What could cause the BSM pump to overpressure during a gradient? - WKB87594
Article number: 87594
ENVIRONMENT
ACQUITY UPLC BSM
ANSWER
- If a gradient table contains a rapid change from 100%A to 100%B (or vice versa), the Mixer can clog, especially if it is older and already has blockages forming.
- Pressure issues occur gradually but eventually manifest themselves in a full overpressure.
- Pressure traces show jagged tops, demonstrating the resistance to smooth fluidics.
