Application

Core technology

Tri-Carb 4810TR

Tri carb 4810tr liquid scintillation counter can be used for basic research, CPM and direct DPM applications.

Tri-Carb 4910TR

It is an ideal LSC system suitable for more complex research applications and needs DPM counting measurement. It has various functions and can be used for environmental applications after expansion.

Tri-Carb 5110TR

Precision LSC for the most demanding applications, designed with α-β Discrimination counting mode, ultra-low level counting mode and pulse amplitude comparison analysis mode.

Quantulus GCT 6220

A multi-user laboratory platform for environmental measurement and conventional counting measurement. Especially suitable for detecting ultra-low level α and β Environmental applications of radioactivity.

Application of carbon dating (fossil dating, geological dating, ancient tree dating, wine age)

primary productivity

Phosphorus cycle in the ocean and its regulation mechanism on global marine primary productivity

High sensitivity BGO probe

BGO (bismuth germanate) probe greatly improves the detection sensitivity
4 π type surround design to further improve sensitivity
Factory preassembled temperature control device to protect the counting stability of the probe
The lowest background value can reach 5-1 CPM, which is the world's highest sensitivity ultra-low background liquid scintillation spectrometer

Tr-lsc time resolution technology

Background noise such as ambient radiation is a multiphoton event, β Decay into a single photon event.
Time resolution technology can effectively distinguish cosmic rays, chemiluminescence events and actual samples β Flashing pulse

Patented GCT protection compensation technology - restore the truth β Decay event

α/β Screening technology - compared with the traditional method, the resolution of alpha beta screening is higher and the time required to calculate alpha / beta standard is reduced by 90% by using PSA histogram

Quantasmarttm software, with powerful multitasking function, has an unlimited number of assays in a secure multi-user environment and a simple network environment. Alpha beta

screening can effectively distinguish alpha and beta counts in mixed samples
The replay function reanalyzes the sample without repeated counting.
