My company is looking to move away from lab based GC and implement new at-line GCs onto our chemical facilities. They will be used to monitor halogenated impurities in refrigerant products. Can anyone recommend vendors who can provide these instruments and also who offer excellent support. How much does a typical at-line GC cost?
Thanks in anticipation..Paul

Varian has a nice system called the 4900 Micro GC that can be used for at- / on-line applications.

Process analyzers cost $30,000 and up to over $100,000, depending upon the application.

There are many vendors who work with Varian, Agilent, and Perkin Elmer instrumentation. These are easy to service. The real problem is the sample system.

Get quotes from the major vendors: AAB, Siemens AAI, Yokagowa, Daniel, and the above mentioned but unnamed 3rd party vendors (Arnel and Wasson come to mind, but there are others).

Process analyzers can save a lot of money over time but the initial investment and learning curve can be expensive at first.

Thankyou for your replies - much appreciated. I'm getting quotes from Varian, Agilent and Unicam (ThermoOnix). Regards, Paul.
