Hello .... My name is Hassan alshwi of Iraq from the South Oil Company Assistant Chief I chemist working on a DIONX DX-120 suffer from problems regarding the liquid out of the ASRS add bubbles out of the WAST ....
and no tempature appear in LCD CAN YOU HELP ME PLEASE
You are using ASRS suppressor in which mode are you using. whether recycle mode. external water mode and chemical mode.
if you use in chemical mode no air bubble will not come out of suppressor
If you using External water mode and recycle mode you will find some air bubble coming out of suppressor.
Thank you for your interest to answer and help .... The problem is in AutoSuppression Recycle Mode
It is not external water mode or chemical mode ... The problem is when it runs continuously bubbles appear in the tube out and the fall of drops of liquid from it, Is it possible to clarify the accountability please
The problem that I suffer is due to high pressure, which reaches up to 1600 psi .. and I have worked on switching your columns and filter cleaning and isolate ASRS from work and stayed the same problem is there a solution to this Responsible please
Thanks for your prompt reply. Actaullay From suppressor REG OUT we will get bubble. This is not a problem How is your background total conductivity Signal
Then second regarding pressure you can check part by part. First pass eluent up to injection valve check the pressure , then connect guard colunm and check the pressure , then connect analytical column and check .so that we can find that which is giving high pressure
Thanks for the answer .. Is the flow of fluid from the body of ASRS, due to high pressure or there is another possible reason avoided ...Is it possible to know what is the acceptable range of pressure for a IC DX-120 with a single column
For column pressure 1300 to 1400 psi for 1 ml/min
For suppressor its must be 40 psi . if not clean with ASRS300 clean with 200mM of H2so4 and 0.2M of oxyalic acid
For CSRS clean with 200mM of NaOH and 0.2 M of oxyalic acid followed by water
Thank you very much for a quick answer ... I'm new in the field of work on ion chromatography .. How do I know that ASRA in a DX-120 is of any kind
WATER MODE, CHEMICAL MODE, OR AUTO SEP. MODE
And if I am not possessed pack pressure coil Does this affects the increased pressure on ASRS ?
defintely pressure is very important for Suppressor. we are recommeded the external water mode only. but if you want to run in external water mode you have one pressure regulator, 4litrre bootle. pressure must be only 2 psi. if you put high pressure then you suppressor will get damanged. be careeful when you do this.
Thanks for the help and advice .... thers no high pressure now its between (1300-1400) ... but thers leak in ASRS where the flow of the liquid FROM BUDY.
How could address this problem of science that I can not replace it with another
