A fluid delivery system including a filter for filtering solid particles from a liquid sample, the filter including a first filter member configured to filter solid media from a liquid sample, a second filter member fluidly connected to the first filter member, and a third filter member fluidly connected to a downstream end of the second filter member. The second filter member is configured to filter relatively smaller solid media from the liquid sample than the first filter member, and the third filter member is configured to filter relatively larger solid media from the liquid sample than the second filter member. In various aspects, the system includes a displacement-type plunger needle to draw sample fluid from a vial, a cantilevered carousel for rotatably supporting an array of sample holding vials, and a support for supporting the carousel. Method of using the fluid delivery system are also disclosed.

Fluid sample delivery system and method

Electrochemical analysis is performed by applying one or more time-sequenced voltage waveforms in a solution and measuring the resulting current in the solution. Raw data representative of the measured current parameters may be integrated based on one or more integration time intervals, and the raw data may be displayed in one or more three dimensional plots. The integrated data and the raw data may also be displayed in one or more two-dimensional plots. The raw data is stored for three dimensional displays and the integrated data is stored for two dimensional displays. Baseline correction is performed on the raw data and the baseline corrected data is displayed in one or more three dimensional plots and in one or more two dimensional plots. The raw data is stored at a rate between 100 Hz and 10 KHz.
