Filed:

Jun 10, 2004

Appl. No.:

10/866009

Inventors:

David Anafi - Wellington FL, US
Glen Ramsay - Lakewood NJ, US
Jeff MacDonald - Little Egg Harbor NJ, US
Peter Halatin - Howell NJ, US
Charlie Schwartz - Toms River NJ, US

Assignee:

Wyatt Technology Corporation - Santa Barbara CA

International Classification:

G01N 21/55

US Classification:

356445

Abstract:

The invention relates to a surface plasmon resonance system method. The system has at least one light source operable to generate a source beam, a prism having a rear surface at least partially coated with a metallic coating and optionally a dielectric layer. At least one layer under test is positioned on the rear surface of the prism. The source beam is directed at the layer under test thereby defining an angle between the source beam and the rear surface of the prism. A detector is operable to detect light that is reflected or scattered by the layer under test. The source beam is directed towards the layer under test at a selected angle. The source beam is also shifted in at least one plane to illuminate a specific portion of the layer under test based on the selected relative angle and the position of the layer under test on the rear surface of the prism. The rear surface of the prism can be illuminated in one-dimensional or two-dimensional array like fashion.

US Classification:

356445, 356244

Abstract:

A spectroscopy system has at least one light source operable to generate a source beam and a prism having a rear surface. A support block is disposed on the rear surface of the prism. The support block is formed with at least one sample well having a center and defines a substantially vertical rear cell surface having a center. The source beam is aimed at the sample well. A syringe filled with a membrane solution and having a needle with a distal end disposed in front of the sample well. The distal end is aimed at a point above the center of the rear cell surface. The syringe is operable to eject a stead stream of membrane solution from the needle onto the circular rear cell surface thereby forming a membrane defining at least a portion of a layer under test. The membrane has a substantially uniform thickness that covers substantially the entire rear cell surface. The system also includes a detector operable to detect light that is at least one of reflected and scattered by the layer under test.

Assignee:

AVIV BIOMEDICAL, INC. - Lakewood NJ

International Classification:

G01N 21/64
G01N 33/72

Abstract:

A hematofluorometer an excitation source configured to generate an excitation beam, a fluorescence detector configured to a fluorescence beam, and a housing configured to receive a reagent kit for detecting bilirubin in a fluid sample. The reagent kit includes a body defining at least one fluid receiving well and an optical window positioned over each at least one fluid receiving well and a light passage window opposite each optical window. Each window is formed of a material having a fluorescence intensity that is of a lower magnitude than the fluorescence to be detected from the bilirubin. A light sensor within the housing is configured to detect light passing through the reagent kit.
