Abstract
The present invention relates generally to a slope spectroscopy standards and methods of making slope spectroscopy standards, specifically standards and methods of developing standards specifically for variable pathlength (slope) measurements.
Claims7
A method of making a slope spectroscopy standard for a compound comprising:
- selecting a compound;
- determining the slope at a predetermined concentration of the compound;
- determining a concentration of a methylxanthine standard which corresponds to the compound slope by using variable path length spectroscopy wherein the compound and the standard are different compounds and wherein the compound and the standard have absorbance spectra that share a common absorbance wavelength;
- and
- making a standard of an appropriate concentration which provides a slope measurement that corresponds to that of the compound wherein the standard has a slope measurement of from about 0.01 to 500.
