Issue

Condensation inside of AS-AP autosampler

Environment

AS-AP autosampler carousel 

Resolution

  1. Use paper towels to soak up as much liquid as possible on the trays, well plates, and bottom of the carousel.
  2. Verify the condensation fan is ON and set to MAX per the Operator's Manual.  Reference "Condensation on Vial Tops and Well Plate Covers".  065361 - Rev 07 - AS-AP Operator Manual.pdf

Turn on the condensation fan. The fan blows air recycled from the carousel area onto the top of the vials or well plates and prevents condensation from forming. To turn on the condensation fan, open the autosampler ePanel (in Chromeleon 7) or Control panel (in Chromeleon 6.8) and press F8. Under Sampler, set the CondensationFan property to Normal or Max.

  1. Verify the peristaltic pump tubing connections are properly connected (flashlight and mirror will help).  Reference p. 167 of the Service Manual.  065437 - Rev 01 - ICS Series AS-AP Autosampler Service Manual
  2. Verify the peristaltic pump is running for one minute every 10 minutes during operation.  Reference Release Notes for Firmware version 1.3.0.  AS-AP Firmware v 1.3.0 Release Notes
  3. Verify proper drainage tubing flow if possible, modify/vent as shown below.
