Homogenisation of soil and clay samples in preparation for environmental analysis of poly aromatic hydrocarbons (PAHs). The system had to loosen complex clay samples and allow pre-analytical extraction of PAH's.
ALcontrol required a special mixing system that could rotate 24 sample tubes in a powerful heated ultrasonic bath. The unit had to allow the samples to be easily placed and removed on a rotisserie inside the ultrasonic tank.
Grant's skills and technology
Our understanding of mixing, heating and ultrasonics, combined with experience in sample preparation, led to the development of a feasibility model followed by a production sample tube rotator within a temperature-controlled ultrasonic bath.
The team developed the concept and prepared a detailed proposal. A prototype was constructed, tested and approved, and the system went into production.
