Main Modes of Operation

Registration of absorption spectra
Measuring absorbance (or transmission) at selected wavelengths. Measuring absorption and transmission spectra. Operations with graphic spectrum representation (changing the scale, marking points of extremum, comparison of spectra), mathematic spectra processing, including export of data arrays to outside developers' programs (MS Excel, MathLab, etc.)
Determining concentrations
Automatic construction of calibration curve from several series of measurements of standards. There are provisions for selective repetition of measurement of a particular standard in the user's specified series. Export of the data array to other programs for a detailed statistical calculation of calibration coefficients.
Determining speed of reactions
Construction of kinetics curves for several samples simultaneously. Flexible conditions of the measuring procedure start - time of the initial delay is set by the user. Kinetics calculations as a function of the selected time interval. Export of data.
Data storage.
Software allows data saving to the computer hard disk. A special database is maintained to facilitate search of the required entries.
Fast and convenient determination of optical densities at one or several wavelengths

Measurement of absorption and transmission spectra with a specified level of smoothing

Work with a graphic image of the spectrum - rescaling, searching for extrema, etc.

Automated plotting of calibration curves (graduations) and determination of concentrations

Calculation of calibration coefficients from several series

Plotting of kinetic curves (including those for multiwave kinetics)

Mathematical processing of results, formula constructor

Printing the results in a simple and understandable view

Data export to other programs, for example, to MS Excel

Оптическая система
Регистрация всего спектра, а не отдельных линий, как в случае использования фотоумножителей, открывает практически неограниченные возможности по анализу сплавов самых разных типов на одном приборе. Для решения задач, требующих коротковолнового ультрафиолета, полихроматор продувается аргоном или азотом. Расход газа составляет 0.05 л/мин., что существенно меньше расхода на продувку штатива. По сравнению с вакуумной, продувная конструкция более легкая и дешевая, она проще и надежнее в эксплуатации при этом обеспечивает такие же спектроскопические возможности прибора.
