The gas chromatograph-mass spectrometer is a highly effective analytical instrument widely applied across various fields. As pollutants continue to increase, the significance of field monitoring and on-site analysis has become increasingly important. Therefore, the development of portable gas chromatograph-mass spectrometers is crucial for on-site analysis research. In this study, we present the instrumentation of a portable gas chromatograph system with built-in preconcentrator, enabling automated sample collection and improved sensitivity. The system operates from ambient temperature +3°C to 230°C, with a maximum ramp rate of 90°C/min, controlled via LabVIEW software. The portable gas chromatograph-mass spectrometer was employed to analyze fragrance volatile organic compounds emitted from perfumes. However, some fragrance volatile organic compounds cleavage during thermal desorption from preconcentrator. This is a crucial issue in environmental detection when using the thermal desorption tube. Furthermore, we discuss the potential of a portable gas chromatograph coupled with a miniature multi-turn time-of-flight mass spectrometer (MULTUM), a high-resolution and high-mass-accuracy portable mass spectrometer, to overcome certain limitations inherent to conventional portable gas chromatograph-mass spectrometer instruments.
