Disclosed are methods and systems for analyte detection in a sample and more particularly, a biological sample. Methods and systems particularly relate to differentiating and/or identifying cell types in biological samples, such as blood samples, by adding antibodies specific to predetermined CD antigens. Other methods and systems relate to controlling the dynamic range of an assay for analyte detection.

A method for parallel determination of contrasting particles on a membrane when analyzing an accumulation of particles on the same membrane using an optical microscope is provided. The method involves increasing the transparency of the membrane to light radiation before analyzing particle accumulation.

A method includes receiving, from an imaging device associated with a robotic apparatus, an image signal including an object of interest represented in the image signal; receiving, by the robotic apparatus from an external agent, a task indication related to the object of interest, the task indication representative of a task to be performed by the robotic apparatus with respect to the object of interest; and responsive to receipt of the task indication: detecting salient features of the object of interest within the image; storing, by the robotic apparatus, a task context, the task context comprising data pertaining to the salient features and data pertaining to the task indication; and commencing, by the robotic apparatus, the task with respect to the object of interest.

An on-line measurement system for aerosol precursors emitted from industrial sources has three parts: online measurement part, pipeline cleaning part and automatic control part. The system includes: a particulate filter, high temperature intake pipe, two detergent tanks, an air pump, a cooling water pump, two detergent pumps, a condenser, an impinger, a cooling water meter, a salinity meter, a liquid flow meter, a gas flow meter, nitrogen cylinders, connecting pipes, control valves, computer control program etc. The aerosol precursor concentration Cg emitted from industrial sources is measured in the online measurement section. After every measurement, the pipeline is cleaned by the pipeline cleaning part to remove organic and inorganic residual. The automatic control part is controlled by the computer through a controlling program to control the working process of the system. The system has small area occupation, low investment cost, simple maintenance, convenient transformation and high applicability.

A rack for a diagnostic robot with at least one support for at least one container; at least one gas-outlet to supply the at least one container with a gas at a predefined but individually adjustable pressure level; a first gas pump to generate a gas at a predefined super-atmospheric pressure level; a second gas pump to generate a gas at a pre-defined sub-atmospheric pressure level; a first tubing system attached to the first gas pump and holding the gas generated by the first gas pump; a second tubing system attached to the second gas pump and holding the gas generated by the second gas pump; and at least one tube bridge, wherein one end of the bridge connects via a first valve into the first tubing system and the other end of the bridge connects via a second valve into the second tubing system, and wherein the at least one gas-outlet is connected to the center of the bridge.

The present invention relates to a multisystem for simultaneously performing a biochemical examination and a blood test or an immunity test, the multisystem including a multi-disc in which a biochemical examination unit, a blood testing unit and an immunity test unit are divided and formed in a fan shape based on a rotation center. There is an effect that it is possible to perform all of a biochemical examination for measuring concentration values of biochemical components of serum to diagnose vital functions, a blood testing for separating blood samples to measure and test the number and deformation of red blood cells or white blood cells, and an immunity test for measuring an antigen-antibody reaction of serum to diagnose and test cancer or viruses in one device at the same time by using the multi-disc according to the present invention.

An analyzer having an inner chassis surrounded by a housing includes sample and dilution probes, a mixing housing including first and second mixing chambers, a flow cytometer including a flow cell, and sample and sheath pumps configured to perform first and second pluralities of tasks, respectively. The first plurality of tasks includes: aspirating sample into the sample probe, dispensing sample from the sample probe into the first and second mixing chambers, delivering first sample-dilution fluid mixture to the flow cell, and delivering second sample-dilution fluid mixture to the flow cell. The second plurality of tasks includes: dispensing sheath to the flow cell in cooperation with the delivery of the first sample-dilution fluid mixture to the flow cell, and dispensing sheath to the flow cell in cooperation with the delivery of the second sample-dilution fluid mixture to the flow cell.

A filtering device is provided to an analyzing instrument to block the passage of oversized particles that may otherwise clog the aperture of a sample analyzing device. The filtering device can be arranged to be proximate to the mixing chamber. In certain examples, the filtering device is placed at or adjacent an output port of the mixing chamber.
