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.
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
