Reading Scientific Services (RSSL) has developed and validated liquid chromatography - mass spectrometry (UPLC-MS) methods for analysing biotin and folic acid in drinks.
The UPLC-MS technique is said to be quicker and more sensitive than previously used methods.
The company is also developing UPLC-MS methods for other vitamins and functional ingredients.
According to Marta Ahijado Fernandez, laboratory manager for RSSL's Functional Ingredients laboratory, UPLC-MS equipment is suitable for the routine analysis of known compounds.
'We also have a separate UPLC-MS set up, which is devoted to investigative work, such as identifying contaminants and unknown compounds,' said Fernandez.
