VINDTA 3S in the lab (VINDTA # 005) | 3S packed for a cruise |
The VINDTA (Versatile INstrument for the Determination of Titration Alkalinity) is a system for titration of a sample with acid and analysis of the titration curve to calculate alkalinity. From the first manual instruments in the early nineties of last century, the actual VINDTA 3S evolved. The system was developed to meet the requirements in precision (better 0.1%) for open ocean CO2 research. A full titration takes less than 20 minutes and requires about 250 ml sample volume (~ 150 ml minimum).
