Reaction Control and Monitoring

The ReactArray Workstation software was developed for Anachem by Aitken Scientific to provide full control of a Gilson sampler, pump and heated reaction racks. The software allows the creation of complex sequences of operations using simpler tasks like: aspirate, dispense, delay, wash needle, quench reaction, inject sample and rack temperature control.

After the multiple task sequences have been defined, ReactArray Workstation uses its scheduling algorithms to interleave the sequences and ensure optimal use of the available resources (sampler arm, syringe pump, HPLC).

The image to the right shows a typical ReactArray hardware setup comprising a Gilson 215SW liquid handler, 402 syringe pump and several racks.

The image to the left shows a bed layout on the sampler, with the task-sequences listed on the right and the interleaved schedule displayed graphically as a series of solid bars.

Through this display the user can appreciate the parallel nature of the optimised schedule that will keep the machine busy as much as possible.

The ReactArray Workstation software can also control Agilent™ HPLC equipment, and the ReactArray Data Manager software includes a chromatogram viewer, peak analysis algorithms and reaction profiling tools.
