Example: Waters Alliance 2695 Inline Degasser ERRORS and Troubleshooting Tips (Acquity tips are similar):
Degasser hardware fault OR vacuum h/w fault error on your Waters brand HPLC system? High RPM warning or vacuum pressure over 0.9 psi? Do you hear a loud knocking sound or whine coming from the degasser pump? These errors often indicate that your degasser vacuum pump is worn out ,you have vacuum leaks in the tubing and/or damaged degassing chambers. However, before you send in your degasser module to us for diagnostic testing or service, please be sure you review and address the following possible causes of errors. BEFORE REPLACING PARTS OR SENDING THE DEGASSER OUT FOR PROFESSIONAL SERVICE, PLEASE CHECK THESE BASIC THINGS FIRST.
- Have you properly purged the system? Make sure that ALL CHANNELS have fresh fluid inside them. The degassing system is NOT designed to be operated with air inside any of the vacuum channels. PURGE each of the channels, one-at-a-time, with mobile phase. NEVER plug a chamber because you are not using it (the liquid inside a plugged channel will quickly evaporate leaving air inside). If you have one or more degasser channels that are not being used, please connect the unused channel in-line to a channel that is being used to keep it filled with fluid at all time. Use a low pressure connection line to connect it in-series (we often call these lines 'C' tubes because they loop back like the letter c).
Loud noise coming from the vacuum degasser of a 2695 or other system ? If so, the pump has been broken for a very long time and the system should be shut down until it can be serviced. The damaged vacuum pump has probably contaminated the vacuum flow path and will need to be cleaned.
- Do you hear a loud whining noise from the degasser vacuum pump? If so, the pump is damaged and the system should be shut down until it can be serviced.
OTHER THINGS TO THINK ABOUT OR DO:
- Have you observed ANY liquid in the vacuum pump exhaust line? If so, the system has internal damage and requires professional testing to find out which part or parts require replacement or repair. The vacuum system should be dry at all times.
- Perform the Inline Degasser Test using the Waters Service Menu. The test takes ~ 15 minutes to run and is accessible under the instrument Service window. To run the "Inline Degasser Ramp and Decay Test" (or other degasser tests), select "Degasser" from the 'Other Diagnostics' screen, then press OK. The Degasser Test screen will appear. Follow the on screen instructions. This is a Pass/Fail test.
- When was the last time your HPLC degasser was professionally serviced and refurbished? If it has been more than five (5) years, then it is due for diagnostic testing and service. Some of the parts used in the degasser have a mean lifetime of only 5 years (under ideal conditions) and as the parts wear, they may introduce degradation products from the internal wear directly back into your mobile phase resulting in ghost peaks, poor HPLC performance and other issues. In-House Professional Diagnostic testing of your HPLC degasser is very inexpensive and allows Chiralizer Services to quickly identify which parts require cleaning, service or replacement so you only pay for what needs to be fixed (other vendors charge you to replace the entire module!).

Testing and Repair Takes just 2 Business Days ! Super Fast Turnaround times.
These modules most commonly fail after five years of service. Replacement of the most common broken degassing module parts with new, refurbished or higher quality after market parts to meet most budgets are offered. We can also customize and improve the degassing module's performance with smaller volume vacuum chambers to reduce delay volume, flushing and solvent change-over times without decreasing vacuum degassing capacity. The diagnosis, repair and testing are all done in our shop by experienced professionals.
We provide professional diagnostic and repair services for Waters, Shimadzu, HP, Agilent, Thermo, Dionex and many other brands of HPLC DEGASSER modules. Please contact us with your detailed contact information and the degasser model AND serial number for more information. Chiralizer™ Services, LLC, USA
