ETP Electron Multipliers from SGE are incorporated as original equipment in every major quadrupole and TOF ICP-MS instrument being manufactured today. They deliver optimized ion and electronic optics and unique dynode shapes for maximum performance. The multi-dynode approach of all ETP Electron Multipliers result in longer lifetimes and better sensitivity compared with channel multipliers because of greater surface area. Increased surface area for enhanced sensitivity and extended operational life. Total compatibility with all major quadrupole, magnetic sector and TOF instruments.
