5, Basic Working Principle

  The detector employs next-generation ion mobility spectrometry technology, as illustrated in Figure 1.2.1. When the sample molecules undergo thermal desorption through the injection system, they enter the ionization zone of the ion mobility tube via the injection channel and are ionized by a non-radioactive ionization source. The ionized molecules transform from neutral to charged ions. These charged ions then pass through the ion gate-controlled reaction zone into the ion mobility region, where they travel under a uniform electric field to the ion reception zone, where they are converted into electrical signals. The weak electrical signals are amplified by an amplifier and transmitted to the data processing system, ultimately forming the detection spectrum of the ion mobility spectrometry.

Figure 1.2.1 Ion Migration Spectrum Working Principle

  The mass-to-charge ratio (m/z) of ions formed from the tested sample molecules varies, resulting in different collision cross-sectional areas. Consequently, ions exhibit distinct migration rates within the migration zone, leading to varying arrival times in the reception zone. Ion mobility spectrometry leverages these differential migration rates to identify specific sample components.
