Method for aspirating sample liquid into a dispenser tip and thereafter ejecting droplets therethrough |
摘要 |
A low volume liquid handling system is described which includes a microdispenser employing a piezoelectric transducer attached to a glass capillary, a positive displacement pump for priming and aspirating liquid into the microdispenser, controlling the pressure of the liquid system, and washing the microdispenser between liquid transfers, and a pressure sensor to measure the liquid system pressure and produce a corresponding electrical signal. The pressure signal is used to verify and quantify the microvolume dispensed and is used to perform automated calibration and diagnostics on the microdispenser.
