Digestion parameters

In addition to the acid mixture and weight in order for a digestion to be successful, the digestion temperature and digestion time are decisive. These parameters are determined in advance, stored in the method and must be monitored. The vapour pressures of the reaction mixtures increase exponentially with the temperatures. Beside this, gaseous by-products are obtained, which also cause a pressure increase in the vessels. For safety reasons, the pressure must therefore also be monitored.
