  • Methods
  • However, with the introduction of multicomponent methods, UV spectrophotometry showed an astonishing capability in the quantitation of compounds in mixtures without previous separation [ 8 - 11 , 15 - 17 , 24 ]. (ijpsonline.com)
  • Stability
  • For ASP stability monitoring in tablets, ultraviolet (UV) detector has been found to be fit for the purpose as it is suitable to accurately measure in the microgram order, therefore most of the methodologies reported previously employed high performance liquid chromatography (HPLC) technique [ 7 , 13 , 21 - 23 ].

  • light
  • The plate is examined under ultraviolet light at a wavelength of maximum output at about 254 nm, then left in a chromatographic chamber containing some iodine crystals until spots appear. (who.int)
  • Hill worked on the properties of ultraviolet light, developing analytic methodology, and, in collaboration with her husband Carl McClellan Hill, developing ketene synthesis which supported the development of plastics. (wikipedia.org)
  • To take readings in the ultraviolet or visible range, a hydrogen or tungsten lamp was used, focusing light into the entrance slit. (wikipedia.org)
  • samples
  • Quartz or mirror-based optics can be used for studying samples from the ultraviolet (UV), down to 200 nm, to the near infrared (NIR) up to 2100 nm. (wikipedia.org)
