|The app utilizes the absorbance of light at a specific wavelength to calculate the concentration of a chemical compound. It establishes a linear relationship between absorbance and concentration through calibration, enabling accurate concentration determination. This functionality is valuable in various applications such as chemical analysis and quality control. It provides a reliable and efficient method for determining compound concentrations using spectroscopic analysis.
The “Load Method” button enables users to load a method file by default located in StellaproData/Concentration; containing slope and constant values for the linear equation specific to a wavelength. This information is essential for relating absorbance values to corresponding concentrations.
The Graph Window provides various graphs, including Scope mode, Transmission, and Absorbance. These graphs visualize the spectral data, raw data from the spectrometer (16-bit range), light transmission through the sample, and light absorption by the samples in absorbance units (Au). Additionally, strip testing enables time series analysis of the sample’s light absorbance at a specific wavelength. Users can input parameters such as time interval in seconds, the number of captures, wavelength, and the time point for slope calculation. This functionality allows for the evaluation of concentration changes over time, providing valuable insights for dynamic analysis and monitoring of samples.
|The Data window in the concentration app displays various information related to the loaded method file and concentration calculations. It presents details such as the loaded method file, the selected wavelength for analysis, the corresponding slope and constant values from the method file, the measured absorbance of the sample, and the calculated concentration based on the absorbance and the linear equation defined by the slope and constant. This window provides a comprehensive overview of the input parameters, measurements, and calculated concentration results, aiding in accurate analysis and tracking of concentration values.
|The Method Builder Window in the concentration app allows users to create a calibration method file using a linear line equation.
