Embodiment Construction

[0023] The presently disclosed subject matter provides methods, systems, techniques, devices, and articles of manufacture for maintaining a stable temperature for analyzers, such as tunable diode laser-based gas analyzers. A certain mass of phase change material (PCM) is incorporated into the design of the housing for the analyzer. The PCM mass provides a thermal buffer at the phase transition temperature due to the absorption of latent heat when the PCM transitions to a higher entropy state (ie gas or liquid) or the release of latent heat when the PCM transitions to a lower entropy state (ie liquid or solid). Since the phase transition occurs at a fixed phase transition temperature, a large latent buffer heat exchange with the surrounding environment is performed, thereby isolating the analyzer element within the enclosure from changes in the ambient temperature to which the enclosure is exposed. This will help ensure the accuracy and repeatability of the analyzer readings. ...

Abstract

Thermally controlled enclosures that can be used with gas analyzers are described. The enclosures incorporate one or more phase changing materials that buffer ambient and internal heat loads to reduce the power consumption demand of mechanical or electronic heating apparatus. Maintenance of gas analyzer equipment at a consistent temperature can be important to achieving stable and reproducible results. Related systems, apparatus, methods, and / or articles are also described.

Description

[0001] Cross reference to priority documents [0002] This application claims priority under section 119(e) of title 35 of the United States Code (35 U.S.C. § 119(e)) from co-pending US patent application Ser. No. 12 / 347,368 filed December 31, 2008. Priority is hereby claimed on the above filing date, and the entire disclosure of the above application is incorporated herein by reference. technical field [0003] The subject matter described herein relates to housings that may be used in analytical equipment, including but not limited to gas analyzers, such as gas analyzers based on tunable diode laser spectroscopy. Background technique [0004] Gas analyzers, such as those utilizing tunable diode laser spectroscopy, typically require a laser source mounted on a heat sink or thermoelectric cooler (TEC) to obtain and maintain the laser emission required for selected trace gas analysis frequency. A thermistor and an electronic feedback control loop are typically used to stabi...
