Alltech 800 ELSD - HP1050 Chemstation

[ghum@sialco.com]

Can anyone get me started (and hopefully finished) on the following setup:

We are giving a second life to a HP1050 system which is run by Chemstation. We want to hook up an Alltech 800 ELSD which we also inherited. I am sure that someone out there has done this and it comes down to whether or not they see this post. We have an HP35900 Interface so it comes down to what are the right connections and cabling. I am thinking:
- [Alltech800 analog out] to [analog in on 35900]
- [35900 HPIB out] to [HPIB stack on 1050]

Should I also use the 9 pin remote cables and if so to and from what?

Any hints and suggestions are welcome.

Yep, I've got a similar set-up. You don't state whether your 35900 is a 35900D internal circuit board that goes in the computer or a 35900E external box.

35900D: I've never been able to get a 35900D to work with Windows newer than Windows 95, but I'm not so good at computers. Attach a signal cable to your detector. Attach the 9-pin remote from Remote "A" on the 35900D to the 1050 stack (important). Go into ChemStation Configuration Editor and scroll down and add the 35900D module, click Add. Enter your 35900D select code (typical is 6, or whatever you've selected with the dip switches), then click on both "A" and "B", then OK. Save the Configuration.

35900E: I've used with Windows 2000. Piggyback HPIB cable from back of computer to the 35900E. Attach a signal cable to your detector. Attach the 9-pin remote from Remote "A" on the 35900E to the 1050 stack (important). Go into ChemStation Configuration Editor and scroll down and add the 35900E module, click Add. Enter your 35900E select code, then click on both "A" and "B", then OK. Save the Configuration.

If you want to use external event switch to zero detector, that's under "More Injector" and I believe "More Pump" under Instrument, but you'll need the special reddish-brown connectors that go on the back of those modules.

Thanks for the reply.

I am still having trouble and not sure where it is coming from. I used the HP configuration editor and entered the 35900C, selecting Channel A and GPIB address of 13. The 800 is attached via the signal cables to the 35900. The 35900 is attached to the computer via the GPIB cable (along with the pump, DAD and autosampler). The remote from the 35900 is attached to the remote connection of the pump (not sure if this would make a difference).

I know the ELSD is sending out a signal. The Chemstation software says it cannot communicate with the 35900 - it asks that I make sure it is powered on (it is) and to check the GPIB address (13) and select code. I am not sure where to set the select code.

Any further advice and ideas are always welcome.

What version of Windows? What version of ChemStation? Is 35900C internal or external, haven't had experience with that.

HPIB address/GPIB address/select code are all the same. Your box or circuit board has little DIP switches which identify its code.

We are running Chemstation for LC 3D (Rev A.09.01 [1206]) on Windows 2000.

The 35900 C is an external box - to my understanding, it is similar to the 35900E but cannot be connected via LAN. I have begun changing the GPIB on the back and matching it with changes in the Configuration Editor. I am beginning to wonder if sequence of GPIB connections and/or remote capables have an effect. I am trying to run a DAD and the 35900/ELSD in sequence... I might have to drop the DAD.

Beyond that, I do not think I need to go into I/O config and VISA assistant... I shall continue to forge ahead but your experience is greatly appreciated.

we attached our Alltech 3300 ELSD to out Agilent 1100 with chemstation and didnt use a 35900 box, everyone including Agilent support told us it was impossible - it is possible, we did it alongside the help of our "Speck & Burke" engineer support contract they were wonderful. We ended up using a simple LAN connection and currently have it up and running in our lab.

Check the IP address on your actual ELSD isn't competing for the same IP address as your PC, this was one of our main issues and we had to call it "blah blah.02" and the agilent "blah blah.01" (please dont take me literally with the blah blah bit lol!) to get them to work beside each other, the setting on the actual ELSD have to match the configuration editor on the PC or it will say it cant find it. We had a bit of a nightmare so I feel your pain but we got there in the end. Agilent support as well should be able to talk you through the connection if you explain the issue as you're using all the official kit (unlike us lol)

p.s. I checked we used the ELS1 channel.
