Solution preventing decomposition of samples
WebSamples for analysis were taken from infusates and each bag during simulated infusion. Degradation of vitamins A and E was determined by stability-indicating HPLC analysis. Results: Results indicated that vitamin A loss proceeded rapidly during infusion, resulting in up to 80% loss in 6 hours, even with light protection of the bag. WebSediment trap samples need to be preserved in situ to prevent degradation during …
