Software Details

  • Innovative Microsoft windows multiple papers program.
  • Multiple screen of different statistic ways on one screen toggling between different statistic ways can be carried out instantly.
  • Array Measurements: Up to 10 spectra and time course shapes can be calculated and remembered in storage with information managing of mathematic computation, logarithmic computation, mutual computation, removing mixture, 1st to 4th abs to/ from % T transformation and high choose.
  • Multiwavelength photometry can evaluate the absorbance and transmittance of products at 1 - 10 wavelengths, regular the calculated principles and make computations based upon the results if an situation is joined.
  • Multichannel statistic with shade screen and printout and various features for computer . this component allows adjustment of information and information screen from spectra computations to various changes such as 1st to 4th mixture smoothening and logarithms. The information results high choose and information choose is also available.
  • Quantitative perseverance. This component has more information power, 24 requirements can be joined, perseverance of 1st - 4th order std shapes can be carried out. Besides, generation of a conventional contour, precise statistic can also be done on products with non straight line absorbance, the quantitative methods use single trend size, two trend size coeffiecient two trend size, three wavelengths and 1st - 4th types.
  • Kinetic statistic can observe the changes of absorbance and transmittance against time at 10 different wavelengths and, information screen, from computation of shapes to various changes such as 1st to 4th mixture, removing logarithms etc.
