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 one or more damaged degassing vacuum 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 PERFORM THESE BASIC CHECKS FIRST.

Have you properly purged the system? Make sure that ALL VACUUM CHAMBERS / CHANNELS have fresh mobile phase 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 fresh mobile phase (100% 'A', 100% 'B' etc, not 25%/25%...). NEVER plug a chamber because you are not using it (the liquid inside a plugged channel will quickly evaporate leaving air inside. Never operate with air in any channel). If you have one or more degasser channels that are not being used, then connect the unused channel(s) in-line to another 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 short lines 'C' tubes because they loop back like the letter 'c').

Loud knocking or "whine" noise coming from the vacuum degasser of a 2690, 2695, 2790, 2795, Alliance or Acquity system ? If so, the vacuum pump has been broken for a very long time, the system is contaminated and the system should be shut down until it can be professionally serviced. The damaged vacuum pump has probably contaminated the vacuum flow path and will need to be cleaned. The vacuum sensor and all vacuum chambers will need to be cleaned and checked too.

Have you observed ANY liquid in the vacuum pump's exhaust line? If so, the system has internal damage, contamination and requires professional testing to find out which part or parts require replacement or repair. The vacuum system should be dry at all times. The exhaust line should be unobstructed (no kinks) and open to the atmosphere.

OTHER THINGS TO THINK ABOUT OR DO:

If available, perform the Inline Degasser Test using the Waters Service Menu (*fully prime the system BEFORE starting the test). 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 (This test does not evaluate for contamination).

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 overdue for diagnostic testing and service. Some of the parts used in the degasser have a mean lifetime of only 4 or 5 years (maximum, 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!).

Never skip diagnostic testing and just replace the vacuum pump. Doing so will almost certainly result in internal contamination or damage to the new pump. Have the cause of the failure professionally diagnosed first, then have the degasser module professionally serviced. This is the scientifically correct way to solve the problem and maintain instrument compliance. Professional testing will save you money and time.

Chiralizer Services provides professional repair services for many of the Waters brand HPLC degasser modules including the Waters Inline Degasser-AF and the integrated degassers found in the Waters Alliance 2690, 2695, 2790, 2795, 1525, Acquity BSM and Acquity QSM, UPLC and nano Acquity. Replacement Waters P/N 700001352 vacuum pumps and vacuum chambers are also available at greatly reduced prices over Waters retail prices.

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.

When you send your Waters brand degassing module to Chiralizer Services, we will correctly determine which parts of your degasser are defective and send you a formal quotation to replace them and test the system. We do charge a nominal diagnostic fee to evaluate and test your degasser, but you retain control over the decision to have it repaired or not. To arrange to have Chiralizer Services in the USA professionally test your Waters Alliance or Acquity (or any other brand/model) HPLC degasser, please give us a call or send us an email to discuss your needs and we can forward you shipping return instructions. For the fastest response, please include your complete contact information (company name, street address, phone etc), the make, model and SERIAL NUMBER of the degasser (or the S/N of the HPLC system it came out of) so we can send you a Diagnostic Testing Quote.

We provide professional diagnostic testing and repair services for Waters, Shimadzu, HP, Agilent, Thermo, Dionex and many other brands of HPLC DEGASSER modules in the USA. Please contact us with your detailed contact information and the degasser model AND serial number for more information. Chiralizer™ Services, LLC, USA
