Taking a representative sample:
The analytical result is only as good as the sample submitted for analysis. Collecting a representative sample is the first step of the analytical procedure.
Grains & Mixed Feeds: Bulk loads: Randomly collect around 10 samples as the grain is discharged and combine in a clean plastic bucket. Submit at least 500 g for analysis. Bags: collect grab samples from as many different areas of the bag(s) as possible, mixing if possible to ensure a good representative sample is taken. Submit at least 100g for analysis
