Title:
PARTICLE ANALYZER AND PARTICLE TEST CONTROL METHOD AND DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2013/064033
Kind Code:
A1
Abstract:
An ion analyzer and a test control method and device thereof. The method comprises: extracting a diluted sample, preserving a part of the sample, and detecting whether a pore blocking event occurs during a technical test process; when the pore blocking event occurs, controlling to suspend the test of the sample, and performing an unblocking operation; and after the unblocking operation is completed, controlling a liquid adding system to again extract the preserved part of the sample from a reaction cell or a passage of the liquid adding system and inject the extracted sample into a counting cell, and then starting to perform a counting test through an impedance method again on the sample in the counting cell. The method makes full use of the remaining diluted sample for a second test to eliminate the impact of pore blocking that occurs in the first measurement of the sample on the test result, and the sample does not need to be again placed at a position under test for sample re-extraction and re-dilution, thereby reducing the probability of pore blocking. Also disclosed is a device using the method.
