Pesticides in hempseed oil

P2625-RT covers the most relevant pesticides, which are used during cultivation of hemp. A selection of 8 to 15 pesticides are spiked.

The spiked pesticides include

• pesticides, covered by common pesticide multi-residue methods (LC and GC), and
• acidic herbicides (analysed without hydrolysis).

The aim of the ring test is

• the correct identification of the spiked pesticides,
• the correct quantification with respect to the
  comparability criterion (|z-score| ≤ 2),
• the correct quantification with respect to the
  trueness criterion (70-120 % recovery of the spiked level, as far as applicable).
