Problems solved by technology

When such an instrument has a considerable number of tubes or conduits, considerable time and skill is required to repair such tubes / pipes and their associated fittings
In addition, such service also entails incorrect connections (where the tubes are connected to the wrong ports), poor connections where the mounting and / or tubes may be damaged or subjected to undue stress that may lead to premature failure, or no connections ( tube is simply not connected to its required port)
This situation can lead to leaks and / or other undesired results
In addition, such incorrect connections or leaks pose a safety hazard in situations where hazardous or flammable gases are used

Embodiment Construction

[0008] figure 1 is a schematic perspective view of a process analytical instrument according to an embodiment of the present invention. Gas chromatograph (analyzer) 10 includes an analysis module 12 that includes most of the chromatographic analysis mechanism for chromatograph 10 . Such as figure 1 As shown, the chromatograph 10 has a plurality of tubes or conduits 16 that must be connected between the modules 12 and the analyzer housing 24 . According to an embodiment of the present invention, the plurality of tubes or conduits 16 are terminated (on at least one end) with a modular removable tube rack 18 which facilitates quick and safe Replace the chromatographic analysis module 12. Embodiments of the present invention connect multiple tubes or conduits between the analyzer housing 24 and the module 12 in a manner that does not use separate fittings. In addition, the utilization of modular tube racks 18 allows for reliable sealing of multiple tubes or conduits in dispens...

Abstract

A process analytic instrument includes an analytical module configured to analyze a process fluid and a removable tube carrier coupled to the analytical module. The analytical module has a plurality of inlet ports in a sealing surface. The removable tube carrier has an end with a plurality of apertures aligned with the plurality of inlet ports of sealing surface of the analytical module. The removable tube carrier fluidically couples a plurality of tubes to the analytical module when the end of the removable tube carrier is biased into the sealing surface of the analytical module.

Description

Background technique [0001] Process analytical sensors and instruments are employed in a variety of industries to measure and control gases and liquids within processes. Process analyzers include, but are not limited to, process gas chromatographs, process gas analyzers, process hydrocarbon analyzers, continuous emission monitoring systems (CEMS), and the like. [0002] Process analytical instruments, such as gas chromatographs and complex gas and / or liquid analyzers or meters, often require one or more connections to various gases, fluids, air or vent lines. Installation or maintenance of such equipment requires that these connections be made separable using stainless steel, polymer or other suitable commercially available industry standard fittings. When such an instrument has a substantial number of tubes or conduits, servicing such tubes / pipes and their associated fittings requires considerable time and skill. In addition, such service also entails incorrect connections ...
