ABSTRACT:
The optoacoustic detector cell of an infrared laser optoacoustic spectrometer is interfaced to a source of gas under analysis, such as the atmosphere, by means of a relatively large area membrane separator. Gas to be analyzed is passed through the membrane separator, compressed by a compressor and then fed at a pressure of between 10 and 1000 torr into the optoacoustic detector cell of the infrared spectrometer for analysis therein. A method of tracing is disclosed wherein deuterium is incorporated into a system to be traced. The deuterium diffuses out of the body in extremely minute quantities which are then inducted into the optoacoustic detector cell of an infrared laser optoacoustic spectrometer via a palladium membrane separator and reactor, whereby an extremely sensitive detection or tracing system is obtained. Also a method of petroleum exploration is disclosed wherein trace quantities of hydrocarbon gases escaping from underground petroleum deposits are detected as a function of position over the area to be explored.
