US Patent:

20090257047, Oct 15, 2009

Filed:

Apr 13, 2009

Appl. No.:

12/422817

Inventors:

Frank S. Higgins - Naugatuck CT, US
John A. Seelenbinder - Watertown CT, US

Assignee:

A2 TECHNOLOGIES, LLC - Danbury CT

International Classification:

G01N 21/00

US Classification:

356 51, 356436

Abstract:

A method for determining an amount of polar substance in a non-polar media includes adding a surfactant to increase a dispersion of the polar substance in the non-polar media and to increase the optical absorbance of the polar substance in the non-polar media to create a sample, passing an initial optical spectrum through the sample, measuring a resultant optical spectrum exiting the sample, relating the resultant optical spectrum to a predetermined quantitative calibration, and determining a concentration of the polar substance in the non-polar media based on the relation of the resultant optical spectrum to the quantitative calibration.

G01N 1/40

Abstract:

A device and method for preparing a sample for solid-liquid or liquid-liquid extraction are provided. In one embodiment, a device includes a sealed container including an opening for receiving a solid sample and a reservoir. The reservoir includes a solvent or is adapted to receive a solvent. The solid sample and the solvent are mixed in the reservoir and to concentrate at least one component of the sample into the solvent within the reservoir. The concentrate is settled into a solvent layer within the container. The solvent layer is sampled via a port. A method includes introducing a solid sample to a solvent; creating a solution by mixing the solid sample with the solvent; allowing the solvent solution to settle into at least one layer; and sampling within at least one layer.

International Classification:

G01N 33/18

US Classification:

Abstract:

Solvent extraction to quantify contamination of a sample by a hydrocarbon contaminant is performed by providing a defined quantity of the sample, providing a defined quantity of a siloxane solvent, mixing the defined quantity of the siloxane solvent and the defined quantity of the sample to extract the hydrocarbon contaminant from the sample to form a contaminant solution with the siloxane solvent, and separating the contaminant solution from the sample. A concentration of the hydrocarbon contaminant in the contaminant solution can be measured by vibrational spectroscopy. Siloxane solvents are CFC free, VOC exempt, odorless, colorless, low to moderately flammable, non-toxic, and safe for incidental skin contact. Some are even used in cosmetic products.
