This is a post from a software company to those of you who would offer your advice and insight. Thanks...
We build an application that can capture ASCII data from a serial port and parse it into an ODBC database. It is a data capture utility and is not designed to provide control of GCs or composition graphs etc.
The application collects real-time and has an open filter/driver set where the user can specify what data segment is parsed into particular fields in the database.
Our original intention for the product was to read data from industrial GCs to make it available across an IP network or integrate it into a process database.
Do any of you have insight into a situation where this would be of value? Are there existing applications that do this? What are they/what do they cost? Any advice to us as we pursue this further?
Thank you for your input!
Chris

I may not quite understand your overall objective, however, I've written a GC program in LabVeiw that's a controller and captures data (ASCII or DAT etc) (with the insertion of a cheap GPIB board). I'm hooked up to a Network and share files to a select few ( Those who are allowed through my Firewalls).
I'm not sure I've helped in any way or told you anything usefull. If I have good and if not I've wasted my time

Chris,
Most GCs support a SIO port to exchange configuration, method, raw data, and status information with external computers. The trend, however, is towards ethernet and TCP/IP connections, for lots of reasons that should be obvious.
Most users look for an intgrated approach that not only records the GC detector data but also the status information, as well as controlling methods and configurations.
GC users seldom examine the raw data directly -- they want to view it graphically as a chromatogram (as you have noted). The raw data stream is analyzed by data handling software that detects and integrates chromatographic peaks to produce a database of retention information, identity information, and response information of various types. Especially in process GC, it is this reduced data set that's of interest.
A good place to look for information on commerical products is the LC/GC Magazine website buyer's guide, located by clicking on the top menu bar at http://www.lcgcmag.com
