Division 6.2 Variation of the specific extinction (ΔΚ)F1

United Kingdom

The variation of the absolute value of the extinction (ΔΚ) is given by:

$Δ K = |K m - (\frac{Kλ m - 4 + Kλ m + 4}{2})|$

where Km is the specific extinction at the wavelength for maximum absorption at 270 nm and 268 nm depending on the solvent used.

The results should be expressed to two decimal places.
