Abstract
Systems and methods are described, and one method includes passing an optical beam through a volume of the gas to a reception surface, applying spectroanalysis to the optical beam received at the reception surface, and determining from the spectroanalysis whether a liquid is carried by the volume of the gas.
Claims20
A method for determining whether a liquid is carried by a gas, the method comprising:
- passing an optical beam, from an optical source, through a volume of the gas, to a reception surface;
- applying a spectroanalysis to the optical beam as received at the reception surface, and outputting a corresponding spectroanalysis signal;
- and
- determining, based on the output spectroanalysis signal, whether a liquid is carried by the volume of the gas.

An apparatus for determining whether a liquid is carried by a gas, the apparatus comprising:
- a measurement housing, configured to enclose a chamber, and to include a gas inlet port into the chamber and a gas outlet port from the chamber;
- an optical element, having a surface facing the chamber;
- an optical source, configured to pass an optical beam into the optical element in a direction to be incident on the surface facing the chamber;
- a spectroanalysis unit, configured to receive the optical beam subsequent to incidence on the surface facing the chamber, and output a corresponding spectroanalysis signal;
- and
- a processing unit configured to receive the output spectroanalysis signal and based thereon to determine whether a liquid is carried by a volume of the gas received into the chamber through the gas inlet port.

A method for determining whether a liquid is carried by a gas, the method comprising:
- transmitting an optical beam into an optical element, the optical element having a surface that faces a volume of the gas, wherein the optical beam enters the optical element at an entry location on the optical element, is incident on the surface that faces the volume of the gas, and exits the optical element as an exit beam from an exit location on the optical element;
- applying a spectroanalysis to the exit beam;
- and
- determining, based on a result the spectroanalysis, whether the liquid is carried by the volume of the gas.
