LC-MS/MS Emerges As New Method of Analysis for Vitamin B Testing

BVitaminsAnalytical test methods for vitamin testing in foods have been in existence for decades, including microbiological and high performance liquid chromatography (HPLC) methods. While these methods are still considered the “gold standards” for vitamin testing, a new method, liquid chromatography tandem mass spectrometry (LC-MS/MS), is emerging. LC-MS/MS can offer several advantages over the older methods, including greater sensitivity, precision, simplified sample prep, quantitative dynamic range, and most importantly multiplexing.

This new method is an important solution for our food manufacturer sponsors, as it provides you with faster and more reliable data, as well as potential cost savings if you need a full B-vitamin profile. Continue reading
