λ/ Absorbance formula:

1.Press Absorbance Formula.

2.The formula selected in the top key determines the number of wavelength and coefficent keys that will appear below. To change the absorbance formula, press the top key, select a formula from the displayed list and press OK. When a new formula is selected, the number of variables below changes to match.

The following formulas are available:

K1 A 1 + K 2 A 2

K 1 A 1 + K 2 A 2 + K 3 A 3

K1 A 1 + K 2 A 2 + K 3 A 3 + K 4 A 4 K 1 A 1 / K 2 A 2

(K 1 A 1 + K 2 A 2 ) / K 3 A 3

(K 1 A 1 + K 2 A 2 ) / (K 3 A 3 + K 4 A 4 )

A 1 refers to the absorbance at wavelength 1

A2 refers to the absorbance at wavelength 2, etc. K 1 refers to the coefficient at wavelength 1

K 2 refers to the coefficient at wavelength 2, etc.

Coefficients can be set negative where subtraction is required.
