Detection system
The long path length and small volume of the flow cell ensure very high sensitivities and
high signal-to-noise ratios. The detection system is also very stable and because the
optical unit is located away from the lamp and electronics, noise and drift caused by
temperature variations is avoided.
Calibration
At calibration the instrument automatically finds two persistent lines in the spectrum of
Xenon. The wavelengths of these known lines are used to calibrate the stepper motor
that turns the grating.
