Particle analyzer for analyzing particles

摘要

A particle analyzer may include a sampling unit configured to collect samples containing particles; a sample preparing unit configured to prepare different sub-samples; a reaction unit configured to incubate the sub-samples and one or more corresponding reagents respectively and provide them to the injecting unit; an injecting unit configured to inject the sub-samples to the optical unit; an optical unit configured to irradiate the sub-samples to obtain particle information; a processing unit configured to process and output the particle information; and a threshold value unit configured to compare a total number of particles with a pre-determined threshold value and to output a result of the comparison to the injecting unit to control subsequent injection of one or more sub-samples.

1. A particle analyzer comprising:
a sampling unit; a sample preparing unit; an optical unit configured; an injecting unit; a reaction unit; a processing unit; and a computer readable medium with encoded computer-executable instructions that, when executed by the processing unit, cause the processing unit to perform operations for outputting the particle information for an injection cycle, the operations comprising:
instructing the sampling unit to collect samples containing particles;instructing the sample preparing unit to prepare a plurality of sub-samples;instructing the reaction unit to incubate the particles and one or more corresponding reagents;instructing the injecting unit to inject a first sub-sample having a first preset volume and a first number of particles to the optical unit;instructing the optical unit to irradiate the injected particles to obtain particle information associated with the particles;comparing the first number of particles with a pre-determined threshold value;outputting a result of the comparison to the injecting unit; andcontrolling a volume of a subsequent, second injection of at least a second sub-sample based on the result of the comparison, wherein the volume of the second injection is different than a second preset volume of the second sub-sample.
