Abstract
In one aspect, the present disclosure is directed to a sample cell for a dew point meter, the sample cell comprising: a flow channel configured to receive a gas sample, the flow channel comprising: a non-mirror window surface, wherein the flow channel is configured to allow a first optical beam originating from an optical source to impinge on the non-mirror window surface and output a second optical beam from the non-mirror window surface towards an optical detector.
Claims20
A sample cell for a dew point meter, the sample cell comprising:
- a flow channel configured to receive a gas sample, the flow channel comprising:
- a non-mirror window surface,
- wherein the flow channel is configured to allow a first optical beam originating from an optical source to impinge on the non-mirror window surface and output a second optical beam from the non-mirror window surface towards an optical detector.
A method of measuring a dew point, the method comprising:
- (I) receiving a gas sample in a sample cell for a dew point meter, wherein the sample cell comprises:
- a flow channel configured to receive the gas sample, wherein the flow channel comprises:
- a non-mirror window surface,
- wherein the flow channel is configured to allow a first optical beam originating from an optical source to impinge on the non-mirror window surface and output a second optical beam from the non-mirror window surface towards an optical detector;
- (II) controlling a temperature of the non-mirror window surface and/or a portion of the gas sample to produce a liquid component on the non-mirror window surface and/or in the gas sample;
- and
- (III) measuring the dew point of the gas sample with the dew point meter.
