Scientific Breakthrough |
The high-resolution linear TOF mass spectrometer is designed using the comprehensive calculation model pioneered by our group. Big data analysis reveals true optimal conditions of TOF instruments. The key advancements here are the new ion source dimensions, electric field,precise timing control. It overcomes the limitation in conventional designs that higher spectral resolution is available only with long mass analyzers. We have achieved high resolution with optimized short analyzers. The instrument offers better sensitivityresolution in high mass range due to low ion loss.

Industrial Applicability |
Mass spectrometry is indispensable in analytical science with fast growing global demand. Small size, low cost, sensitive,high resolution are potentials of our instrument to replace its conventional counterparts. The wide mass rangeportability could help to develop various applicationsresearch topics. We plan to commercialize this designto promote its applications in clinical identification, pharmaceutical development, food safety,material analysis, including the screening test of bacterial pneumonia.
