Application and development trends of gas chromatography–ion mobility spectrometry for traditional Chinese medicine, clinical, food and environmental analysis

Characterisation of Flavour Attributes in Egg White Protein Using HS-GC-IMS Combined with E-Nose and E-Tongue: Effect of High-Voltage Cold Plasma Treatment Time

“…Gas chromatography spectrometry has been used extensively to discriminate aroma components of various egg proteins, such as GC-MS for an egg yolk [ 32 ], SPME-GC-MS for egg yolk [ 33 ], HS-SPME GC-MS for egg white, and GC-O/GC-MS for egg yolk [ 34 ] proteins. GC-MS has an excellent discrimination capability, but it needs a high-vacuum working setting which restricts its mobility, additionally, it’s time consuming because it needs a lot of continual steps which reduces sample characterisation efficacy and hinders rapid identification of compounds [ 35 ]. GC-IMS however is an inexpensive and easy to operate device that uses gas phase separation and detection techniques by integrating the discrimination capability of GC with its fast, highly sensitive detection technique [ 36 ].…”

“…GC-IMS however is an inexpensive and easy to operate device that uses gas phase separation and detection techniques by integrating the discrimination capability of GC with its fast, highly sensitive detection technique [ 36 ]. IMS is an analytical method for identifying volatile and semi-volatile compounds that uses a low electric field to separate the generated ions in the gas phase at atmospheric pressure [ 35 ]. Likewise, electronic nose (E-nose) has also been used to assess foods’ aroma and other attributes due to its being inexpensive and non-destructive [ 37 ].…”

Discrimination and Characterization of the Volatile Organic Compounds in Schizonepetae Spica from Six Regions of China Using HS-GC-IMS and HS-SPME-GC-MS

“…At present, the most common used technologies for the comprehensive characterization of VOCs include gas chromatography-mass spectrometry (GC-MS), two-dimensional gas chromatography (GC×GC), gas chromatography olfactory determination mass spectrometry (GC-O-MS), and electronic nose (E-nose) [ 9 ]. GC-MS is being widely used in the analysis of VOCs, which has high-efficiency separation of gas chromatography and high resolution of mass spectrometry, but it has the drawback of cumbersome treatment before sampling and higher cost [ 10 ].…”

Correlation between the redox activity of Polygonum multiflorum extract and its extraction technology with Chinese liquor (Baijiu): An electrochemistry-based study

“…Traditional Chinese medicine (TCM) culture has a history of thousands of years and is a crucial cultural heritage of humankind [ 1 , 2 ]. For example, artemisinin is a Chinese medicine developed on the basis of modern approaches and theories that can efficiently reduce the mortality of malaria, representing a crucial example of the modernization process of TCM [ 3 , 4 ].…”
