Flying to new destinations : Instrument modifications, which give three detection areas (see scheme) in a two‐channel detection scheme, extend the achievable duty cycle of a Hadamard transform time‐of‐flight mass spectrometer (HT‐TOFMS) to 100 % and effectively converts TOFMS into a continuous detection technique. Beyond the improved signal‐to‐noise ratio, this advance gives an increase in the data‐acquisition rate leading to a higher detection speed.
