Dekati® Dryer

Dekati® Dryer DD-600 is a particle dryer designed to remove water in real-time from the aerosol sample in air quality measurements. Since most ambient air particles are hygroscopic they grow as the ambient humidity increases. Traditionally this water has been removed from the particle sample after gravimetric collection by equilibration or heating of the sample. Both of these methods may also result in loss of other volatile components from the sample, whereas the Dekati® dryer only removes water. The operation of the Dekati® Dryer is based on a co-polymer Nafion® tube for removing humidity from the sample.

The Dekati® Dryer has been specially designed to minimize particle losses and maximize drying efficiency. The sample flow rate though the dryer is 30 lpm, so it is suitable for use with the ELPI™. The needed amount of drying air is 6 lpm, alternatively vacuum can also be used for drying.
