The patented High Mass BiPolar Time of Flight detector improves the detection efficiency of very high mass ions with significantly less complexity and expense when compared to other high-mass detection solutions. It is ideal for Matrix-Assisted Laser Desorption Ionization Time of Flight (MALDI TOF) applications.","The detector is comprised of a high-sensitivity microchannel plate, a high-speed scintillator, and a photomultiplier which can detect both positive and negative ions with 30 kV isolation. This innovative solution also features a gridless optic system that provides high sensitivity detection for masses in excess of 100 kDa. The compact shape and simplified detection system supports many high mass operating modes without the need to manipulate the detector through the ion beam. The detector provides uniform fields that allow for simultaneous space and velocity focusing and can detect both positive and negative ions. Its fast rise time – <1.2ns FWHM – make it an ideal solution for sensitive high mass detection in a wide range of instruments and applications.
