Techniques used for analyses:
- Dissolved oxygen Winkler's volumetric method
- Electrochemistry:
- pH determination with and without autosampler
- electrical conductivity determination
- total alkalinity and strong acidity determination wit autosampler (Gran's method)
- UV-VIS spectrophotometry range 190-1100 nm
- Spectrophotometry with autoanalyser colorimetric discrete and segmented flow autoanalyser
- ICP-OES spectrophotometry atomic emission with concentric and ultrasonic nebulizer and sample preparation with microwave mineralizer
- Ion cromatography five instrumental lines for the determination of anions and cations
- Catalytic combustion for TOC & TN analyser with infrared (IR) and chemiluminescence (CLD) detectors
- Autoclave for the mineralization of water samples .
The figures show the analytes with the techniques used, analytical intervals, quality controls performed and the number of samples analysed in recent years in the water chemistry laboratory of the CNR of Verbania.
