I am looking to purchase Alltech ELSD to hook up with my Agilent LC 1100 which is run with Chemstation 10. Both Agilent & Alltech had both provide me with different parts to purchase to hook them up.

Anyone had any experience on the parts to buy?

Well, I'm close here, I've got Agilent 1100 system with Chemstation A.09 and the Alltech ELSD 2000. Our Chemstation talks to the computer using a LAN system, not a GPIB board. We have an Agilent #35900E analog/digital converter which digitalizes the ELSD signal, which is collected on the computer and all the routine Data Analysis stuff is the same. It works fine, relaible, no issues.

Thanks alot! Really appreciate your reply.

Agilent quoted me 6 items:
1. Dual-channel A/D interface box -- Agilent Part 35900E (which u have)
2. General Purpose Signal Cable -- Agilent Part 35900-60630
3. General Purpose Remote Cable -- Agilent Part 35900-60670
4. TCP-IP LAN MIO board for Host Communication -- Agilent Part 35900 OPT
5. Chemstation software for additional A/D (Software module to add control of and data acquistion from 35900 converter and autosampler) -- Agilent Part G2073AA
6. Computer Hub for interfacing more than 1 instrument to a PC

Alltech mentioned about the following:
7. BCD Contact Closure Board -- Agilent Part PN G1351-68701
8. BCD Cable -- Agilent Part PN G1103-61611

Not sure if I need to purchase them. Hope you could advise me. (Also have Chemstation Revision 9)

Thank you.

I can try to help you more if you can wait until I get back to the office next week, as I doubt I'd be going in today through Tuesday. I'm not really a computer guy, but off memory, yes, you'd need a signal cable from the 35900E to the ELSD. Ours ELSD takes two bare wire or spade terminals for the signal, and the plug that goes into the 35900E is the same as used on the old 3396 type integrators, so you could cut off the other end and strip the wires there if you have one of those.
The HPLC autosampler module has an upgrade (if you don't have it, sounds like the BCD Contact Closure Board -- Agilent Part PN G1351-68701 and BCD Cable -- Agilent Part PN G1103-61611) for about $350 which controls the contact closures of things like your ELSD; this can be used to autozero at the beginning of each injection, etc., if desired. Yes, there's a computer "hub" which I got at CompUSA and was cheap. I don't know about the Chemstation software for additional A/D (Software module to add control of and data acquistion from 35900 converter and autosampler) -- Agilent Part G2073AA; I don't think any of our three Agilent HPLCs using A/D have this. As to the TCP-IP LAN MIO board for Host Communication -- Agilent Part 35900 OPT - I do remember something about TCP when I re-loaded the software, but I don't know exactly what it does; we originally had Chemstation A.07 and GPIB communications with this (I think with an internal A/D board), but had to upgrade to A.09 to use ChemStor data security system, and the engineer changed it over to LAN communications when he upgraded to A.09 and a non-HP computer.

Thanks a lot for the information.

Awaiting more information from you on Tuesday.

Thanks so much!

Unfortunately, I don't know if there's a way for me to tell if our system does have G2073AA. I do know that in Chemstation Configuration Editor, mine lists, for a LAN system:

1100 system
1100 System Access IP:10.1.1.101
Dual Channel Iface
35900E - 2 Channel IP:10.1.1.103
