US Patent:

7617719, Nov 17, 2009
Filed:

Nov 30, 2006
Appl. No.:

11/606695
Inventors:

Chanmin Su - Ventura CA, US
Craig Prater - Goleta CA, US
Gregory F. Meyers - Midland MI, US
Bryant R. LaFreniere - Midland MI, US
Assignee:

The Dow Chemical Company - Midland MI
Veeco Instruments Inc. - Plainview NY
International Classification:

G01B 5/28
US Classification:

73105
Abstract:

A method and apparatus for its practice are provided of differentiating at least one component of a heterogeneous sample from other component(s) using harmonic resonance imaging and of obtaining information regarding the sample from the differentiation. In a preferred embodiment, an image is created of a property of a harmonic or a combination of a harmonics producing a response having a contrast factor between the sample's constituent components. The desired harmonic(s) can be identified either in a preliminary data acquisition procedure on the sample or, if the sample's constituent components are known in advance, predetermined. The desired harnonic(s) may be identified directly by the user or automatically through, e. g. , pattern recognition. A compositional map may then be generated and displayed and/or additional information about the sample may be obtained.

US Patent:

50883356, Feb 18, 1992
Filed:

Feb 26, 1990
Appl. No.:

7/485045
Inventors:

Bryant R. LaFreniere - Midland MI
Mark T. Zaranski - Freeland MI
Marvin P. Miller - Midland MI
Assignee:

The Dow Chemical Company - Midland MI
International Classification:

G01N 114
US Classification:

7386462
Abstract:

A plurality of liquid samples are introduced successively to and stored in a variable volume chamber formed in a sample container by periodically establishing communication between the chamber and a liquid source and increasing the volume of the chamber by the exact amount of the sample that is introduced into the chamber, and without varying the pressure of the liquid entering or accommodated in the chamber. The chamber remains at all times completely filled with liquid.
