AI Technical Summary

Technical Problem

Existing ion mobility spectrometers are susceptible to interference in complex atmospheric environments and have difficulty recovering quickly. They also suffer from decreased detection capabilities when contaminated with high concentrations of analytes.

Method used

It employs ion doping technology to alter the electron affinity potential of the ion source, shielding the ionization of analytes with low affinity potential. Combined with backflushing technology to clean the testing instrument, it is equipped with a heating device and hot air cleaning, optimized gas path design and heat dissipation structure, and uses lithium battery power and an OLED display.

Benefits of technology

It improves the sensitivity and anti-interference ability of the detector, shortens the self-recovery time, reduces management and procurement costs, and realizes miniaturized and portable detection.
