For analysing biotin and folic acid in drinks, RSSL has developed and validated a liquid chromatography mass spectrometry (UPLC-MS) method that is faster and more sensitive than those used previously.
The new technique's speed and sensitivity gives clients greater confidence in claims substantiation.
Having invested in a top-of-the-range LC-MS instrument, RSSL is rapidly developing UPLC-MS methods for other vitamins and functional ingredients.
According to RSSL, UPLC-MS is a big step forward for analysis of vitamins and other functional ingredients.
The company also has a separate UPLC-MS set up that is devoted to investigative work, such as identifying contaminants and unknown compounds.
