ACQUITY UPLC Sample Manager compartment is not cooling to set temperature of 4 °C - WKB2093

Article number: 2093

SYMPTOMS

  • Set temperature is 4 °C
  • Console reads 6.6 °C
  • Sample manager was defrosted

ENVIRONMENT

  • ACQUITY UPLC Sample Manager

CAUSE

The lab ambient temperature was 24.6 °C, above the specification for cooling to 4 °C.

FIX or WORKAROUND

At a reading of 6.6 °C, sample manager cooling is performing as expected, within specified tolerance for these ambient conditions.

  • For ambient temperatures above 21 °C , the sample manager cools to 17 °C below ambient temperature, with -2/+6  °C tolerance

ADDITIONAL INFORMATION

The Sample Manager specification listed in the ACQUITY UPLC System Operator's Guide states that at an ambient temperature of 21 °C (69.8 °F) or lower, the sample manager maintains the temperature of the sample compartment down to 4 °C (39.2  °F), with a tolerance of -2/+6 °C (-3.6/+10.8 °F), when configured with the maximum number of vials and/or plates.
