| 20110318774 | DUAL SAMPLE CARTRIDGE AND METHOD FOR CHARACTERIZING PARTICLES IN LIQUID - The present invention relates to an apparatus for characterizing particles suspended in a liquid, especially a self-contained disposable cartridge for single-use analysis, such as for single-use analysis of a small quantity of whole blood. Furthermore, the present invention relates to a method for characterizing particles in liquid and a device for sampling a small and accurate volume of liquid. The apparatus comprises a housing having a mixing chamber and a collection chamber separated by a wall containing an opening, a first bore in the outer surface of the housing for entrance of a liquid sample, a first cavity for receiving and holding a first liquid sample, and a second cavity for receiving and holding a second liquid sample. | 12-29-2011 |
| 20110027825 | HIGH RESOLUTION CLASSIFICATION - The present invention relates to a method of determining pulse height distribution by using an apparatus comprising: an analogue to digital pulses height categorisation unit comparing the pulse to analogue threshold voltages and counting each event within each pulse height category using a micro controller. The method may comprise the steps of i) selecting a first set of threshold voltages, ii) performing a first measurement using the first set of threshold voltages, iii) selecting a new set of threshold voltages different from the first set of threshold voltages, iv) performing a new measurement using the new set of threshold voltages, v) determining cell size distribution based on the first measurement and the new measurement. The present invention further relates to an apparatus comprising an analogue to digital pulses height categorisation unit comparing the pulse to analogue threshold voltages, a micro controller configured for counting each event within each pulse height category, the micro controller further configured for i) selecting a first set of threshold voltages, ii) performing a first measurement using the first set of threshold voltages, iii) selecting a new set of threshold voltages different from the first set of threshold voltages, iv) performing a new measurement using the new set of threshold voltages, v) determining cell size distribution based on the first measurement and the new measurement. | 02-03-2011 |
| 20080314130 | Detection and Subsequent Removal of an Aperture Blockage - The present invention relates to a particle characterisation apparatus in which particles suspended in a liquid are passed through an aperture, in principle one by one, to enable characterisation of the particles, for instance by Coulter counting. In particular the present invention relates to an apparatus for characterizing particles suspended in a liquid sample, comprising a housing with a mixing chamber | 12-25-2008 |
