(1)

Selectivity:

Selectivity factors are between 0 and 1; interferences may be

negative if the observed signal is reduced.

(2)

Detection Limits:

It is the minimum amount of

analyte (or concentration) that can be detected at a known level of

reliability.

(3)

Applicable Concentration Range:

Calibration curves are required. In addition, when the analysis is

made, the absorbance of at least one standard is measured again to determine errors that are caused by uncontrolled variables.

(4)

Thus, the deviation of the standard from the original calibration curve is used to correct the results

obtained for the sample.

(5)

Dynamic Range:

The use of the linear portion of the curve is preferred; the analytical

signal in this section is directly proportional to the amount of analyte.

(6)

There is no increase in the

response value at the analyte

concentrations above the dynamic range.

(7)

Limit of Detection (LOD):

It is the lowest content that can be measured with reasonable

determination.

(8)

Typically three times of the S / N (signal / noise); It is based on the standard deviation of noise.
