“…The main goal of this study was to obtain reliable information regarding the changes in volatile compound content during the process of ginger pickling without causing delays in the industrial workflow by using GC‐IMS. To obtain sufficient data from GC‐IMS, the time required from sampling to result communication must be reduced (approximately 40 minutes), and the stability and robustness of the method must be increased …”

“…The PCA was carried out using the software package SIMCA (version 14.1 Umetrics, Umea, Sweden) for chemometric elaboration. The fingerprint and PCA data were used to determine the dimensions of the data set and depict the original and processed ginger samples in 2D space while identifying the contributors to the differences detected between the original and processed ginger samples …”

“…In recent years, ion mobility spectrometry (IMS) has been recognized as an easy‐to‐operate, low‐cost, portable, and sensitive instrumental technique for the detection of volatile and semivolatile compounds in various matrixes . IMS offers fast analysis of analytes and low levels of detection (ppb) The technique relies on the gas–phase separation of ions under a weak electric field at ambient pressure The migration velocity of the ions depends on their shape, size, structure, and the spatial distribution of their internal electric charge.…”

Pickled ginger is a popular traditional Chinese pickled food. Analysis of the volatile compounds in pickled ginger is critical for guiding production, achieving a high level of sensory quality, and maintaining a healthy diet. Ion mobility spectrometry (IMS) with gas chromatography (GC) offers a fast, sensitive, and efficient tool for detecting volatile compounds. Herein, the headspace GC‐IMS method was used to detect the volatile flavour compounds produced during the pickling of ginger. The ion mobility data were continuously processed using the principal component analysis (PCA) and fingerprint chart methods. Based on the analysis of fresh ginger, pickled ginger, and soy sauce, two main components accounted for 58% and 27% of the total variance. During pickling, the heptanal and heptanone contents decreased, while the contents of butanal, butanone, and methional increased, as determined from the GC‐IMS fingerprint, resulting in changes in the flavour of the pickled ginger. The GC‐IMS method was efficient, convenient, and useful for the detection of volatile flavour compounds produced during the ginger pickling process.

An analytical method based on dispersive solid-phase extraction with a multiwalled carbon nanotubes sorbent coupled with positive pulse glow discharge ion mobility spectrometry was developed for analysis of 30 pesticide residues in drinking water samples. Reduced ion mobilities and the mass-mobility correlation of 30 pesticides were measured. The pesticides were divided into five groups to verify the separation capability of pulse glow discharge in mobility spectrometry. The extraction conditions such as desorption solvent, ionic strength, conditions of adsorption and desorption, the amounts of multiwalled carbon nanotubes, and solution pH were optimized. The enrichment factors of pesticides were 5.4- to 48.7-fold (theoretical enrichment factor was 50-fold). The detection limits of pesticides were 0.01∼0.77 μg/kg. The linear range was 0.005-0.2 mg/L for pesticide standard solutions, with determination coefficients from 0.9616 to 0.9999. The method was applied for the analysis of practical and spiked drinking water samples. All results were confirmed by high-performance liquid chromatography with tandem mass spectrometry. The proposed method was proven to be a commendably rapid screening qualitative and semiquantitative technique for the analysis of pesticide residues in drinking water samples on site.

A method for the determination of organic chlorides in hydrogen for fuel cell vehicles by gas chromatography coupled with ion mobility spectrometry was established. Organic chlorides were separated by a non‐polar gas chromatography column and detected in the negative ion mode of the ion mobility spectrometer. The effect of operating parameters of ion mobility spectrometer including drift gas flow rate and drift tube temperature on sensitivity and resolution were evaluated. Under the optimized conditions, the detection limits of seven organic chlorides were from 0.65 to 6.73 nmol/mol, which met the requirement of detection for the specification limit of 50 nmol/mol of total halogen impurities in hydrogen for fuel cell vehicles. Compared with gas chromatography‐mass spectrometry, and gas chromatography coupled with electron capture detector under the same gas chromatography conditions, gas chromatography coupled with ion mobility spectrometry method demonstrated higher sensitivity for detection of organic chlorides under study. Based on the portability of the device and its detection capabilities, gas chromatography coupled with ion mobility spectrometry has the potential to perform online detection of impurities in hydrogen for fuel cell vehicles.
