  • Moisture and volatiles analyzer
    Patent number: 10527533
    Abstract: A volatile content analysis instrument is disclosed that includes a cavity and a microwave source positioned to produce and direct microwaves into the cavity at frequencies other than infrared frequencies. A balance is included with at least the balance pan (or platform) in the cavity. An infrared source is positioned to produce and direct infrared radiation into the cavity at frequencies other than the microwave frequencies produced by the microwave source. A lens is positioned between the infrared source and the balance pan for more efficiently directing infrared radiation to a sample on the balance pan. The lens has dimensions that preclude microwaves of the frequencies produced by the source and directed into the cavity from leaving the cavity.
    Type: Grant
