Humidity-controlled chamber for a thermogravimetric instrument

Image Number 7 for United States Patent #7048435.

Embodiments of the present invention relate to apparatus, systems and methods for adding a humidity-controlled system to a thermogravimetric instrument. A humidity-controlled chamber incorporates a housing, a humidifier, a sample chamber, a reference chamber, Peltier devices, humidity and temperature sensors, and gas transmission lines into a single unit. This single unit along with an electronic control unit and mass flow controllers provide a humidity-controlled system designed to control the atmosphere of TGA sample and reference chambers simultaneously. A system comprising an arm, motorized linear actuator and electronic control unit, allows a humidity-controlled chamber to be automatically opened and closed, in turn, allowing reference and sample chambers to automatically be accessed.
