4 Specifications
4.1 General
Chemical and biochemical sensors are used in various applications, for example, in the detection of target moleculesisubstances. the detection of growth, decrease, differentiation and cohesion in cells, the detection of adsorption or absorption, the confirmation of the competition reaction. etc. Concepts and specifications br chemical and biochemical sensors are shown in detail in 4.2 to 4.5.

4.6 Technical documents
The following 1) and 2) should clearly be defined in the specifications in the contract to be concluded between the manufacturer and customers,
1) When a term other than a) to d) shown below is used
a) Limit of detection: the minimum amount or concentration detectable by sensor cells
b) Limit of quantitatlon: the minimum amount or concentration detectable by sensor modules.
c) Maximum limit of determination: the maximum analyte amount or concentration on which quantitative analysis can be performed, also called the maximum limit of quantitation
d) Sensitivity: the dependence of the output of sensor elements and cells upon the detected amount or concentration, i.e., the slope of a calibration curve.
