It is neither necessary nor recommended to include all of the peaks
for a particular gas component. Users should employ the minimum
possible number of peaks within the gas database that results in the
best conditioning of the sensitivity matrix discussed in the software
manual.
Examples of application specific calibration gas mixtures and a
recommended cracking pattern matrix are normally provided with
quotation.
