A microanalytic 4πβ counter with anticoincidence shield for 3H 2 in 3He is introduced. As a low background microanalysis device of gaseous tritium
this instrument has advantages such as simple structure
high accuracy and low detection limit [N ( 3H 2) /N( 3He)<10 -11 ]. In this paper the structure and main performance of the counter is described and the test results for 3H 2 in 3He are given.
