Agilent HPLC manual injector

[1100NZ]

I have an Agilent 1100 HPLC and I've just bought a Rheodyne 8125 manual injector.

My problem is that I can't get it to send the start signal to the Chemstation software. I'm new to Chemstation, and I've been looking for a setting that tells it to look for a manual injection, but can't find anything.

I don't have the factory cable - instead I've made a cable up that hooks into the APG port with a BNC connection. The position sensor has been checked and is open circuit in "load" and closed in "inject", right up to the connector.

If someone can help, I would greatly appreciate it.

Is this a software setting problem, or a hardware problem?

Thanks

Hello

Please follow instruction below:

1.Go to “method and run control” mode in Chemstation
2.Go to: “Instrument” – “More injectors” and click “use external injector” (you should see mark symbol next to it "✓")

When you start your run Chemstation status will be “pink – waiting for injection”. Of course you need remote cable to connect external injector device with LC module. Otherwise you won’t be able to trigger your LC automatically.
