Microchannel plate detectors
PHOTONIS' TruFlite microchannel plates and detector assemblies are designed for time-of-flight MS measurements. The plates' input surface reportedly reduces uncertainty in ion arrival time, or time jitter, and surface flatness is measured and controlled. According to the company, the pore size and bias angle are optimized to improve mass detection. The microchannel plates and detectors are available with 18-mm and 25-mm active areas.

LC–MS system
Agilent's 6150B series single-quadrupole liquid chromatograph–mass spectrometer is designed to provide higher sample throughput and can scan at 10,000 amu/s. According to the company, the system's sample inlet design uses superheated sheath gas to focus the ion stream entering the mass spectrometer, which provides a stronger signal with lower standard deviation at the limit of detection. The ionization technique reportedly enables efficient ionization for a broader range of compounds than electrospray or atmospheric pressure ionization alone.
