Abstract

An instrument (10) for detecting leaks in a hermetically sealed package (100). The instrument (10) includes (i) a hollow needle (20), (ii) a mass flow rate sensor (70) in sealed fluid communication with the lumen defined by the hollow needle (20), and (iii) a vacuum pump (60). The vacuum pump (60) is in fluid communication with the lumen defined by the needle (20) for evacuating gas (102) from the hermetically sealed package (100), and in fluid communication with the mass flow rate sensor (70) for directing mass flow from the evacuated package (100) into operable contact with the mass flow rate sensor (70) so as to permit sensing of any continuing mass flow from the evacuated package (100). The instrument (10) may further include an oxygen sensor (40) in sealed fluid communication with the lumen defined by the hollow needle (20) for analyzing the oxygen concentration of the gas (102) within the hermetically sealed package (100).
