Title: Apparatus and method for reproducibly modifying localized absorption and scattering coefficients at a tissue measurement site during optical sampling
Inventor: ACOSTA GEORGE
IPC: A61B5/1495
Filed: 2001-07-09
Abstract: An apparatus for varying localized absorption and scattering coefficients at a tissue measurement site in a controlled and reproducible manner during optical sampling of a tissue volume by controlling the pressure applied to a tissue measurement site by a spectroscopic analyzer allows applied pressure to be maintained at a constant level, or the applied pressure may be varied in a controlled, reproducible manner as a function of time. A rest for receiving a body part holds the body part in a fixed position and at a fixed elevation. A  mechanical system advances a fiber optic probe until it makes contact with the body part with a constant amount of pressure. The applied force is supplied by a counterweight on a single arm balance. A temperature control allows the temperature of the fiber optic probe to be equilibrated with the temperature in the immediate vicinity of the tissue measurement site. Alternate embodiments allow the fiber optic probe to be brought into direct contact with the tissue measurement site, and displaced a known distance into the tissue.  The invention is also embodied as a method in which the absorption and scattering coefficients for successive spectral measurements are calculated to determine optimum depth of penetration for detection of a target analyte.

Patent CA-2419474-A1 (CA)
Title: Bioreactor and bioprocessing technique
Inventor: RAO GOVIND
IPC: G01N21/64
Filed: 2001-08-14
Abstract: The invention bioprocessing system and technique relies on non-invasive optical chemical sensing technology wherein an optical excitation source excites an optical chemical sensor. The optical chemical sensor then emits luminescence or absorbs light which is measured by a detector. The luminescence emitted from the chemical sensor or the amount of light absorbed by the chemical sensor is related to the concentration of an analyte, such as oxygen. If the luminescence emitted changes, or if the amount of light absorbed changes, then the concentration of the analyte has changed. Using such a system to measure and adjust multiple parameters at one time allows one to efficiently and cost-effectively determine optimal conditions for a given cell type and/or cell environment. By combining cell cultivation with optical chemical sensing technology, cultivation can be successfully and rapidly performed, controlled and monitored in small volumes in an automated, parallel fashion at less expense than current bioprocess techniques. Figure (1) is a schematic diagram of a high throughput microbioprocessing system in accordance with one embodiment of the present invention.

Title: Method and system for peak parking in liquid chromatography-mass spectrometer (lc-ms) analysis
Inventor: SWART REMCO
IPC: G01N30/86
Filed: 2001-10-03
Abstract: A reconfigurable multi-mode post-column analysis system improves resolution of liquid chromatography detection data by providing a parking or MS/MS detection mode in which flow of column eluent is substantially reduced to provide greater analysis time within a single eluting detection peak. A micro switching valve unit is reconfigurable between normal (MS) mode that passes column eluent directly to an MS unit, and a peak parking (or MS/MS) mode, in which normal mode column flow is interrupted, and the gradient halted, while more slowly flowing the detection peak of interested through the MS unit. A  micro syringe pump contributes to the substantially lower MS/MS flow rate. A  MS control unit controls micro switching valve valves to reconfigure between MS and MS/MS modes. After a detection peak, MS mode is reestablished, and the system primary pump returns to normal mode flow rate and gradient conditions.  Mode changes can be carried out for each chromatogram detection peak.
