The detector is based on a 512x512 active pixel array, operating in parallel acquisition mode. Each pixel has its own dedicated electronics and registers individual ion arrival times digitally. This enables measurements without electronic noise, increases sensitivity and extends mass range. In addition the IonPix camera provides fast mass spectrometric imaging capabilities with high spatial resolution. The detector turns a single ToF--‐MS system into more than a quarter million parallel ToF--‐MS systems. The detector can be retrofitted to any standard 4” DN100CF flange. The image shows a peptide/matrix sample covered by a 37μm pitched grid with ~500nm pixel sizes (Soltwisch, J. 2013).
