Soluzione standard

Descrizzione di u produttu

Standard solution is a solution with a known accurate concentration and is often used to calibrate instruments, validate analytical methods, establish a standard curve for quantitative analysis, ecc.

Features

Accurately known concentrations.

It is widely used in many chemical analysis methods such as titration analysis and spectrophotometry.

Scopu

Titrant in titration analysis: Used to chemically react with the substance under test and calculate the content of the substance under test by measuring the volume of the standard solution consumed.

Drawing a working curve or as a calculation standard: In analytical methods such as spectrophotometry, the relationship between absorbance and concentration is drawn using standard solutions of different concentrations to determine the concentration of unknown solutions.

Calibrate instruments and determine experimental conditions: used to calibrate experimental instruments such as conductometers and pH meters to ensure the accuracy of measurement results.
