SAMPLE CLEANING ELEMENT FOR GAS ANALYZER
First Claim
1. A sample gas analyzer, comprising:
- a sample cell configured to receive a gas sample;
a sample tube having a body defining a passageway that is in communication with the sample cell, and the body including an intake portion; and
a cleaning element disposed upstream of the sample cell, the cleaning element comprising;
a body having a chamber configured to aid in imparting a rotational motion to a fluid stream entering the chamber;
an inlet port in communication with the chamber and configured and arranged for communication with the atmosphere; and
an outlet port in communication with the chamber and the sample cell.

Abstract
In one example, a sample gas analyzer includes a sample cell configured to receive a gas sample, a sample tube including a passageway that is in communication with the sample cell, and an intake portion. A cleaning element is disposed between, and arranged for fluid communication with, the sample tube and the sample cell, and includes a body having a chamber configured to aid in imparting a rotational motion to a fluid stream entering the chamber. The cleaning element also includes an inlet port that is in communication with the chamber and that is configured and arranged for communication with the atmosphere. Finally, the cleaning element includes an outlet port in communication with the chamber and the sample cell.

20. A method for sampling and evaluating a gas, the method comprising:
-
establishing a flow of a sample stream of gas, wherein the sample stream of gas includes solid matter; removing at least some solid matter from the sample stream of gas, so as to produce a clean stream of gas, by imparting a rotational motion to the sample stream of gas; and identifying one or more aspects of a constituent of the clean stream of gas by subjecting a sample of the clean stream of gas to an optically-based analysis. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
