Biofuel Analysis by GC, LC-MS, and HPLC

Article

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.
