US Patent:

20090241698, Oct 1, 2009

Filed:

Mar 24, 2009

Appl. No.:

12/410246

Inventors:

Michael J. Biksacky - Madison WI, US

International Classification:

G01N 1/14

US Classification:

7386383

Abstract:

A segmented sampling apparatus is designed to extract a sample from a source and deliver the sample to a collector for storage or analysis. The sample is extracted from the source at a sample withdrawal or extraction rate but is delivered to the collector at a faster rate. Air is injected into or drawn into the apparatus which allows for an expedited sample delivery rate.

International Classification:

C12M 1/34
G01F 1/708
G01F 15/00
G01P 5/18
G01F 25/00
C12M 1/00

Abstract:

An apparatus and method for determining fluid flow (e.g., sterile media flow, filtrate flow, etc.) through tubing is provided. The apparatus includes an air source, a flow valve, a first sensor, a second sensor, and a media tubing section extending between the first sensor and the second sensor. In operation, air from the air source is introduced by the flow valve into a fluid flow to create a lead line of fluid immediately following the introduced air. As the lead line of fluid passes each sensor, the sensors are used to determine a time between when the lead line passes the first sensor and the second sensor and that determined elapsed time is used, along with a determined volume of the media tubing section to determine the rate of flow of the fluid flow.
