Abstract:
1. A device comprising: sampling means for introducing a sample solution into the device, the sample solution containing an analyte and interfering particulate matter, wherein the particulate matter is smaller in size than the analyte; integral filtering means sized to segregate the analyte by preventing the analyte from passing through the filter while allowing the interfering particulate matter to pass through the filter; diluting means for introducing a diluent into the device to mix with the segregated analyte to form an analyte suspension for analysis, the diluting means including means to pump the diluent through the integral filtering means in a first direction to wash the segregated analyte, and means to pump the diluent through the integral filtering device in a second direction opposite to the first direction, whereby the segregated analyte is mixed with the diluent to form the analyte suspension, spectrometer means to analyze the analyte suspension; a processing unit adapted to control the sampling means, diluting means and spectrometer means; and a waste removal means to remove the sample solution, diluent and analyte suspension from the device.
