Main features:
Adopt the holographic blazed grating, double beam C-T Optical structure, high resolution, low stray light, high accuracy, good stability.
The microcomputer control, automatic recording, a recording paper in the printer can print spectra, test data and operation parameters.
The light source automatic conversion (available at 294nm ~ 364nm Any set)
The spectral processing ability strong.
The characteristics of the software:
The information storage capacity, convenient storage.
The software provides four channels of storage of temporary, can be covered and overlapping the transmittance, absorbance, absorption and logarithmic energy spectrum scanning, transmittance and absorbance spectra can be easily transformed to map can map and map, map and line number four operations, derivative operation.
Peak detection, map zoom - ease.
The time scan kinetic study.
The quantitative analysis provides concentration linear regression method, provides a method of undetermined coefficients and coefficient of input method for curve fitting and eliminating abnormal points, determination of 2 and 3 lambda lambda 3, lambda provides automatic wavelength setting and provides 10 sets of data are available for users to select wavelength.
The software provides a fixed wavelength and multi wavelength test, and notes on the test data, provides the convenience for the same sample multi user test, multi wavelength test can be carried out as many as 20 wavelength test.
Can be easily set to map the storage parameters of the instrument test conditions.
The printer can print, map parameters and parameters and map and data printing, parameters and printing data and curve printing.
