Instrumentation for Uv-Vis Spectrometry:

Presently a  huge range of instruments  are available  for  making  molecular  absorption measurements  within  the  UV-visible  range.  These  vary  from  easy  and  inexpensive machines  for  routine  work  to  extremely  sophisticated  devices  that  could  be  used  for specialised work and of course the routine jobs also. Therefore, the primary components of these instruments remain the similar.  The five necessary components of UV-VIS instruments are as follows

• A stable radiation source
• Wavelength selector
• Sample holder
• Radiation detector or transducer, and
• Signal processing and output device
