Abstract
Increased precision for liquid absorption spectroscopy, especially for in vivo samples of human analytes, is obtained by varying the signal or signal and interference central wavelengths when the temperature of the sample site varies beyond a selected threshold used for determining standardized signal or signal and interference central wavelengths. The amount of variance for a central wavelength of the signal beam which includes 1,150 nm is approximately 2 nm or less.
