The easiest solution to detect which version of the Nano Spray Dryer B-90 you are using is to check for a carved HP on the spray head.

A new design of the spray head and new nebulizers enhance the handling of the spray head. The new nebulizers enable the production of  particles with a higher throughput. The possibility to adjust the spray frequency, spray power and pump speed enable a better optimisation of the spraying process and the new Auto Stop function will protect both the product as well as the nebulizer lifetime by shutting down the spraying process when the nebulizer is detected empty.

The outlet temperature depends on the inlet temperature, sample throughput, sample concentration as well as drying gas flow rate. Changes in one of these parameters will either cause the outlet temperature to increase or to decrease.

Due to the atomisation principle, the viscosity limitation is 5 cps.

Nanosuspensions and nanoemulsions can be processed on the B-90 HP. The primary particle sizes should at least be 10 times lower than the nebulizer pore size and the other parameters need to fulfil the same requirements as for the solutions.

The Nano Spray Dryer B-90 HP Advanced in combination with the Inert Loop B-295 (& Dehumidifier B-296 Nano) allows to handle organic solvent based samples without risk of explosion.

The main difference between the Nano and the Mini Spray Dryer is in the particle sizes. The Nano Spray Dryer B-90 HP covers particle sizes from 200 nm to 5 µm while the Mini Spray Dryer produces particles from 2 to 60 µm. Other advantages of the Nano Spray Dryer such as the possibility to process very small sample amounts and to obtain relatively high yields (up to 90%) are also important differences to highlight.
