A home-made gradient microbore high-performance liquid chromatographic (HPLC) system was designed using two Varian 8500 stepper motor-driven syringe pumps. The pump delivery of the mobile phase solvents in the 10 pl/min flow-rate range is quite pulsed in nature. Static and dynamic mixing devices wer
