2013 Gas Chromatography Product Survey Results

By Lab Manager

Gas chromatography (GC) is a common technique used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. GC is typically used for separating the different components of a mixture, improving the purity of a particular substance, or identifying a particular compound. GC is a ubiquitous technique, and the various GC instruments available are designed to achieve every requirement of the technique.

6 Questions to Ask When Buying a GC System

What factors come into play when determining the GC system specifications you require in terms of cycle time, enhanced operator benefits, increased productivity and flexibility for specific applications

What differentiates the vendor’s GC system from others offered, in terms of performance?

How do you validate the specification claims presented by the vendor?

Has the data processing software been designed for enhanced analytics, with workflow in mind and does it support critical compliance requirements?

What are important price points to keep in mind when selecting a GC system?

Nearly 45% of respondents plan on purchasing a new or additional GC system in the next year. The primary reasons for these purchases are:

Addition to existing systems, increase capacity
Upgrading existing GC-MS system
Require more sensitivity
Require higher quality data
Setting up a new lab
Require shorter run times/increased lab throughput
Other reasons
Trying to reduce operating costs
Require greater mass stability
