Highlights from the 2016 Archives
Selected highlights from The Columns 2016 archives.
1. Split Injection GC: Inlet Liner Choice for Shoot and Dilute GC
Jack Cochran’s “Practical GC” provided readers with practical advice and new experimental evidence for how to get the best results from their gas chromatography (GC) systems. This instalment looked at GC inlet liner choice for “shoot and dilute” GC.
2. Onshoring Your Insourced Solutions?
Incognito debated the pros and cons of onshore support.
Raquel Garcia and Maria João Cabrita revealed the theory and practical applications of molecularly imprinted polymers (MIPs).
4. Detecting Carcinogens in Water
Koji Kosaka of the National Institute of Public Health, Japan, spoke with The Column about his use of high performance liquid chromatography (HPLC) to uncover the source of contamination in the Yodo River Basin in Japan, with the precursors of the carcinogen N-Nitrosodimethylamine (NDMA).
Protein biopharmaceuticals have seen an enormous growth in the last decade, and as a result, separation scientists are giving increased attention to methods for characterizing biopharmaceuticals. One powerful technique for analyzing proteins is two-dimensional liquid chromatography (2D LC). Gerd Vanhoenacker of the Research Institute for Chromatography (RIC) in Kortrijk, Belgium, spoke to The Column about his research into peptide mapping of therapeutic monoclonal antibodies (mAbs) using 2D LC.
Jean-Luc Veuthey and Alexandre GrandâGuillaume-Perrenoud revealed the latest developments in supercritical fluid chromatography (SFC) that are bringing the technique back to the limelight.
7. FPLC versus Analytical HPLC: Two Methods, One Origin, Many Differences
This article discussed the differences between the two techniques with particular emphasis on the requirements of their respective analytes.
8. Contemporary Trends in Ion Chromatography
Ion chromatography coupled to mass spectrometry (IC-MS) does not follow the same rules as coupling other modes of liquid chromatography to mass spectrometry (LC–MS). Leon Barron from the Analytical & Environmental Science Division, at King’s College London, UK, revealed some of the misconceptions surrounding IC and discussed contemporary trends and novel applications for this inventive technique.
9. The Value of Chemometrics and Experimental Design to Analytical Chemists
Kevin A. Schug considered what the study of chemometrics and experimental design statistics can add to an analytical chemist’s work.
10. System and Column Volumes in HPLC: We Still Haven’t Gotten the Message
What is required to produce a highly efficient modern high performance liquid chromatography (HPLC) system/column combination? This instalment of the LCGC Blog explained more.

Inside the Laboratory: The Richardson Group at the University of South Carolina
November 20th 2024In this edition of “Inside the Laboratory,” Susan Richardson of the University of South Carolina discusses her laboratory’s work with using electron ionization and chemical ionization with gas chromatography–mass spectrometry (GC–MS) to detect DBPs in complex environmental matrices, and how her work advances environmental analysis.
AI and GenAI Applications to Help Optimize Purification and Yield of Antibodies From Plasma
October 31st 2024Deriving antibodies from plasma products involves several steps, typically starting from the collection of plasma and ending with the purification of the desired antibodies. These are: plasma collection; plasma pooling; fractionation; antibody purification; concentration and formulation; quality control; and packaging and storage. This process results in a purified antibody product that can be used for therapeutic purposes, diagnostic tests, or research. Each step is critical to ensure the safety, efficacy, and quality of the final product. Applications of AI/GenAI in many of these steps can significantly help in the optimization of purification and yield of the desired antibodies. Some specific use-cases are: selecting and optimizing plasma units for optimized plasma pooling; GenAI solution for enterprise search on internal knowledge portal; analysing and optimizing production batch profitability, inventory, yields; monitoring production batch key performance indicators for outlier identification; monitoring production equipment to predict maintenance events; and reducing quality control laboratory testing turnaround time.
