ABSTRACT:
A method identifies components in a sample by spectrally analyzing the sample in a spectrophotometer. The sample data points output from the spectrophotometer are detected in a detector before being stored in an array in a data station. A preselected smoothing bandwidth is entered into the data station from a keyboard. The bandwidth is converted to a strength parameter; and thereafter each of the smoothed data points is stored before being output as an array of smoothed data points to form a modified spectral display, which identifies the components in the sample.
