Resolution-optimized headspace gas chromatography-ion mobility spectrometry (HS-GC-IMS) for non-targeted olive oil profiling

Analytical and Bioanalytical Chemistry, 2017
A prototype gas chromatography-ion mobility spectrometry (GC-IMS) system, hyphenating temperature-ramped headspace GC to a modified drift time IMS cell, was evaluated and compared to a conventional, isothermal capillary column (CC)-IMS system on the example of the geographical differentiation of extra virgin olive oils (EVOO) from Spain and Italy.

Development of a flavor fingerprint by HS-GC–IMS with PCA for volatile compounds of Tricholoma matsutake Singer

Food Chemistry, 2019
The flavor fingerprint of Tricholoma matsutake Singer was developed and volatile compounds were investigated by HS-GC-IMS fingerprinting combining with PCA. A total of 25 typical target compounds were identified. The differences of flavor compounds in pileus and stipe of Tricholoma matsutake Singer from different areas were observed.

Investigating the Components Change of Steamed Corydalis yanhusuo via Mass Spectrometry Imaging, HS-GC-IMS, HPLC, and Network Pharmacology to Unveil Mechanism for Antichronic Atrophic Gastritis.

Biomedical chromotography
Corydalis yanhusuo (YHS), a traditional Chinese medicine (TCM), was commonly steamed before clinical usage for chronic atrophic gastritis (CAG). However, the reasonable steaming time had not occurred, and bioactive components of potential mechanisms of ...
