ACQUITY UPLC FLR Detector leaking flow cell on BioAccord System - WKB194991
Article number: 194991
SYMPTOMS
- Leak observed from ACQUITY UPLC FLR Detector flow cell
ENVIRONMENT
- ACQUITY UPLC I-Class
- ACQUITY UPLC FLR Detector
- BioAccord System
CAUSE
High backpressure on the cell caused cell failure. Fittings checked and a kink observed in the capillary from the divert valve to source enclosure
FIX or WORKAROUND
1. Replace RDa capillary, part number: 700011871
ADDITIONAL INFORMATION
Flow applied to system at method flow rate of 0.4ml/min. Switching flow on divert valve between waste and MS showed a 1000psi increase in backpressure when flowing to the MS. FLR flow cell has a backpressure limit of 500psi
