Investigation of the chemical form and physical form different substances and / or

摘要

Apparatus and a method are described for investigating polymorphs of a material, isomers of a material which allow different isomeric forms to be resolved, different hydrates/solvates and/or different salts of a material. The apparatus comprises an assembly ( 2 ) of reactor devices ( 6 ) arranged within a reactor body ( 8 ) which incorporates a heating/cooling block ( 10 ) and a stirrer block ( 12 ). A vessel support block ( 14 ) supports respective sample vessels ( 15 ) below each reactor device ( 6 ) for recieving material from the reactor devices. The apparatus includes a control unit ( 4 ) which includes a computer ( 16 ) which controls a robot for delivering materials to the reactor devices; a heating/cooling unit ( 18 ); a stirrer control unit ( 20 ); and a pressure unit ( 22 ) which controls the passage of material from the reactor devices ( 6 ) to the sample vessels ( 15 ).
