Benefits

Ÿ Shimadzu have developed dynamic headspace methods for the analysis of EtO & 2-CE in spices
matrix. This method outperforms the current regulatory limits.
Ÿ Shimadzu’s GCMS-TQ8040 NX / GCMS-TQ8050 NX with liquid autosampler & dynamic headspace
sampler is complete tool for the analysis of EtO & 2-CE.

How to reduce acetaldehyde

§ Spices matrix have very high amount of acetaldehyde, and which may interfere with EtO in analysis.
§ So, to reduce acetaldehyde concentration from extracted sample solution, PSA is used as clean up
reagent
§ Amount (25 mg – 100 mg ) optimization is require as per the type of matrix
