Accelerated time-of-flight mass spectrometry

We employ a simple modification to the conventional time of flight mass spectrometry (TOFMS)where a variable and (pseudo)-random pulsing rate is used which allows for traces from different pulses to overlap. This modification requires little alteration to the currently employed hardware. However, it requires a reconstruction method to recover the spectrum from highly aliased traces. We propose and demonstrate an efficient algorithm that can process massive TOFMS data using computational resources that can be considered modest with today´s standards. Our approach can be used to improve duty cycle, throughput, and mass resolution of TOFMS at the same time. We expect this to extend the applicability of TOFMS to new domains.
