Chromatography
Applications of GC and GC/MS:
Many compounds can be determined by GC as can proved by their immense use in today’s. In general they must be volatile and stable at the temperature employed, typically from 5oC to 300 oC. But it is mainly useful for:
  
 All gases.
 Most ionized organic molecules, solid or liquid, containing up to about 25 carbons.
 Many organometallic compounds.
 
Chromatography
 
Gas Chromatography is commonly used for the following:
  
 Petrochemical analysis
 Environmental analysis
 Forensic analysis
 Drug analysis
 Food analysis
 Medical analysis
 Chemical industry
 Educational and Research
 
Applications of HPLC:
GC, because of its speed and sensitivity and quite broad applicability, has been more widely used since its development than the various modes of liquid chromatography. But the latter techniques have potentially broader use because approximately 85% are not sufficiently volatile or stable to be separated by GC. HPLC nowadays rivals GC in performance and allows separations and measurements to be made in a matter of minutes.
