Abstract
A method and apparatus of determining peak positions in a spectrum of data includes providing a spectrum of energy to a sample and measuring the spectrum of energy after contact with the sample to provide a range of spectrum data representative of the sample. The spectrum data is then subjected to a differential calculus operation of an even number to provide a differential spectrum data. The spectrum data and differential spectrum data are combined whereby the characteristics of the components in the sample are enhanced. The combined data is then analyzed so that the components in the sample can be identified.
