    摘要: A system is presented for evaluating the performance of a particle detecting and measuring instrument wherein the instrument receives a specimen and detects the number of particles on the specimen and measures the descriptive parameters of the particles. The system includes a known specimen received by the instrument and wherein the known specimen has known particles on the specimen, with known parameters of each known particle on the specimen. The instrument detects the known particles and measures the parameters thereof. A matching of individual measured particles is made against individual known particles by means of selected known parameters thereof. A comparison is made of the parameters of each measured particle against the parameters of each known particle to which the measured particle was matched and an indication is provided of the instrument's performance as a function of the matching and the comparison.

    摘要: 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.

    摘要: The flow cytometry system of the present invention includes a flow channel including an interrogation zone. A light source and a light detector are connected to the interrogation zone, such that a sample flowing through the interrogation zone can be optically analyzed through methods known in the art of flow cytometry. A bubble detector is connected to the flow channel. A controller is connected to the bubble detector and is adapted to perform a predetermined output in response to the detection of a bubble in the flow channel. The predetermined output may include alerting a user as to the presence of a bubble, flagging potentially corrupted data, and ceasing data collection until the interrogation zone is clear of bubbles.

    摘要: In an evaluation method for a particle counter, a detector generates a signal in response to the presence of particles in a measuring area in which a liquid flow is conveyed. The sensor signal is treated by a signal processing device and is converted into a display value, taking into account at least one calibration factor. The sensor signal is treated in such a way that the individual residence times of the particles in the measuring zone are determined within a given lapse of time and a summated signal is formed by summating the residence times. The signal is used to represent the display value, taking into account the at least one calibration factor. A device for carrying out this includes a signal processing unit with a comparator circuit, a clock-pulse generator and a summation device in the form of a pulse counter, for example, in order to form the summated signal.

    摘要: The invention describes novel methods for calibrating or standardizing flow cytometry instruments using synthetic polymer particles or beads having physical properties which provide advantages for their use in such instruments. The polymer particles or beads employed in the calibration methods are spherical, have an average particle diameter of from about 1 to about 8 microns, a relatively narrow particle distribution, and a low refractive index, i.e., from about 1.35 to about 1.45. The particles are safe, stable for long time periods and are particularly suitable for employment as hematology analyzer calibration substances. The invention provides an advantageous improvement over the types of standards currently used to calibrate a variety of instruments that rely on light scatter combined with other parameters to identify and measure biological particles or cells, as well as nonbiological particles. In particular, using the calibration/standardization method and polymer particles according to the present invention allows hematology instruments to be calibrated and standardized for subsequent accurate and reliable determinations of red blood cells, reticulocytes, white blood cells and platelets in whole blood samples.
