waters HPLC

[stflock]

Anyone got an NI driver for a Waters 2795 HPLC and 996 photodiode array detector?

I have the drivers for a HPIB card but I do not know how to convert it so GPIB cards will work. I would pay $3000 if anyone could make a standard HP GPIB card work with the waters Empower software and on the HPLC's!

HPIB and GPIB are synonymous - especially if you are using a controller from HP. If you want the code rewritten to so that either an HP or NI controller could be used, you would want to use VISA.

You might want at least mention the programming language you are using.

I just realized that you might be asking about something other than an instrument driver that is normally the subject here.

If you are looking for a low level hardware/windows driver for an HP card, then you have come to the wrong place. NI does not make HP controllers - HP does and NI does not write drivers for HP cards - HP does.

Yeah I dont know anything about cards. Even if it is a NI card, if it worked in acquiring data from a Waters HPLC which have HPIB out and sent it to Empower software which is the Waters software (http://www.waters.com/waters/nav.htm?locale=en_US&cid=513188) , It would work for me. Its just because the Waters HPIB cards are hard as hell to find and cost over $1000 used, $5000 new but the NI, Agilent, HP ones are everywhere.

I have not been able to find anything on that site about the GPIB card they use. If it's a standard pc that it's in, it would seem strange that they would design their own GPIB controller but stranger things have happened. You could remove the card to see if there are any markings to identify it as coming from someone else.

If it is truly proprietary, then I doubt you will be able to replace it. While the GPIB communication from the controller to the instrument will obey the standard, that does not mean that the interface between the program and the controller will be any sort of standard. It would be a custom driver for the OS and the program would be using custom function calls to that driver.
