US Patent 4510072: Composition having neutralized differential…
US 4510072 · granted 1985-04-09
Abstract
A composition which is added to liquid samples undergoing double wavelength infrared analysis exhibits no net differential effect on the double wavelength channels. The composition is formulated by selecting one compensating component for each double wavelength channel, wherein said compensating component offsets the net differential effect exerted by the remainder of the composition.

The composition is formulated by selecting one compensating component for each double wavelength channel, wherein said compensating component offsets the net differential effect exerted by the remainder of the composition.
Claim 1
A composition which, when added to a liquid sample, will exhibit an equivalent increase in infrared absorbence at preselected first and second wavelengths, said compositioncomprising: one or more primary components which together exhibit a first absorbency at said first wavelength and a second absorbency at said second wavlength; and a compensating component which exhibits a first absorbency at said first wavelength and a second absorbency at said second wavelength, said compensating component being present in a predetermined amount so that the sum of the first absorbenciesof both the primary and compensating components will substantially equal the sum of the second absorbencies of both the primary and compensating components.
