Division 5.5 Evaluation of quantityF1

United Kingdom

Calculate the areas of the peaks of the internal standard and the aliphatic esters of C ₄₀ to C ₄₆ using the integrator.

Calculate the wax content of each of the esters in mg/kg fat using the formula:

$ester, mg ∕ kg = \frac{A_{x} \times m_{s} \times 1000}{A_{s} \times m}$

where:

A _x

area of each ester’s peak, in square millimetres;

A _s

area of the internal standard’s peak, in square millimetres;

m _s

mass of added internal standard, in milligrams;

mass of sample for analysis, in grams.
