Detailed explanation-1: -The component of interest in the sample is called the analyte, and the remainder of the sample is the matrix. In an analysis we determine the identity, concentration, or properties of an ana-lyte. To make this determination we measure one or more of the analyte’s chemical or physical properties.

Detailed explanation-2: -An analyte is the specimen extracted for analysis from a portion or sample using a specific extraction protocol. The GDC Data Model relates analytes to aliquots or portions or samples but is not a required biospecimen entity.

Detailed explanation-3: -Answer: characteristic of interest of an elements is called a variable.

Detailed explanation-4: -Analyte: A substance of interest that needs detection. For instance, glucose is an ‘analyte’ in a biosensor designed to detect glucose.

Detailed explanation-5: -The matrix, or sample matrix, is the collection of all of the components in the sample containing an analyte. = kX where k is a proportionality constant. The process of determining k is called a calibration. determination and control of the concentration of glucose in blood.
