Abstract:
PROBLEM TO BE SOLVED: To provide a method for controlling one or more parameters of a flow cytometer type measurement system. SOLUTION: This method includes the step of monitoring the parameters of the measurement system during the measurement of a sample microsphere and the step of altering the parameters on the basis of monitoring in real time. A method separate from this method includes the step of monitoring the temperature in the vicinity of the measurement system, the step of altering the bias voltage of an avalanche photodiode in response to temperature using experientially led-out data, and the step of altering the output signal of a photomultiplier in response to the temperature using a characteristic curve. Some methods include the step of monitoring the temperature of a fluid wherein the sample microsphere is arranged. The fluid passes through the flow cytometer type measurement system to flow. This method also includes the step of determining the speed of the sample microsphere in the measurement system from the viscosity of the fluid at that temperature. COPYRIGHT: (C)2010,JPO&INPIT

Abstract:
Various methods for controlling one or more parameters of a flow cytometer type measurement system are provided. One embodiment includes monitoring parameter(s) of the measurement system during measurements of sample microspheres. The method also includes altering the parameter(s) in real time based on the monitoring. Another method includes monitoring a temperature proximate to the measurement system. One such method includes altering a bias voltage of an avalanche photo diode in response to the temperature using empirically derived data. A different such method includes altering output signals of a photomultiplier tube in response to the temperature using a characteristic curve. Some methods include monitoring a temperature of a fluid, in which sample microspheres are disposed, that will flow through the flow cytometer type measurement system. This method also includes determining a velocity of the sample microspheres in the measurement system from a viscosity of the fluid at the temperature.
Abstract:
A system and method for processing sample data from a flow analyser (420) employing hardware, such as a Field Programmable Gate Array (FPGA), to process the sample data in small pipelined steps. The processing includes a circular buffer where the read and write of data is synchronous, preventing buffer overrun or data loss. This pipeline processing approach allows increasing data acquisition channels or additional processing steps without limiting processing speed.

PROBLEM TO BE SOLVED: To provide a method for controlling parameters of a flow cytometer type measurement system.SOLUTION: In order to control parameters during measurement of a sample microsphere, a temperature proximate to a measurement system is monitored. In order to fix the length of time when the microsphere is present in a detection window, a movement velocity of the microsphere is determined by controlling a pressure applied to a sample in accordance with viscosity. A bias voltage of an avalanche photo diode used in a detector is altered in response to the temperature.
