TOF Tech Pars Company was established in 2011. The main aim of the company is to develop scientific instruments such as custom time-of-flight mass spectrometers (TOFMS) MALDI-TOF or ESI-TOF as well as atmospheric pressure ion mobility spectrometers (IMS) for industrial, government, and academic research labs. Our IMS is the only commercial instrument in the world that uses nonradioactive corona discharge ionization source, operates at high temperatures up to 230C and utilizes the novel inversed-pulse technique to enhance the resolution and sensitivity.
