Abstract

A gas analyzer system for analyzing and monitoring samples of compressed or ambient gas such as breathing air and informing the user as to the results of the sample'"'"'s gas purity without the gas sample having to be physically transported to an accredited laboratory. The system comprises a gas analysis module situated at a user facility for receiving the contents of a gas sample and detecting gas impurity characteristics, and a server situated at a remote certification and monitoring center and electrically coupled to the gas analysis module via a bi-directional communications link such a computer network connection. The remote server receives and stores the gas purity characteristics in the form of gas impurity data obtained from the analysis module. The module includes a calibration canister containing a known gas. The module executes onboard calibration by analyzing the calibration gas and comparing it to known data stored on the module.

Claims

1. A method for calibrating a compressed breathing air analysis module, comprising the steps of:

providing said compressed breathing air analysis module at a user facility with a compressed breathing air sample from a calibration canister contained on-board on said compressed breathing air analysis module;

detecting, on said compressed breathing air analysis module, one or more compressed breathing air characteristics of said compressed breathing air sample;

comparing, on said compressed breathing air analysis module, said one or more compressed breathing air characteristics of said compressed breathing air sample to known calibration data stored on said module, said known calibration data corresponding to the actual characteristics of said compressed breathing air sample; and

in response to determining that said detected compressed breathing air characteristics are dissimilar to said actual characteristics of said compressed breathing air sample stored on said module, adjusting said compressed breathing air module to account for dissimilarities.

2. The method of claim 1, wherein results of said step of comparing are transmitted by said compressed breathing air analysis module to a server maintained by a remote compressed breathing air certification and monitoring center over a bi-directional communications link.

3. The method of claim 1, wherein results of said step of comparing are displayed on a display of said analysis module.

4. The method of claim 1, wherein results of said step of comparing are displayed on one or more status lights of said analysis module.

5. The method of claim 1, further including the step of receiving, on said analysis module from a server over said bi-directional communications link, one or more calibration instructions used for said step of adjusting said compressed breathing air module to account for dissimilarities.

6. The method of claim 1, wherein said compressed breathing air analysis module comprises:

an inlet receiving said compressed breathing air sample;

a compressed breathing air compartment in flow communication with said inlet;

a plurality of compressed breathing air sensors in fluid communication with said compartment, said sensors capable of detecting said compressed breathing air impurity characteristics of said compressed breathing air sample and generating compressed breathing air impurity signals corresponding to said compressed breathing air impurity characteristics;

a chipset;

a communication device in electrical communication with said chipset;

a canister containing a calibration compressed breathing air comprising at least a portion of said compressed breathing air sample, said calibration compressed breathing air having known physical characteristics, said canister in flow communication with said compressed breathing air compartment;

wherein said compressed breathing air sensors are electrically coupled to said chipset, said chipset receiving said compressed breathing air impurity signals and converting said compressed breathing air impurity signals into said computer-readable compressed breathing air impurity data;

wherein said communication device receives said computer-readable compressed breathing air impurity data from said chipset and transmits said data to said server over said bi-directional communications link.

7. The method of claim 6, wherein said communication device is wireless.

8. The method of claim 6, wherein said canister is engaged with a solenoid, said solenoid electrically coupled and controlled by said chipset to introduce said calibration compressed breathing air into said compressed breathing air compartment to execute said step of comparing.
