SEC2000 UV/VIS Application

SEC2000-UV/VIS Spectrometer is simple and easy operation, compact and multi-channel spectrometer. In the light source the lens was incorporated to the light in a small module, it eliminated the need of fiber optics (Fig. 1). The main application of SEC2000 is for spectroelectrochemical measurements. Moreover, the combination with fiber-optics probe, introduced below, becomes possible the application in a wide experimental fields.Based on the examples below, you could find your own configuration!

Example of experimental configuration

Spectroelectrochemical measurement

ALS1200A Electrochemical analyzer and SEC-C Thin Layer Quartz Glass Spectroelectrochemical cell combination could be a compact configuration for spectroelectrochemical measurement. The oxidation of Potassium Ferrycianide at 800 mV vs Ag/AgCl was measured by absorbance mode using SEC2000 (Fig.2).

Combination with fiber optics

When you connect the optional fiber optics in SEC2000 Spectrometer, it could amplify the experimental application field. Some of the configurations are shown below.

Example 1
Reflection spectra measurement using reflection probe
Example 2
Reflection spectra measurement using reflection probe for immersion
Example 1 Example 2
Color analysis and absorbance of the material could be measured by reflected light spectrum. Fiber optic from light source and detector is embedded in a reflection light measured probe. Measurement using immersion probe could be directly with the immersion of the probe in a sample, without any previous adjustment.
 


Example 3
Fluorescence measurements using UV-LED light source
Example 4
Relative radiation light measurement
 
Example 3 Example 4
With an absolute spectral intensity irradiation at 90 degrees, the fluorescence of the sample could be measured. For this application a high power supply, as LED power supply, is recommended. Radiation, as a solar radiation, with a 180 degrees field of view, could be collected using Cosine Correctors at the extremity of the fiber optic connected to the SEC2000-UV/VIS.

Example of experimental configuration using SEC2000-VIS/NIR Spectrometer

When you connect the optical fiber or optical fiber probes in SEC2000 Spectrometer, it could amplify the experimental application field.

Reflection spectra measurement using transmission dip probe

Example 2

The transmition dip probe has a tip in the extremity of the probe, which is appropriate for the measurement of the spectrometry of the solution. Using the Visual Spectra Analysis software, it could be possible to save automatically the value of the spectrum variation and the spectrogram in a determinad wavelength.
