Test card strip

Test strips utilize capillary action to move liquid samples along the paper, triggering a colorimetric reaction with chemical reagents in fixed zones. The resulting color change corresponds to the concentration of specific substances. They are used for rapid semi-quantitative detection in fields such as water quality and food safety.
Selection
Determine the test strip type based on the type of analyte; match the concentration range to be measured with the test strip's measurement range; consider the interference of the sample matrix on color development; verify the shelf life and storage conditions of the test strips; perform comparative testing with reference to standard methods.
