Abstract
Disclosed herein are systems and methods for measuring one or more target analyte concentrations, particularly peroxyacid compounds, in a process solution, for example, in industrial and commercial water. These systems and methods include automated methods to measure the target analyte concentration in the process solution. The methods have the advantage of providing a large dynamic range for measurement and can be used in a wider range of process solutions.
Claims23
An automated sensor comprising:
- a sample treatment system comprising a sample pump and a sample filter, wherein the sample pump is for pumping a sample into a reaction manifold, wherein the sample comprises an analyte;
- a first reagent pump for pumping a first reagent into the reaction manifold;
- the reaction manifold for mixing the sample with the first reagent, the reaction manifold being in fluid communication with the sample treatment system and the first reagent pump;
- a measurement chamber in fluid communication with the reaction manifold;
- a first detector in fluid communication with the measurement chamber for detecting a property of the analyte in the measurement chamber;
- a waste line for removing waste from the measurement chamber and having a fluid communication to the measurement chamber;
- a waste pump in fluid communication with the waste line for removing the sample and the first reagent from the sensor;
- a rinse line in fluid communication with the measurement chamber;
- and
- a controller communicatively coupled to the sample pump, the first reagent pump, and the first detector, wherein the controller controls the sample pump to set the flow rate of the sample, controls the first reagent pump to set the flow rate of the first reagent, and receives data from the detector to detect the property of the analyte.

A method for quantification of a target analyte concentration in a sample comprising:
- flowing the sample through an analyzer comprising a reaction manifold, a measurement chamber comprising a detector, and a waste line;
- flowing a first reagent through the analyzer to contact the sample;
- detecting a property of the target analyte and calculating the concentration of the target analyte in the sample;
- rinsing the analyzer by flowing a rinse solution through the analyzer;
- and
- draining the analyzer by pumping the sample, the first reagent, and the rinse solution out of the analyzer.
