Charged Aerosol Detectors

Corona Veo and Corona Veo RS

Page 64 Operating Instructions

5.5 Performing Sample Analysis

This section provides information for performing sample analysis with the detector. Before

you perform an analysis, set the operating parameters from the detector display

(→ section 5.3, page 48).

5.5.1 Starting and Stopping Data Acquisition

Before you start data acquisition, make sure that you have set the required parameters, and

that the system and the detector have equilibrated. You can start and stop data acquisition

and watch the progress of data acquisition on the display.

To monitor data acquisition on the detector display, see page 53.

To start data acquisition from the detector display

1. In the Main Menu, select the Run Mode soft key.

2. Equilibrate the detector as described in section 5.4.3 (→ page 62).

3. To monitor the progress of data acquisition on the display, see the Current parameter

on the Run Mode Menu that displays the online data signal in real-time (→ page 50).

4. To stop data acquisition, press the Exit soft key in the Run Mode Menu and on the

next screen, select Continue to Exit.

5.5.2 Operating the Stream-Switching Valve (Corona Veo RS only)

The stream-switching valve can be used to direct flow to the nebulizer or divert to external

devices or waste. In addition, the stream-switching valve will divert liquid away from the

detector in the event of an alarm condition.

When the detector is controlled from chromatography software, such as Chromeleon, the

valve can be actuated as part of the chromatographic method. This way, it can be used to

divert flow away from the detector as a timed function to eliminate unwanted peaks from

detection, thus simplifying the chromatogram.

Tip: If you operate the detector with another detector from chromatography

software, the valve can divert the liquid flow to the other detector or liquid

handling and/or collector device.
