Enhancing SPME analysis of foods and beverages with cryogen-free trap focusing
Application Note 289
Enhancing aroma profiling of foods and beverages with cryogen-free trap focusing
Solid-phase microextraction (SPME) Arrow is a popular tool for profiling food and beverage aroma, but direct desorption into the GC inlet can result in poor peak shape and missed compounds.
This application note demonstrates how coupling SPME Arrow with cryogen-free trap focusing on Centri® sharpens peaks, improves sensitivity and enhances identification of key aroma-active compounds.
Cola drink and garlic powder are used to illustrate the benefits of this technique, including improved detection of trace-level volatiles and analysis across a wider concentration range.
Key benefits
-
Sharper peaks and improved compound identification through cryogen-free trap focusing
-
Enhanced sensitivity for detecting trace-level aroma compounds
-
Expanded analyte coverage using multi-step enrichment (MSE®)
-
Simplified analysis of both high- and low-concentration compounds using High/Low re-collection
