10 Water Analysis ApplicationUsing a Reverse Color Method16. To save the adjustment correction factor to the test method, press the Save Test functionkey and overwrite the existing test method or save as a new test method.17. Press the Run Test function key.When running a test with an adjustment correction factor in use, the display will show(1pt Adj) next to the test name.Using a Reverse Color MethodReverse color methods are recognizable as those which have a negative factor (i.e., the slope ofthe calibration curve is negative). For these methods, the chemistry used to make themeasurement causes a dark color (high absorbance) for very low concentrations of analyte,and an increasingly lighter color (lower absorbance) as the concentration of the analyteincreases. Chemical Oxygen Demand (COD) is an example of a test that is often run using areverse color chemistry.Thermo Scientific Orion AquaMate 7000 Vis and Orion AquaMate 8000 UV-Vis 45
