Top 6 Things You May Not Know About Gas Chromatography
1. The history of gas chromatography (GC) dates back to the first experiments of Mikhail Tsvet separating plant pigments using paper chromatography in 1903.
2. Schuftan & Eucken introduced vapor as the mobile phase in the 1930s.
3. German physical chemist Erika Cremer created the technique of gas chromatography in 1944.
4. Solid state gas chromatography was developed by German graduate student Fritz Prior in 1947. His work was overseen by Cremer.
5. English chemist Archer John Porter Martin, who built the foundation for the development of GC, created liquid-gas chromatography in 1950.
6. The XII Olympic Winter Games in Innsbruck, Austria used gas chromatography for rapid drug screening in routine testing of athletes.
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?
