LSC3000 Ultra Low Background Liquid Scintillation Spectrometer

Ultra Low Background Liquid Scintillation Spectrometer

Product introduction           

• LSC3000 ultra-low background liquid scintillation spectrometer is a liquid scintillation analyzer independently developed for the determination of ultra-low-level α and β-emitter radioactivity. Its technical performance and index parameters rank among the international advanced ultra-low levels The ranks of liquid scintillation spectrometers have filled the domestic blank.

• LSC3000 ultra-low background liquid scintillation spectrometer is an essential equipment for low-level radioactivity measurement laboratories, mainly used for extremely low levels of 3H, 14C in environmental samples (such as water, air, soil, animals, plants, etc.) It can also be used for the measurement of other α nuclides and β nuclides, and is widely used in nuclear power plants, nuclear energy facilities, environmental protection, education, scientific research, hydrogeology, food science, archaeological dating, and ocean expeditions.

Features

• Using TDCR quenching correction technology

• Using dual multi-channel analysis technology, providing a unique measurement and analysis program for α and β in water

• Direct measurement of high energy beta nuclide activity using Cherenkov radiation technique

• Absolute measurement technology combined with efficiency tracking technology for dual label separation

• Coexistence of relative and absolute measurements, eliminating the need for standard source calibration
