| Abstract: | The functional instability of infrared spectrometers can result in serious errors of analysis. This work shows that the stability can be tested by means of the serial correlation method, and the various causes of unstable conditions and equipment faults identified. Drift and large oscillations present separately or together can be detected by new statistics developed from the serial correlation method. |
