Instruments

• Agilent CE-UV ( Capillary electrophoresis instrument )
  

  "CE with UV detection is appropriate for the quantitation of analytes yielding chromophores, as shown for the analysis of tablets containing amphetamines."

• Coherent Innova 300 FreD Ion Argon Laser System ( Irradiation system )
  

  "The Innova® 300 FRED™, using the technique of intracavity frequency-doubling (second harmonic generation) with b-Barium Borate (BBO), produces continuous wave (cw) laser light in the 229.0 to 264.3 nm region. Output is provided at six different wavelengths in this deep-UV region, with specified output powers up to 100 mW."

• HPLC-UV/FL System ( High performance liquid chromatography instrument )
  

• LS 50B Luminescence spectrometer ( Plate luminometer )
  

  "Sources for the PerkinElmer Luminescence Spectrometers are pulsed Xenon discharge lamps (7.3 W average power at 50 Hz). This reliable source produces very little ozone or heat but provides remarkable sensitivity due to its peak intensity exceeding 1 KW! On most LS Series instruments the detector electronics are controlled so that delay and gate time can be varied to measure phosphorescence between source pulses."

• Microdialysis sampling system ( Dialysis system )
