Episodic Data Capture

StellarNet SpectroChemistry systems include a configured spectrometer, a light source, and an appropriate sampling accessory (cuvette holder, probe, flow cell). SpectraWiz Software provides simultaneous window (with live spectra allows concentration calibration or loading of previously developed chemicals to be loaded for concentration display of unknown samples. Quickly save sample readings to log file for export and/or printing. Performs single wavelength linear PLS calibrations.

• Chemwiz concentration analyzer
• PLS calibration method save & recall
• Concentration display with rapid sample logging
• Episodic capture for kinetic studies

The Spectral-ID Application provides element identification via spectral database for qualitative analysis. Samples can be quickly measured and saved to log-file. Options allow customization of spectral search algorithms. Custom compound element libraries can be created or searched.

The Spectral-ID application has been updated to allow users to save sample spectra to a specified library, then later perform a real time search using unknown samples to look for matches.  This new feature works for Raman, NIR, or UV-VIS spectra using covariance mathematics to assign a correlation value and displays the top 10 library entries that qualify as a match.

The Spectral-ID application was originally created for elemental identification in plasma spectra using a PORTA-LIBS (Laser Induced Breakdown Spectroscopy) system.   A pre-configured library is included that can be modified by the user.

The new interface panel is simple and easy to use, allowing the user to click “Capture” and then ‘Analyze” to display matches.   The user can then click on any match to see its actual library spectrum and compare it to the captured one.  The powerful SpectraWiz software has a series of processing algorithms to compensate spectral baseline offsets and minimize effects due to off-axis scattering and fluorescence.

UV Monitoring Applications-
Display in units of watts for UVa, UVb, UVc, ratio UVa/UVb, Vis/Ir power Max Time in seconds till Erythema action and Max Time till Melanogenic action (per formulas specified on FDA website – U.S.Food and Drug Administration) Quickly save sample readings to log file for export and/or printing.

• UVa, UVb, UVc, UV a/b ratio, Total Irradiance
• Power UVb, Power VIR
• Te Erythema minutes
• U.S.FDA & European tanning algorithms
• Real-time display with rapid sample logging

Solar Match Monitor-
The SpectraWiz® software now includes a new solar match panel that is part of the Light Monitor application, that is used to characterize and classify light emissions for solar simulators.  The Solar Match Monitor application calculates spectral irradiance for each 100nm bin from 400-1100nm and compares the results to the ideal percent for each bin range per IEC/JIS/ASTM. The proximity of the measured data to the ideal values results in classification of the solar simulator lamp from A through D.  The Light Monitor also measures UVabc regions below 400nm using both U.S. and European standards.
