Until now, the carbonates analysis was made by hand, spending a lot of time to prepare the sample and the analysis, only to obtain, after all that process, results with a high uncertainty level. The CO-202 is a new semi-automatic unit able to undertake the analysis of Carbonates in less than three minutes, eliminating the uncertainties, improving the repeatability and increasing the easiness and comfort when making the analysis according to the norm.



Based in the principle of decomposition by acid attack, the CO-202 transforms the carbonates and bicarbonates of the CO2 sample, quantifying them afterwards in an infrared cell.

Double measure range controlled by the computer and the massflow controller, making it possible to analyze samples with very low contents (slurrys) to limestone samples.

You can undertake both solid and liquid samples without preparing them previously.
