Description of key information

There is one study available analysing the granulometric properties of the test substance. The particle sizes were determined with the laser diffraction method (apparatus HELOS KF H0119) according to guideline ISO 13320-1. The median value of particle size is 482.96µm.

Additional information

The granulometric properties of thiourea were analysed with the laser diffraction method according to guideline ISO 13320 -1. Therefore the particle size distribution was determined using the particle size analysator HELOS KF (H0119) from Sympatec with a Sympatec RODOS dry dispersing unit. The test material was dried via dispersing and run in form of an aerosol fluent through a laser beam. The median value of particle size is 482.96µm.
