| One routine task for analytical laboratories in the Petroleum or Petrochemical industry is the analysis of high purity chemicals. Current analytical methods must resort to manual injection with individual syringes dedicated for each chemical, or automatic instrumentation dedicated to a single product or chemical because of this carryover problem.
There are many requirements that must be satisfied to successfully use an autosampler for Gas Chromatography and reduce carryover to acceptable levels, but an automated instrument can successfully be used for multiple high purity chemicals. |
