  4. Pasco Wireless Spectrometer • Wireless spectrometer at an affordable price • Chemistry • Biology • Physics • How it works? • Light from the LED-boosted tungsten light source passes through the solution and a high quality diffraction grating. • The CCD array detects the light for collection and analysis

  5. Advantages • Bluetooth and USB connectivity enables use with tablets and computers • Can measure: • Intensity • Absorbance • Transmittance • Fluorescence

  6. Free Software • Available for Windows and Mac computers • Free Apps for IOS devices and Android tablets • Free software walks you through the process of calibration, performing a full spectrum scan, determining optimum wavelength for study, and concentration and kinetics experiments

  7. Software Applications • Analyze a solution in terms of: • Intensity vs. Wavelength • Absorbance, Transmittance, and/or Fluorescence vs. Wavelength • Analyze a solution’s concentration • Analyze a solution’s reaction over time
