摘要
A sampling system for measuring the presence and concentration of inorganic ion species, including, metals, metalloids and non-metals, in a liquid solution including a first sampling unit. The first sampling unit includes a potentiometric subsystem configured to gather environmental metrics of the liquid sample, a preparation subsystem, coupled to the potentiometric module, the preparation subsystem being configured to prepare and isolate contaminants of concern in a flow of a liquid sample into metal, metalloid, or non-metal ionic forms; and a voltammetric subsystem selectively coupled to the preparation subsystem, potentiometric subsystem and a sample source, the voltammetric subsystem being configured to identify and determine a concentration of metal, metalloid, or non-metal ionic species through stripping voltammetry. The system is configured to compare a value of a stripping signal of the sample with a predetermined value to determine if dilution of the sample is required.
