Ammonia determination in wastewater
In this application note, an easy and reliable method for the determination of ammonia in wastewater is introduced. Ammonia was determined by steam distillation followed by colorimetric titration in boric acid with the MultiKjel and Metrohm Eco Titrator, respectively, providing reliable and reproducible results

Freeze drying of beads containing yeasts
The cell viabilities of microorganisms during storage are of economic importance for probiotic dietary food and feed supplements. By combining granulation and freeze drying, dust free particles homogeneous in size and composition can be obtained. This will enable a good particle flowability, an easier dosage and a faster reconstitution of the product can be obtained. Encapsulator as a granulator to prill the yeasts suspension into liquid nitrogen and form monodispersed beads that will then be freeze dried.
