How do I set reverse polarity for an inject event with a Beckman CE under Empower control? - WKB46506

OBJECTIVE or GOAL

Create a reverse-polarity inject event in an instrument method for a Beckman CE under Empower using the Beckman CE driver v1.2.1.

ENVIRONMENT

• Empower
• Beckman CE v1.2.1

PROCEDURE

Enter a negative value for the voltage.

ADDITIONAL INFORMATION

The following information appears in the Beckman CE v1.2.1 Driver User Manual:

Voltage
This text box allows you to specify the voltage to be applied during the Inject Event. The valid range is – 10.0 to 10.0 kilovolts (kV). The default voltage is 1.0 kV. The values between -10.0 and - 0.1 kV indicates the Reverse polarity and values from 0.1 to 10.0 kV the Normal polarity, with Normal being the default. Normal is + at the inlet (left) and – at the outlet (right). Reverse is – at the inlet (left) and + at the outlet (right).
