Additions (available May 2004)

The automated addition of liquid reagents into a reactor from a pump is a very common process. Classically, this is performed either volumetrically from a calibrated syringe or gravimetrically from a pump and balance combination. The first planned Lara™ module is an automated additions unit to compliment the Lara™ core system.

Where appropriate, the functionality of the Lara modules can also be achieved using third party equipment. Please contact our technical support team for assistance.

Crystallisation

Crystallisation is a common process by which products are isolated or purified. The size and size distribution of crystals can be very important and needs to carefully identified and controlled. To address this important area of process scale-up and development a Lara™ crystallisation sensor based on turbidity measurement is planned.

Where appropriate, the functionality of the Lara modules can also be achieved using third party equipment. Please contact our technical support team for assistance.

Liquid-liquid extraction

Liquid-liquid extraction is a work-up procedure used to recover products from reactions. The separation process takes advantage of the relative solubilities of solutes in immiscible solvents. Liquid-liquid extraction is very common where separations involve multiple components or where separation by distillation is ineffective or not practical. In adopting the liquid interface sensor approach a Lara™ liquid-liquid extraction module is planned for the future.

Where appropriate, the functionality of the Lara modules can also be achieved using third party equipment. Please contact our technical support team for assistance.

Automated sampling

Taking samples from a reaction at user defined time points in a chemical process allows the elucidation of important kinetic and mechanistic information and provides an instant snap shot of the current state of the process. Sampling can be performed either manually or with an automated system that removes samples at user defined time points often with on-line HPLC. This second approach offer some clear benefits in terms of unattended operation and will be developed as a module for the Lara™ unit in the near future.

Fractionation

Fractionation is a commonly used method of separation. It is often employed to investigate processes such as solvent recovery or recycling, mass balance and reflux studies. The facility to perform and control fractionation with Lara™ is planned for the future.

Where appropriate, the functionality of the Lara modules can also be achieved using third party equipment. Please contact our technical support team for assistance.
