It consists of two parts, the injection carousel and the flushing box with a pump. The enclosures were 3D printed using a Prusa i3 MK3S+ 3D printer. The entire system is driven by Arduino Mega microcontroller placed inside of the box on the sampling side of the capillary. The sample injection is ensured hydrodynamically by lifting the carousel with sample vials. Its movement is driven by two stepper motors, allowing it to move up and down and to turn in any direction. The autosampler can be programmed to operate autonomously through a keypad with LCD display accessible from the outer side of the cover box. Between
measurements, the capillary can be washed with the background electrolyte by applying pressure in the flushing box.Workplace Institute of Analytical Chemistry Contact Iveta Drobníková, drobnikova@iach.cz, Tel.: 532 290 234 Year of Publishing 2023 Electronic address https://hdl.handle.net/11104/0336571
