Gas chromatography (GC) was at one time commonly called “GLC,” where the “L” stands for liquid. Inside GC columns are particles of a ceramic or inert material coated with an extremely viscous liquid stationary phase that interacts with the analyte. By contrast, HPLC stationary phases are bonded to the base material. GC is a common technique used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition.
Top 6 Questions You Should Ask When Buying a GC System
1. 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?
2. What differentiates the vendor’s GC system from others offered, in terms of performance?
3. How do you validate the specification claims presented by the vendor?
4. Has the data processing software been designed for enhanced analytics, with workflow in mind and does it support critical compliance requirements?
5. What are important price points to keep in mind when selecting a GC system?
6. Laboratories need fast and effective services, including an effective distribution of instruments, spare parts, education, and service personnel. How does the company serve these needs worldwide?
