SYSTEM, METHOD AND COMPUTER PROGRAM PRODUCT FOR DETERMINING CALIBRANT SOLUTION CONCENTRATION

摘要

A system is provided for creating a diluted calibration solution out of a diluent supply and a calibrant supply. The system includes a restrictor, a flow controller, a pressure sensor and a processor having a module executable by the processor. The flow controller urges the calibrant supply through the restrictor toward the diluent supply. A pressure in the calibrant supply during urging is measured by the pressure sensor which is correlated by the processor to a concentration of the calibrant supply. Advantageously, calibration of the system can be avoided by using a draw of the diluent supply with a known concentration and comparing a ratio of the infusion and draw pressures to determine the calibrant supply concentration.
