Descrição

Nota de análise

In this application, SPME was used for the analysis of volatiles in limoncello using a headspace method. SPME is ideal for the analysis of aroma volatiles in flavored beverages such as liquors. A 100 μm PDMS fiber was inserted into the headspace of the limoncello sample for 30 minutes at 40 °C followed by GC analysis using FID detection. The SLB-5ms GC columns provide consistently low-bleed, inert, efficient, and durable separations.
