You can edit detector parameters when the system is idle by clicking the underlined value. You
cannot edit these values while the system is running samples.
Figure 3–9: TUV detector control panel
The following table describes the items in the TUV’s control panel:
Lamp LED
– Mirrors the lamp status LED on the front panel of the detector, unless
communications with the detector are interrupted.
Lamp ignition
– When clicked, ignites or extinguishes the lamp. If the icon is green, the
lamp is ignited. If the icon is gray, the lamp is off. If the icon is red, the lamp is in an error
state.
Value of wavelength A
– Displays the value of wavelength A, in nm. If the detector is in
dual wavelength mode, the value of wavelength B also appears.
AU
– Displays the absorbance units of wavelength A. If the detector is in dual wavelength
mode, the absorbance units of wavelength B also appears.
Status
– Displays the status of the current operation.
You can access these additional functions by right-clicking anywhere in the detector control
panel.

3.6.10 ACQUITY QDa
The ACQUITY QDa mass detector characterizes LC-separated analytes, determining their mass
by means of a photomultiplier detection system and chromatography data software. The
instrument acquires data in one of these operating modes:
