Process Analysis & Automation were commissioned by Biofocus Ltd. To design and build an automated multi-atomic absorption spectrometer system. Using four Thermo Electron SOLAAR AA spectrometers (with associated Gilson autosamplers), a Hamilton Microlab SWAP robot and a Kendro stacker, a fully automated and reliable workcell was produced. OVERLORD dynamic scheduler (Overlord2) was used control the workcell, with NetLORD used to control the four AA control PCs. We believe that this is the only fully commercially available automated AA system.
