Abstract: The present invention is directed to systems and methods which utilize a cavity ringdown spectroscopy (CRDS) technique for measuring vapor transmission rate through a barrier film by first allowing the vapor to accumulate over a period of time after a steady state condition has been achieved. In this manner, in one embodiment, water permeation through a plastic film, even at very low permeability rates, can be accumulated over time. The accumulated water vapor is then measured and a calculation made as to permeation per unit of time. One main advantage of the accumulated method is that minimum vapor detection is limited only by the ability to produce a good seal around the edges of the plastic film in the sample cell.

Abstract: A portable, small-sized device is provided to accurately conduct a leakage test for a liquid volume meter such as a pipette. In operation, pipette P is connected to the device main body side via a tube. A command from a central processing unit causes a pump to perform a suctioning operation to depressurize the pipette P side to a predetermined pressure.

The central processing unit determines whether there is leakage from the pipette P, and displays a judgment result on a display unit. In particular, when a diaphragm pump is used as the pump, the pulsation of an air flow occurring in a suction operation is attenuated in a pressure vessel so as not to have harmful effects on either the inspection results or the pipette P side.
