QC Examples

As explained in the Quality Control link in More Information the first step in the QC process is to scan the blocks of test strips using a densitometer.

After the block of strips are scanned they are loaded in an application that determines optical density of the individual spots on the block. This data is transferred to an Excel Workbook and treated with regression analysis using log transformation techniques to determine individual concentrations for each Spot Test Strip.

There are examples taken from an investigation of chromatography paper showing groups of ten 4 point external curves on the Quality Control Example page in the Spottest.co home page.
