Performance criteria of the instrumental method of analysis

(a)

The detection limit for lead and cadmium must be equal to or lower than— 0,1 mg/litre for lead; 0,01 mg/litre for cadmium.

The detection limit is defined as the concentration of the element in the 4 % acetic acid solution, as referred to in paragraph 3(a) which gives a signal equal to twice the background noise of the instrument.

(b)

The limit of quantification for lead and cadmium must be equal to or lower than— 0,2 mg/litre for lead; 0,02 mg/litre for cadmium.

(c)

Recovery. The recovery of lead and cadmium added to the 4 % acetic acid solution, as referred to in point 3(a), must lie within 80-120 % of the added amount.

(d)

Specificity. The instrumental method of analysis used must be free from matrix and spectral interferences.
