Detailed explanation-1: -A blank solution is a solution containing little to no analyte of interest, usually used to calibrate instruments such as a colorimeter.

Detailed explanation-2: -A blank is a sample that contains everything except for the analyte of interest. For example, if you are doing a UV-vis experiment to measure concentrations of Green Fluorescent Protein, the protein has to be dissolved in a solvent. The blank is a sample of just the solvent.

Detailed explanation-3: -A method blank (MB) is an analyte-free matrix such as DI Water for liquids or cleaned sand for solids and/or soils that is processed in exactly the same manner as the samples. The main function of the MB is to document contamination resulting from the analytical process.

Detailed explanation-4: -A reagent blank is a mixture of any solvent(s) and/or reagent(s) that would be presented to the detector for analysis of a test sample and is analysed to determine if it contributes to the measurement signal.
