Unlabelled:
A sensible and rapid spectrophotometric assay for adrenaline was developed.
Material And Method:
The method is based on the reaction with ammonium molybdate and sodium nitrite in acid medium.
Results:
The obtained compound is stable, soluble in water and has the absorbtion maximum at 405 nm. Beer's law is valid within a concentration range of 20-160 microg/mL. The validity of the method was tested by statistical analysis of the experimental data using the linearity, the scale's calibration factor, the detection limit, the quantification limit and the precision.
Conclusions:
A new method for the assay of adrenaline in pharmaceutical products has been developed.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
Enzyme-Linked Immunosorbent Assay
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or quantified.
