Dionex ASE 200

I have been working with Dionex ICS2000. Never had experience with this particular intrument. You best choice would be calling Dionex (actually it is Thermo Scientific now if I remember correctly) directly, they purchased it last year October). The company is pretty good with customer service. Thanks to J. Duan for providing this response to LabWrench.

you could check if your gas supply for the system is OK and if the overall system pressure is set to 50 psi, opening the front door of the instrument you may see it showing at a regulator. Also it can be something related with internal solenoid valves or any kind of blockage at the arm movement. Could you perform a rinse? If you need any more assistant you could call Dionex Support Center. Thanks to M. Chalom for providing this response.

I used to work for Dionex and if you call the Salt Lake number below they can offer support on the ASE 200, 1182 W. 2400 S, Suite 8A Salt Lake City, UT 84119 United States Phone: +1 801 972 9292 Fax: +1 801 972 9291 Thanks to A. Bellinger for providing this response.

you need almost 100 PSI of gas supply for the needle to work. does it actually try to move or just set still? I have to agree with Ann as will Salt lake people know the best about these instrument, we actually have ASE300, that experienced similar problem, and it was the gas supply pressure.

I too use to work for Dionex. I agree check the gas pressure, should be set between 50-60 psi as I recall. Other than that the folks at Dionex SLTC should be able to help. Best of luck. Thanks to D. Jarzinski for providing this response.
