Acetamiprid [649]

 

Content Handbook L

 

Outline of method

Acetamiprid is determined by high performance liquid chromatography on a column (C18) using acetonitrile + water + 10% phosphoric acid solution as mobile phase, UV detection at 246 nm and coumarin as internal standard.

*Acetamiprid is determined by high performance liquid chromatography on a CN column using n-heptane + ethanol as mobile phase, UV detection at 254 nm and p-nitroaniline as internal standard.

 

 

Scope

The objective is to accelerate the ageing of a product by heating. No evidence is available to indicate that a product which has failed this test has a satisfactory shelf life (of at least 2 years) either in the tropics or in temperate zones.
The method is usable for TC, SP, SG SL and *EC-formulations.
