ROBOKROM AUTOINJECTOR - PT. RAFA

 

ROBOKROM AUTOINJECTOR

WHEN DO WE USE HEAD SPACE?

  • When direct injection is not possible.
  • When results are better than direct injection (depends on compound/matrix).
  • Samples that need a previous extraction (alcohol inblood, water pollutants, etc.).
  • When analyzing only volatile compounds (food, beverages, perfumes,…).

Advantage

  • The non volatile compounds are not introduced in the GC System.
  • Better sensitivity.
  • Sample preparation is not needed.

Disadvantage

  • Quantification is done only in the vapor phase.
  • Quantification problems (internal standard).
  • Special equipment.
