This spectrometer requires either a LabQuest interface or Logger Pro 3 software to collect data. Light Sources: Incandescent white bulb, approximately 8000 hour lifetime, LED-based, approximately 100,000 hour lifetime Photometric Accuracy: ± 13.0% (as determined with nickel sulfate standards from 0.1 to 1.0 A.U.) Wavelength Accuracy: 3.0 nm (at 650 nm) and 7.0 nm (at 450 nm) Optical Resolution: 4.0 nm (as determined with 656 nm hydrogen emission spectral line FWHM) and 25 nm (as determined with 486 nm hydrogen emission spectral line FWHM) Reported Wavelength Interval: 1 nm between reported values (collects 570 values) Support for fluorescence (two excitation sources centered at 405 nm and 500 nm) Emerging light goes through a high-quality diffraction grating, then the diffracted light is collected and sorted by the CCD array detector. Light from the LED and tungsten bulb light source passes through a solution. For detailed emissions analysis, including hydrogen emissions, we recommend the Vernier Emissions Spectrometer. Measure emissions of gas discharge tubes, flame tests, or other light sources, using the SpectroVis Optical Fiber accessory (sold separately). Perform colorimetric or fluorescent bioassays Then, in order, plug the spec power cord into an outlet, plug the other end into the spectrometer where it is labeled POWER, and plug in the USB port. Perform equilibrium studies of absorbance vs. The absorbance of a sample is given as A log. Measure absorbance, percent transmittance, emissions spectra, or fluorescenceĬonduct kinetic studies of absorbance vs. concentration, the absorbance by a solution is directly related to the concentration of the.

With its two different excitation wavelengths, SpectroVis Plus can quantitatively measure the fluorescence spectra of many compounds, such as chlorophyll, fluorescein, GFP, and more.Ĭonnect SpectroVis Plus to a LabQuest or a computer running Logger Pro using a standard USB cable (included), and see the results in full color. Logger Pro (computers), EasyData or DataMate (calculators). Data will be collected on Logger Pro and plotted on Excel to form an absorbance vs concentration graph. However, in this analysis, dilutions will be made using a specific stock solution and an unknown solution will be given. Once the peak wavelength is determined, you can easily determine the concentration of a solution (Beer’s law) or monitor rates of reaction. For the quantitative analysis, the SpectroVis Plus and Logger Pro will also be used. Having a CCD array spectrometer/fluorometer combination is now affordable for each of your lab stations! Array spectrometer technology allows you to collect a full wavelength spectrum (absorbance, percent transmittance, or intensity) in less than one second.
