A sample is injected into a flowing carrier solution stream that is forced by a peristaltic pump. The injection of the sample is done under controlled dispersion in known volumes. The carrier solution and sample then meet at mixing points with reagents and react. The reaction time is controlled by a pump and reaction coil.
An additional patent has been filed for in 2014 by Salamey. The pump was originally designed as an improvement to peristaltic and diaphragm pumps as they were susceptible to fracturing of the pumping chamber with use due to their flexing of plastic parts. Inductive pumps were found to be an improvement to accuracy and length of service before ...
