My samples are solids; can they be mixed prior to its analysis to make sure they dissolve?
The sample can be mixed prior to the analysis and or it can be homogenised if required. Homogenizing a sample presents a challenge in an automated system, as frequently a propeller or magnetic stirrer is not able to mix and dissolve the sample completely. Certain samples such as tablets must first be pulverized before the determination to release the substances of interest. Sample size reduction and homogenization can be carried out, for example, with the Polytron 1300 D homogenizer from Kinematica. To trigger the required actions, transfer commands are used to send defined three-digit numerical codes to the control unit of the homogenizer. Not only can the instrument be switched on and off, its speed can also be set in the range 7000…30,000 rpm. It is also possible to vary the speed of rotation within the method sequence to adapt it to the particular conditions. For instance, the sample can be disintegrated at 25,000 rpm with the subsequent determination taking place at 7000 rpm. If
