Abstract
A point of use analyzer includes pump, valve, port, and storage channel. The storage channel may hold multiple assay packets composed of reagent aliquots separated by bounding slugs. The storage channel may define an elongated lumen having two ends with each of the ends coupled to the valve. A sampling device for use with the analyzer engages the port and may include a recurrent coaxial tube having a separation medium. A method of using the analyzer with the sampling device includes steps of pumping a fluid to displace a sample into the separation medium and out through the opposed connection.
