1. The VCM content determination by turbidimetry on abnormal conditions (such as examination reparation in power cut and etc.

2. The analytical methods used display an established preference for the traditional methods of chromatography, spectrophotometry, potentiomentry, flame photometry, conductivity measurement, gravimetry, titration analysis, atomic absorption, turbidimetry and radiometry
