Abstract
An automated computer controlled ground water system for monitoring and analysis for an analyte, has a sampling device in a well casing with a valve and sensor to provide a predetermined sample volume, a treatment assembly to prepare a calibration standard, a calibration assembly to provide a standard of known concentration and volume, an analytical assembly to analyze for analyte concentration, and a communication system to receive analysis data and transmit it to a cognizant agency.
Claims16
An automated computer-controlled field-deployable monitoring instrument system for collection and analysis of environmental contaminants and determining the concentration of an analyte of interest in ground water, industrial and surface water, comprising:
- diversion means dividing a water sample into first and second flow paths, said first flow path directing the water sample to a sample vessel for analysis, and the second flow path passing the water through a water treatment cartridge containing a sorbent media to eliminate the analyte of interest before introduction of water into the sample vessel,
- means to calibrate said instrument,
- a calibration assembly to add a standard of predetermined concentration of analyte to the water after it passes through a water treatment cartridge containing a sorbent media to eliminate the analyte of interest,
- a sample vessel to receive water from said single flow path to determine the concentration of the analyte in the sample water for either of the first or second flow paths, and
- means between the calibration assembly and the sample vessel to reunite said first and second flow paths into a single flow path.
A method for determining concentration of an analyte of interest in ground water and surface water, comprising:
- providing a field deployable automated computer-controlled monitoring system and instrument for determining concentration of an analyte of interest in ground water and surface water,
- calibrating said instrument,
- collecting and transporting a water sample to a preparatory treatment assembly,
- passing the water sample to diversion means to divide the water sample into first and second flow paths, said first flow path directing the water sample to a sample vessel for analysis, and the second flow path passing the water through a water treatment cartridge containing a sorbent media to eliminate the analyte of interest before introduction of water into the sample vessel,
- passing the water sample to a calibration assembly to add a standard of predetermined concentration of analyte to the water sample after it passes through a water treatment cartridge containing a sorbent media to eliminate the analyte of interest,
- reuniting said first and second flow paths into a single flow path, and
- passing the single flow water sample to an analytical assembly to determine the concentration of the analyte in the sample water for either of the first or second flow paths.
