Biofuel Analysis by GC, LC-MS, and HPLC
Biodiesel Magazine has recently posted an article that gives an overview of biodiesel test methods, which includes gas chromatography (GC), infrared spectrometry (IR), and inductively coupled plasma (ICP).
Biodiesel Magazine has recently posted an article that gives an overview of biodiesel test methods, which includes gas chromatography (GC), infrared spectrometry (IR), and inductively coupled plasma (ICP).
While IR and ICP have more to do with our sister publication Spectroscopy, Chromatography Online has several articles regarding the quality control and identification of blend levels by GC. We have published several application notes regarding the analysis of free and total glycerines in biodiesel, which can be found here and here.
We have also published an application notes on the liquid chromatography-mass spectrometry (LC-MS) analysis of biodiesel and the high performance liquid chromatography (HPLC) method that uses an evaporative light scattering detector as described in another note. These LC and HPLC are mentioned in the Biofuel Magazine's article which focuses on official EPA methods for the identification of biofuels.
LCGC’s Year in Review: Highlights in Liquid Chromatography
December 20th 2024This collection of technical articles, interviews, and news pieces delves into the latest innovations in LC methods, including advance in high performance liquid chromatography (HPLC), ultrahigh-pressure liquid chromatography (UHPLC), liquid chromatography–mass spectrometry (LC–MS), and multidimensional LC.
Next Generation Peak Fitting for Separations
December 11th 2024Separation scientists frequently encounter critical pairs that are difficult to separate in a complex mixture. To save time and expensive solvents, an effective alternative to conventional screening protocols or mathematical peak width reduction is called iterative curve fitting.
Mobile Phase Buffers in Liquid Chromatography: A Review of Essential Ideas
December 11th 2024In this installment of "LC Troubleshooting," Dwight Stoll discusses several essential principles related to when and why buffers are important, as well as practical factors, such as commonly used buffering agents, that are recommended for use with different types of detectors.
The Chromatographic Society 2025 Martin and Jubilee Award Winners
December 6th 2024The Chromatographic Society (ChromSoc) has announced the winners of the Martin Medal and the Silver Jubilee Medal for 2025. Professor Bogusław Buszewski of Nicolaus Copernicus University in Torun, Poland, has been awarded the prestigious Martin Medal, and the 2025 Silver Jubilee Medal has been awarded to Elia Psillakis of the Technical University of Crete in Greece.
