GC systems with ChemStation are being decommissioned. Stored data needs to be kept and accessible for 10 years without having maintained the original system.
The only thing I've found for Agilent ChemStation is some sort of a user guide where various technologies and operations are presented. I suggest you download the user guide on your computer to see exactly what I'm talking about. Keep in mind that you also need a PDF reader to be able to open the file. Luckily, there are plenty to choose from.
