Sudan Colour Analysis at Eclipse

Tuesday 30 November 1999

In our current method, samples are extracted by a technique equivalent to that used in Food Standards Agency surveys; extracts are then examined using HPLC with diode array detection. Spiked recovery samples are included with every batch, as a method quality control measure.

The reporting limit is 1 mg/kg (ppm) and, in a recent FAPAS ring trial, we obtained an excellent z score – giving us independent assurance of the reliability of our method.

Development of a method giving significantly lower limits of detection is almost complete: these limits are matrix dependent and we can provide further details on request.

In conjunction with our R & D Team, we are also working on an LC-MS method, with lower detection limits and immediate confirmation of any positive results.
