Environmental Analyses Services

The following analytical techniques are used:

• Classic: gravimetric and volumetric techniques
• UV-Vis: molecular ultraviolet/visible absorption spectrometry
• GC-FID: gas chromatography flame ionization detector

Automated methodology: 

• Automated gas analysis (CO, NOx, SOx, O2)
• Physical gas parameters: temperature, pressure, velocity
• Noise level measurements (Decibel ABC): class 1 integrating sound level meter
