Abstract:

The highly sensitive spectrophone assembly of the subject invention simultaneously and continuously provides an accurate measure of the absorption of electromagnetic radiation by atmospheric gases and particulate matter by providing successive flow through chambers. The gases and particulate matter pass through the first chamber, are directed through a filter where the particulate matter is removed, leaving the gases to flow through the second chamber. The signal representative of the absorption of energy is generated in each chamber and fed into a differential amplifier, to provide an accurate indication of the particulate matter in the atmosphere being monitored. Grounding one side yields a signal attributable to the gaseous absorption. Author
