Help with a Chemstation A.06.03

[Synergy]

Hello,

I am using a HP5890 with a 7673 autosampler with Chemstation A.06.03.

Everything was working fine on the front injector, for months, and I installed a column on the rear. Everything worked fine on the rear, then I tried to go back to the front.

The auto sampler stopped working. If you started a method, the GC would just start without the auto sampler doing anything. I made sure the auto sampler was plugged into the right port. None of the methods I made for the front would work. The auto sampler would work fine on the rear.

I tried rebooting, I tried rebooting and load the default method, nothing would get the auto sampler working on front again.

I reinstalled the chemstation and the auto sampler worked fine on the front injector. I re-created my methods rather than bring the old ones back. When I went to rear this time I turn off the chemstation with the default method loaded. I turned off the auto sampler moved the plug to rear and moved the tower. I turned everything on ran a shot and turned the software and the auto sampler off and moved the plug and tower back to the front. I started chemstation and loaded my front injector method and again the auto sampler would not go.

I rechecked my method and everything is still like it should be for the auto sampler to be the injection method.

I am hope someone can help because it is driving me crazy.

I am using a HP5890 with a 7673 autosampler with Chemstation A.06.03.

We use this set up as well.

The Method has to be set up to use the autosampler. I think that's the first choice under "Instrument", and doesn't appear in the "Edit Entire Sequence" line-up.

The Method must be set for front injector, rear injector, or both, second choice under "Instrument".

The Sequence that is loaded must be compatible with the location of the autosampler that is set in the Method, see that under Sequence, Sequence Table, load the Sequence BEFORE you load the Method. You may need to load the def_gc.M first then laod up a sequence that has the location of choice, then load up your desired Method.

And of course the injector must be plugged into the appropriate socket on the control box, turning off the control box before removing/insering any of the cables.

I believe it's a software thing/a Chemstation thing. And have you re-booted????

Thank you for the reply Consumer Products Guy,


We have yet to set up a sequence so we are always using the default sequence. When I moved the injector around, the sequence automatically saw it in its new position.

I spent the last 90 minutes trying every combination of turning the the auto sampler off before/after load the front method, loading the default method, turning off chemstation, and rebooting the machine. Nothing worked. When I turned on the auto sampler it went through the start up sequence like normal no matter which port it was plugged into. The rear injector worked no matter how I switched back to it.

The methods are setup to use the auto sampler correctly. I am turning the controller box off before moving the cord.

When you switch between the front and rear, what is the order of events you do? If I am doing that correctly then it has to be some where else in the software, not the method or sequence, as reinstalling it "fixes" the problem.

With our 6890, we sometimes we have to reconfigure the instrument in order for it to recognize that we have moved the injector. Maybe this will work with your 5890.

On the front panel of the instrument, choose CONFIGURE, BACK INJECTOR, OFF. Then choose CONFIGURE, FRONT INJECTOR, ON.

Hope this works for you.
