Lamp Intensity Test

The intensity test scans an intensity spectrum via the reference diode (200 – 1200 nm in 1 nm steps) and stores it in a diagnosis buffer. The scan is displayed in a graphic window. There is no further evaluation of the test.

Results of this test are stored as lamp history (date code, intensity).

NOTE

The profile can vary from instrument to instrument. It is dependig on the age of the lamp and the content of the flow cell (use fresh water).

UV degradation, especially below 250 nm is significantly higher compared to visible wavelength range. Generally the "LAMP ON during run" setting or using "economy mode" will increase lamp life by a magnitude.
