ABSTRACT:
An in-stream sample collection and conditioning system which is easier to implement and maintain, more cost effective, and more reliable than existing systems. The preferred embodiment of the present system contemplates a modular system adaptable to a variety of diverse configurations and criteria, the system having incorporated therein a base piece formed of interconnecting modular base members, the base piece having fluid passageways formed therein to provide fluid flow between the adjacent base member. Situated adjacent to each of the modular base members forming the base piece are modular conditioning components, each selected from a field of diverse conditioning types and configurations, and adapted for the contemplated use. The present invention further contemplates a unique and useful system for joining the various modular components forming the present system, in a manner which provides redundant leak resistance, flexibility in forming various conditioning requirements and adaptability to diverse existing sampling stream interfaces, as well as a new and unique method for attachment of the transport tube to the device body. Lastly, the preferred embodiment of the present invention contemplates a highly precise, low tolerance juxtaposition of the various components forming the present system, utilizing an extremely thin sheet, formed membrane/gasket member, implemented in such a manner as to provide high thermocycling characteristics as well as high pressure tolerance, coupled with a low failure/leakage rate.
