated with ensuring compliance when performing peak integration.
Recovering from a COVID-19 Shutdown: Tips and Tricks for Starting Up, Part 1
June 1st 2020COVID-19-related laboratory shutdowns are sure to cause a myriad of problems with liquid chromatography (LC) instrumentation across the globe. Taking a systematic approach to restarting these systems will save time and money in the long run, by preventing problems that may otherwise appear in days or weeks following startup.
Stability Studies and Testing of Pharmaceuticals: An Overview
June 1st 2020This instalment is the first in a series of three white papers on stability studies and testing of pharmaceuticals, as well as the development and validation of stability-indicating high performance liquid chromatography (HPLC) methods. The series is co-authored by Kim Huynh-Ba, a subject-matter expert on stability testing and regulatory compliance, and Michael Dong, the columnist on “Perspectives in Modern HPLC”. This first instalment provides a comprehensive and updated overview of stability studies and testing of small molecule drugs, current regulatory requirements, and industry practices for forced degradation, as well as possible approaches for reduced testing and data evaluation to expedite stability study timelines.
Investigating Contamination in Biocompatible LC Systems
May 6th 2020Biocompatible LC systems are generally regarded to be chemically more inert than conventional HPLC systems. However, a study into the chromatographic behaviour of some classes of compounds analysed on these iron-free HPLC systems revealed issues typically associated with metal contamination.

The LCGC Blog: The Last Dance, for a While—Time to Share the Wealth
May 4th 2020My initial inclination was to write about something other than the current status of life, given the threats of coronavirus. However, after a month extension to the shelter-in-place was ordered by the U.S. government this past weekend, and after various e-discussions with friends and colleagues throughout the world who are experiencing similar challenges, I felt I might have something to offer to make life easier.
How Do You Write User Requirements for Chromatographs and Chromatography Data Systems?
May 1st 2020One of the biggest failures with purchasing chromatograph systems and chromatography data system (CDS) software is either the total lack of or poorly written user requirements. So, how can you write acceptable requirements? Is specifying a chromatograph the same as software?
