Introduction

SIM-MAX LSA3000 is a ultra-low level liquid scintillation spectrometer,which was independently developed by Shanghai SIM-MAX Technology Co.,Ltd. It is used for detection of ultra low level of beta and alpha radiation. 

Its technical performances and parameters have entered into the international advanced level and 

filled the demestic blank in ultra low level liquid scintillation spectrometer instrument. 

SIM-MAX LSA3000 which is a necessary equipment in the low level radioactive measurement laboratory, 

is mainly used for measurement of low level 3H or 14C from environmental samples(such as: water, 

air, land, animals and plants)and other alpha and beta nuclides radiation. Applications range from 

drinking water analyses of radon, food control for 90Sr, radioactive effluent measurements at nuclear 

power plants, emergency preparedness for nuclear power and homeland security, radiocarbon dating,  

ocean expedition to other biobased material analyses.

 

Features:  

n Adopt the Triple to Double Coincidence Ratio method (TDCR), no inherent gamma source

n Used for both relative and absolute activity measurement 

n Counting and spectrum analysis

n Dual multi-channel analysis technology

n TDCR and Efficiency Tracing Technique are used for double labelling separation

n Automatic continuous spectrum stablization

n Auto-change sampling; once for 30 samples

n Convenient measurement and data analysis with two display screens

n Excellent data processing function, automatically or manually calculate pulse shape area,counting 

rate and detection efficiency

 

Applications：

l Radioactive effluent measurements at nuclear power plants

l Environmental-Natural and Man-made radioactivity 

l Nature radiation detection of envrionment

l Water analysis

l Food control(such as, ⁹⁰Sr)

l Radiocarbon dating

l Measurement and quality supervision

 

l Biochemical research
