An evaluation of the response speed performance of the GRIS.
(a and b) The real-time voltage curve at collection frequencies of 10 kHz and 100 kHz obtained by successively injecting air and deionized water at different flow rates. The flow rate ranges from 5 μL/s to 300 μL/s. (c) The purple dots represent the real-time voltage curve at a collection frequency of 10 kHz and a flow rate of 300 μL/s. The light-green dots represent the real-time voltage curve at a collection frequency of 100 kHz and a flow rate of 300 μL/s.
