5.2.2 Calibration Matrix Page
The Calibration Matrix page (Figure 5-5) allows for viewing of the calibration matrix used by
the spectrometer for the analysis of the gas.
Click on the page to present the calibration matrix used by the spectrometer (Figure 5-3 in
the determination of the H
2
S concentrations. The calibration matrix is uniquely determined for
a particular spectrometer.
Figure 5-5: Calibration Matrix
If a spectrometer is replaced, a new calibration matrix must be loaded onto
the system computer. Consult Galvanic Applied Sciences for the
procedure.
The calibration matrix is a 9 x 530 element array used in conjunction with the computed
absorbance vector to determine the concentration of the H2S present in the measurement
cell. Galvanic Applied Sciences, Inc. determines the calibration matrix by incorporating H2S
molar absorptivity data with the specific spectral resolution and sensitivity characteristics of a
particular spectrometer. The purpose of displaying the contents of the calibration matrix is to
provide a means of matrix identification, should the need arise.
