Analytical system DUMATHERM® with pneumatic auto sampler and PC controller

Due to their manufacture, starch products only contain very low concentrations of proteins. Therefore, satisfactory analysis has only been possible to date using high sample weights and long analysis times. With its innovative detection method and fast and complete combustion, DUMATHERM® from C. Gerhardt, with its innovative detection method and fast and complete combustion for the detection of Nitrogen by Dumas, provides an interesting alternative to the currently still common Kjeldahl method.
