2015/3/25 · We use both acidic and basic buffers. If you have the seal wash options, you should make use of them to flush away the tiny amount of buffers that normally seep past the piston seals. Using the wash would prevent the buildup of buffer salts that wear out the piston seals. Re: Aijiren Pump leaks. kubowicz.tomasz.

Issue: Stuck or obstructed check valves (Active Inlet Valve (AIV), Passive Inlet Valve (PIV), Outlet Ball Valve (OBV)) can cause issues such as no-flow or no-pressure, moderate to strong drops in pressure or retention time shifts. You can see the article How to Troubleshoot no flow or no pressure issues: Binary/Quaternary/Isocratic Pumps - G131XX, and G711XX to troubleshoot
2018/12/20 · Aijiren Pump Leak Rate Test failure: I have an Aijiren Binary Pump that consistently fails the Pump Leak Rate Test. Testing @ bar with 100% IPA. "A" side is fine. "B" secondary passes, and primary starts out OK, but after a few seconds, the pressure drops ~300bar, then goes back up to , leaving a v-shaped notch in the top of

2009/3/10 · Yesterday I equilibrated the system with 70:30 MeOH:H2O and noticed that pressure ripple from 1 to 10 bar. Baseline looked like a constant wave form. The first step I did is to release the purge value, purge all channels. Hence I find that there is a stable pressure/baseline for Channel B/C/D. Still have ripples in A (H2O).

II High Speed Pump User Manual 109 Maintenance 7 Cleaning the Module Cleaning the Module To keep the module case clean, use a soft cloth slightly dampened with water, or a solution of water and mild detergent. WARNING Liquid dripping into the electronic compartment of your module can cause shock
Between plus and minus 1, the tuning indicates that the pump is performing up to its specifications. For values (-1)-(-2), this could indicate air in the pump or wrong compressibility settings. Best here to use the "conditioning" function in the prepare pump context menu when you right click on the pump driver.
I have pressure problems in a Binary Pump ( ) because in most of the manteinances and repairs it had in the past the pump head assembling process was performed without the service kit. In this moment the pump cannot work with pressures above 600 bar.
2009/7/22 · I then switched back to 100% water on channel A and 100% Methanol on channel B, and used the binary pump to mix 50:50. Baseline is noisy again. So, I suspect the mixing system in the pump is not performing adequately. However, the pump diagnostics do not indicate any part of the pump as malfunctioning (leak test passed fine, no problems).
