Two dimensional gas chromatography time-of-flight mass spectrometer

Four nozzle modulator: alternating cold focusing and thermal desorption, with variable modulation period. This design has obtained a national patent;

Optional consumable modulator or high-performance liquid nitrogen modulator;

Independent temperature control column box: The gas chromatograph adopts a dual column temperature box design, with two chromatography columns independently controlled for temperature, eliminating temperature interference during two-dimensional chromatography column analysis. The modulator is located in the second column temperature box to eliminate the interference of modulation temperature switching on peak retention time, and the chromatographic column is easy to install;

Time of flight mass spectrometry: dual filament structure,EIIonizing source (standard available)EISpectrogram),Using a high-speed data acquisition card, the acquisition speed reaches500 scans/secThe frequency of rejection is higher than15KHz）And easy to maintain, truly achieving no compromise between high acquisition rate, high sensitivity, high resolution, and high quality accuracy;

Integrated software system: unified design of instrument operation control, data acquisition, and data processing, vacuum protection, automatic instrument tuning, automatic spectral library retrieval for qualitative analysis, and automatic quantitative analysis.
