## Abstract

A gas analyzer includes a sample inlet, a sample outlet, a detector, a monitoring component, and a controller. The sample inlet is configured to receive a sample and is coupled to the sample outlet. The detector is operably disposed between the sample inlet and the sample outlet and is configured to provide an indication relative to the sample. The monitoring component is configured to provide a diagnostic indication regarding at least one component of the gas analyzer. The controller is configured to control flow through the gas analyzer and is operably coupled to the detector to analyze the sample, provide the analysis to the monitoring component, and provide the indication of health to an output.

## Claims

### Claim 1

A gas analyzer comprising:
a sample inlet, configured to receive a sample, coupled to a sample outlet;
a detector operably disposed between the sample inlet and the sample outlet and configured to provide an indication relative to the sample;
a microprocessor configured to provide a diagnostic indication regarding the detector of the gas analyzer and provide a fuzzy logic-based module to analyze behavior of gas analyzer parameters over time, and wherein the microprocessor is configured to control flow through the gas analyzer; the microprocessor being operably coupled to the detector to analyze the sample, provide an analytical output and provide the diagnostic indication; and
wherein the diagnostic indication is based on tracking historic data of parameters of the gas analyzer.

### Claim 2 (depends on 1)

The gas analyzer of claim 1, and further comprising at least one gas measurement stage disposed between the sample inlet and the sample outlet.

### Claim 3 (depends on 1)

The gas analyzer of claim 1, wherein the diagnostic indication comprises an indication of anticipated fault for the detector of the gas analyzer.

### Claim 4 (depends on 1)

The gas analyzer of claim 1, wherein the diagnostic indication comprises an estimated remaining lifetime remaining for the detector of the gas analyzer.

### Claim 5 (depends on 1)

The gas analyzer of claim 1, wherein the diagnostic indication comprises a detected issue with the detector of the gas analyzer.

### Claim 6 (depends on 1)

The gas analyzer of claim 1, wherein the diagnostic indication comprises a suggested course of action for the detector of the gas analyzer.

### Claim 7 (depends on 1)

The gas analyzer of claim 1, wherein the microprocessor is configured to provide a statistics-based monitoring function regarding the detector of the gas analyzer.

### Claim 8 (depends on 1)

The gas analyzer of claim 1, wherein the diagnostic indication regarding the detector comprises indicating a detector filament is out of balance.

### Claim 9 (depends on 1)

The gas analyzer of claim 1, wherein the diagnostic indication regarding the detector comprises indicating the detector is defective.

### Claim 10 (depends on 1)

The gas analyzer of claim 1, wherein the diagnostic indication regarding the detector comprises indicating the detector is dirty.

### Claim 11 (depends on 1)

The gas analyzer of claim 1, wherein the diagnostic indication regarding the detector comprises indicating the detector is in a power off state.

### Claim 12 (depends on 1)

The gas analyzer of claim 1, wherein the diagnostic indication regarding the detector comprises indicating the detector has degraded.
