| Remarks | Two Samples with parameters in a Food Matrix are provided for qualitative (Lactose) and quantitative (Lactose + Fructose) determination. One of these samples and the "Spiking Level Sample" were prepared adding the Lactose and Fructose. The "Spiking Level Sample" contains the parameters in a simple matrix in similar amounts. The Lactose amounts are approx. 70 - 250 mg/100g. The evaluation of results will be qualitative (Lactose) and quantitative. For information DLA calculates a recovery rate of Lactose for the "positive"-sample and the "Spiking Level Sample". Any suitable method can be applied for analysis. | |||||||||
