- Set temperature is 4 °C
- Console reads 6.6 °C
- Sample manager was defrosted
- ACQUITY UPLC Sample Manager
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
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.
