Hand-held thermal-regulating fluorometer [1]

  • Portable, low cost fluorometer using blue LED as excitation source and integrating photo detector as detection element
  • Sample can be thermal regulated using infrared heater and infrared thermometer
  • Software only regulate temperature and changing integration settings, data is not processed
  • Tested using FAM fluorescent dye
  • No comments about performance or accuracy of the fluorometer


Versatile portable fluorometer for time-resolved luminescence analysis [2]

  • A portable, but not low cost, fluorometer for time resolved luminescence analysis
  • Uses xenon flashlamp with filter as excitation source, and photomultiplier tube with filter as the detection device
  • This device claimed to have better SNR by about 1 order of magnitude than state of the art commercial spectrometer at the time of the writing
  • Intended to detect drugs such as tetracycline
  • Could be used to test different compounds due to the multi wavelength light source
