Soft ionization technology - generates protonated molecular ions of the analyte without producing fragmented ions,

Soft ionization technology - generates protonated molecular ions of the analyte without producing fragmented ions
Injection device: The injection tube is responsible for introducing gaseous target substances into the molecular ion reaction chamber.
Ion source: The commonly used design is to discharge water vapor using a hollow cathode, producing high-purity H3O+ions.
Proton transfer reaction zone (drift tube): The pressure, temperature, and electric field in the drift tube ensure that the reagent ions separate the analyte in a stable microenvironment.

Proton transfer reaction time-of-flight mass spectrometeradoptSoft ionization mass spectrometry technology, is a direct reading analysis method that uses gas-phase hydrated hydrogen ions as reagent ions for ionization.

The main functions are as follows:

①Real time monitoring of hundreds of volatile organic compounds present in the air，Volatile organic compounds such as alkanes, aromatic hydrocarbons, aldehydes, ketone alcohols, etc;

②No need for pre separationNo sample preparation required, resolution can reach 8000，Outstanding performance，The results are accurate and reliable;

③Based on chemical ionization mass spectrometry，traditionalGCMS has many advantages compared to others，Can provide real-time non-standard quantitative analysis;

④Due to low proton affinity,H₃O⁺Ions do not react with any major components in clean airVery sensitive to trace gases in the sample gas;

⑤No need to prepare samples before measurement（For example, pre concentration or chemical separation procedures），Therefore, the all air sample can be directly introduced into the drift tube，Thus achieving dynamic measurement;

⑥Based on lightweight framework and structural design，It can be easily placed in passenger cars or mobile measuring vehicles. Great flexibility in space，Almost able to move and operate in environments with limited space;

Proton transfer reaction time-of-flight mass spectrometerwidely used inFields such as environmental research, food and flavor science, petrochemical applications, chemical analysis, security and explosion prevention, biological research, medical research, etc.
