Notes to the performance criteria:
The Horwitz equation(1) (for concentrations 1,2 x 10-7 ≤ C ≤ 0,138) and the modified Horwitz equation(2) (for concentrations C < 1,2 × 10-7) are generalised precision equations which are independent of analyte and matrix but solely dependent on concentration for most routine methods of analysis.
Modified Horwitz equation for concentrations C < 1,2 × 10-7:
RSDR = 22 %
where:
RSDR is the relative standard deviation calculated from results generated under reproducibility conditions
C is the concentration ratio (i.e. 1 = 100g/100g, 0,001 = 1 000 mg/kg). The modified Horwitz equation applies to concentrations C < 1,2 × 10-7.
Horwitz equation for concentrations 1,2 x 10-7 ≤ C ≤ 0,138:
RSDR = 2C(-0,15)
where:
in point C.3.3.2., ‘Fitness-for-purpose’ approach, the words ‘Table 8’ are replaced by the words ‘Table 10’.
