Entering the AS/AS50 Inject Port Volume

The inject port volume is the volume of tubing between the AS or AS50 inject port and the injection valve. The autosampler uses this information to determine how much fluid to push through the line in order to position the sample correctly in the loop for precision injections.

 

When to enter a new inject port volume:

After manually calibrating the inject port volume on a new or existing needle seal assembly. 

 

For detailed instructions on replacing a needle seal assembly or calibrating the inject port, refer to the AS or AS50 operator's manual.

  1. Open the System Wellness Control Panel for the autosampler (see  Opening a Wellness Control Panel).

  2. In the Inject Port Volume field, enter the volume determined during calibration of the inject port volume on a new or existing needle seal assembly.

  3. Press <Enter>. Chromeleon downloads the value to the autosampler and stores this calibration value as the current value.
