Abstract

The oscillating element in a microbalance is provided with a filter on its oscillating end for the entrapment of matter whose mass is to be determined by passing the medium containing such matter therethrough. The oscillating element itself is hollow and the medium passes first through the filter and then through the oscillating element.
