Introduction
Spectrophotometers are widely used for Organic chemistry, Inorganic chemistry,Life sciences,foods, Medicine and health, Agriculture,Geology,Metallurgy and Environment etc.fields.
Functions and Applications
Photometric:Set the factor K, The direct calculation of k*a results. Measurement data can be saved.
Quantitative – Test total nitrogen by double wavelength method:
Double wavelength test method △A=MA1-NA2, can calculate the linear of inputted concentration C and △A,
Application: Test method of total nitrogen in water quality monitoring: △A=A220-2A275
Spectrum:Application for hexavalent chromium: The colored matter reacted from hexavalent chromium aqueous solution and diphenylcarbazide. One key for looking for the peak in spectrum function, looking in data sheet, as well. The position of absorption peak as picture 540nm. By marking the curve and quantitative to test the sample concentration.
Kinetics:Test the sample changes in a period, get △A/t, display the spectrum curve.
Multiple Wavelength Application: Neutral filter 10% measurement accuracy.
BIO: DNA/Protein test, test the sample’s protein and DNA concentration.
Save: Measurement data, scanning patterns are preserved at the host and disk U
One Key Upgrade: Plug the USB with upgrade program, switch on and go to upgrade menu, press no. key 1, the instrument will be upgraded automatically.
Features:
●Large LCD screen (128*64 Dots) with saving standard curve function
●Imported & Environmental Deuterium lamp, preventing from Ozone inhalation
●Adopted high-class grating with wholly hermetic light path design, to ensure the instrument has the super low stray light
●Real-time monitoring the lifetime of Deuterium lamp and Tungsten lamp with advanced system
●Pre-aligned design ensures the user can change lamps conveniently
●Wavelength calibration, wavelength setting, change lamp source and dark current calibration automatically
●With Si02 coating optical mirror, reducing the pollution from outside fully
●Optional PC Software to expand the applications to Quantitative, Multi-Wavelength and Kinetics
●Widely used for Organic chemistry, Inorganic chemistry, Life sciences, foods, Medicine and health, Agriculture,
Geology, Metallurgy and Environment etc. fields
Basic Fuctions:
1. Photometry (Basic); Test Abs., Transmittance by fixed wavelength
2.Quantitative
a. C Mode: EstablishC=K*A curve, test sample concentration
b. F Mode: Establish A=K1*C+K0, test sample concentration
c. Display and save curve, test data (V-1200).
