Systems and apparatus for reducing signal noise due to pump oscillations |
abstract |
A system reduces unwanted noise due to pump movement. The system includes a pump including a non-conductive piston extending into a pumping chamber for pumping the sample fluid along an analysis fluid path, a wash chamber, and a seal fluidly separating the pumping chamber from the wash chamber. The system also includes a wash path supplying a wash fluid from a wash reservoir to the wash chamber, an electrical conductor electrically connecting the analysis fluid path to the wash fluid path, and a ground conductor electrically connecting the electrical conductor to ground via a resistor. The electrical conductors and resistor combination between the chambers reduces unwanted noise in the conductivity detector due voltage potentials between the eluent and wash chambers created as the piston moves between the chambers. |
