Laboratory Analysis Instruments

Low Level Liquid Scintillation Spectrometer

Features:

n Adopt 3+3 coincidence-anticoincidence detection technology and the Triple to Double Coincidence Ratio method (TDCR)

n Adopt double multichannel analysis technology to realize high resolution linear spectrum analysis through gain switching

n The usage of Cerenkov-counting can directly measure high energy beta radioactivity

n Use rack to exchange samples, maximum accommodation of 260 standard 20ml bottles

n Software running in Windows, directly controls processes of testing, analysis and storage

n Humanized structure of the program card, several experimental measurement parameters can be set each time

n With functions of half-life calibration, quenching calibration, background deduction, etc

n Configured with stable and reliable binary encoding and reflective sheet to recognize, for convenience of sample tracking
