ALS Life Sciences as part of the ALS Food & Pharma Group has an established reputation as a leading provider of analytical testing services for vitamins and additives. Offering a comprehensive range of accredited tests, customers receive fast and accurate analysis of their samples through the use of HPLC, Biacore (SPR) technology and microbiological assay techniques with robotic diluters where appropriate.
