520    For future studies of oceanic circulation it is necessary 
       to develop the tritium measurement via 3He ingrowth into a
       routine procedure with a high capacity for efficient use. 
       This paper attempts to demonstrate that this can be 
       achieved using a commercial helium isotope mass 
       spectrometer and special procedures for sample preparation,
       storage for 3He ingrowth, and 3He transfer from the 
       ingrowth containers into the mass spectrometer. This 
       method allows for measurement with a much higher precision
       and lower detection limit than is possible with counting 
       techniques. Additionally, the parameters and blanks in 
       routine operation of the system are discussed.
