 Analysis with software—powerful functions and easy to use

UVCON qualitative and quantitative data processing and analysis software with four regular functions, they are photometric measurement, spectrum measurement, quantitative measurement and dynamic measurement.

Four regular functions

Photometric measurement--for fixed wavelength measurements, it can be measured transmittance, absorbance and concentration at maxium of 10 wavelengths. It can be also measured at the same wavelength or modify the current settings separately, and printout or store the measuring data.

Spectral measurement with a spectral scanning and data processing capabilities,data processing functions have standardized, peak and valley detection, peak area calculation, map scaling, smoothing, derivative, mathematic caculate, scaler and other functions, and printout or store the graphic and data.

Quantitative measurement by three-wavelength baseline calculate and the average of repeated measuring to get the concentration, including of the application of methods and working curve settings. Application methods include the one-wavelength method, two-wavelength method, and three-wavelength method, and maximum of nine measuring times or the unit of concentration value input. Working curve settings include of the K coefficient method, single-point calibration and multi-point calibration, multi-point calibration with standard samples to measure or value of two kinds of keyboard input methods. Data processing function in any unusual spots removed. Working curves and measuring data can be printout or stored.

Kinetic measurement can be determined from the 1 second -10 hours of transmittance or absorbance of the time-varying recording intervals from 0.1-60 seconds, you can observe the fast response and changes. In the data processing functions have peak and valley detection and derivative operation.
