TEST PROCEDURE
- Grind a representative sample. Weigh out a 2.0 g sample into the centrifugal tube.
- Add 2 mL of Diluent A and 8 mL of ethyl acetate.
- Shake for 5 min.
- Collect 2 mL of supernatant into a small container.
- Dry the liquid by blowing wind.
- Redissolve the residues with an amount of Diluent B. (REF: Table)
Cut-off (ppb) | 100 | 200 | 500 |
Diluent B (mL) | 0.4 | 0.8 | 2.0 |
- Place a cassette horizontally.
- Drop 3 drops into the assay sample hole.
- Interpret the result visually in 5-10 minutes.
