Abstract:
A low-cost autosampler for surface plasmon resonance (SPR) biosensor platforms has been designed and applied for the determination of the mutual diffusion coefficient of ethanol in water. Its configuration is simple and based on a motorized carousel-type set-up. The sample loading process comprises a Z-drive, along with a syringe type analyte extractor. Furthermore, a commercial peristaltic pump is used to circulate the analyte through the microfluidic cell of the biosensor. A microcontroller connected to a PC provides control of the set-up. Theoretical aspects and experimental results are presented.
