SPME

Automated SPME

SPME technology in Extractables and Leachables studies with primery packaging material
The requirements of  authorities for Extractables and Leachables of primary packaging material have steadily increased. The analysis of Extractables & Leachables is normally done after extensive sample preparation by liquid extractions with HPLC-UV, HPLC-MS or GC-MS. This classic sample preparation is difficult to automate and is a persistent source of errors.
In addition, the high solvent consumption unnecessarily burdens the environment.
In order to optimize this process Analytical Services equipped its present State-of-the Arte equipment  with an additional micro extraction SPME (Solid Phase Micro Extraction) GC-MS system, an automated sample preparation method that works without a solvent.

 

What is SPME (Solid Phase Micro Extraction):
The extraction process occurs either in the gas phase or in the liquid phase of the sample using the coated part of the SPME needle. The desorption occurs without any intermediate steps in the injector of the GC System.

 

SPME-technique advantages:

  • no complex sample preparation (liquid/ liquid extraction)
  • no expensive extractions with  toxic organic solvents and subsequent concentration on Rotavopor
  • complete absence of organic solvents
  • direct sample analysis
  • no sample preparation errora by liquid extraction
  • no cross-contamination through different  solvents
  • SPME can be used for gaseous and liquid samples
  • automation of the entire process with suitable autosampler (high reproducibility)
  • time savings for routine analyses
  • ecological and sustainable technology
