CSS Analytical handles a large volume of calls for support on HP and Agilent GC/MS systems. As support for these older systems is getting harder to find we continue to lead the field in support for these older HP GCs and Mass Specs. 

In addition to parts and repair, we offer a list of upgrade solutions to make your instrument newer, better and faster  CSS Analytical Upgrades .

CSS Analytical offers FREE phone support via our toll free "800" number to our current warranty customers and customers with service contracts.

If you are not a current customer, or it has been a while since your last purchase please feel free to email us your support question. We're very good at responding quickly.   Also, you may be interested in checking out our blocks of "pre-paid" service hours giving you direct access and quick response by phone and/or email.

If desired, we can repair your instrument or component with "At our Lab" repair. 

Before you contact CSS Analytical for any support needs you might have, please complete our "Basic Questions" form so that we might serve you more effeciently.

CSS Analytical can repair your GC, HPLC or MS system, or component at our repair lab, test it and return it to you. Visit our "At our Lab Repair" page.  We have many spare parts in stock and offer an attractive bench repair rate of only $150 per hour.  Factory repair is a very cost effective way of system repair. Fedex charges are much less expensive than air plane trips to your site. Parts can often be repaired and returned to you much faster than it would take to set up a visit on site.
