| Software Details: |
- Advanced windows multi document interface.
- Simultaneous display of different measurement modes on one screen toggling between different measurement modes can be achieved instantaneously.
- Spectrum Measurements: Up to 10 spectra and time course curves can be measured and recalled in memory with data handling of mathematic calculation, logarithmic calculation, reciprocal calculation, smoothing derivative, 1st to 4th abs to/ from % T conversion and peak pick.
- Multiwavelength photometry can measure the absorbance and transmittance of samples at 1 - 10 wavelengths, average the measured values and make calculations based upon the results if an equation is entered.
- Multichannel measurement with color display and printout and various capabilities for data processing . this module allows manipulation of information and data display from spectra calculations to various transforms such as 1st to 4th derivative smoothening and logarithms. The data output peak pick and data pick is also available.
- Quantitative determination. This module has more data power, 24 standards can be entered, determination of 1st - 4th order std curves can be achieved. Besides, creation of a standard curve, accurate measurement can also be done on samples with non linear absorbance, the quantitative methods use single wavelength, two wavelength coeffiecient two wave length, three wavelengths and 1st - 4th derivatives.
- Kinetic measurement can monitor the changes of absorbance and transmittance against time at 10 different wavelengths and, data display, from calculation of curves to various transforms such as 1st to 4th derivative, smoothing logarithms etc.
