gaschromatographe control by labview

I want to acquire data and control a gc (gaschromatographe) with labview. These gc's are: Interscience, Delsi Nermag, Hewlett Packard
Chrompack, Varian.
There are no Labview drivers available from these manufacturers.
Most important is to acquire data from the GC.
Controlling of the GC is an option, but less important than acquiring data from the GC.

Hi,

I'd go the old fashioned A/D route with a A/D board to get just the
data from an analog output port. The problem is finding the right
point on the printed circuit board and accessing it without voiding
waranty. Add a DIO for the start button and you've all you need.

I'd leave setting parameters to the vendor supplied programs, as you
won't get spec's for the d
ifferent protocols.

One A/D board with a handfull of channels and "low" sampling rates
should suffice.
