Heyo! I'm trying to connect a Polymer Laboratories PL-ELS 2100 ELSD detector up to an Agilent 1200 Series Lan-based HPLC running ChemStation B.04.03-SP2. The detector has no drivers or firmware with it.

It seems like in order to get the output from the detector we would need an analog to digital converter (35900E A/D) as it is an older ELSD. However, from what I've read I still should be able to send the detector instructions via RS232 cable from ChemStation but I haven't had any luck.

Any help or thoughts would be appreciated. Additionally, do you know what connectors we might need in order to eventually connect it to the A/D converter and would we need an A/D license for ChemStation?

Thank you so much for your help and time.

I only had experience with 1050 and 1100 series and external detectors (conductivity, ELSD) and Revision A software, and we did use 35900E A/D box. The 35900E connected to computer and had a signal cable and remote cable connected to the detector.

Any help or thoughts would be appreciated. Additionally, do you know what connectors we might need in order to eventually connect it to the A/D converter and would we need an A/D license for ChemStation?

I cannot remember whether we had a separate license for the 35900E......

Hello good morning,
I find myself in the same situation you were in, I try to connect a PL-ElS 2100 with a 1200 tower. My current problem is that I tried to change the ELS 2100 firmware but the last firmware was erased and not charged de new so at this moment my detector doesn´t have firmware.

Does anyone know what can I do?

I appreciate any help

Hi all!

We have been dealing with a "bricked" PL-ElS 2100 recently.
Luckily we could find the firmware and tools to bring it back to life. We got it connected to a Agilent system with OpenLab and works perfectly!

We can help get your ELSD back online! And many others HPLC/GC/MS related instruments!
