New developed data treatments for the characteristic linear array ayah 5SX1-T-1D-CFI analyzer segment response profile and generalization

Abstract EN

Derivative spectrophotometry is one of the analytical chemistry techniques used in the analysis and determination of chemicals and pharmaceuticals.

This method is characterized by simplicity, sensitivity and speed.

Derivative of Spectra conducted in several ways, including optical, electronic and mathematical.

This operation usually be done within spectrophotometer.

The paper is based on form of a new program.

The program construction is written in Visual Basic language within Microsoft Excel.

The program is able to transform the first, second, third and fourth derivatives of data and the return of these derivatives to zero order (normal plot).

The program was applied on experimental (trial) and reals values of sulphate determination in the form of barium sulphate by a Linear Array Ayah 5SX1-T-1DCFI Analyser.

The data was collected through an Array M3500A 6.5Digit Digital Multimeter linked between the spectrometer and computer.
