  9. KEY CONCEPT OF AI Block Diagram of AI

  10. Components of instruments for spectroscopy

  11. ELECTROMAGNETIC SPECTRUM Electromagnetic rays- ultraviolet, visible, infrared,x-ray

  12. MONOCHROMATORused for selecting single wavelength

  13. PRISM MONOCHROMATORFirst type of widely used, “scanning” wavelength selection devicesHistorically made of salts such as sodium chloride, etc.VERY delicate. Often subject to damage in humidity and wide heat ranges.Not widely used today in spectroscopy equipment.

  14. Optics - Filter Properties Long pass filters transmit wavelengths above a cut-on wavelength Short pass filters transmit wavelengths below a cut-off wavelength Band pass filters transmit wavelengths in a narrow range around a specified wavelength Band width can be specified Neutral Density filter is a nondiscriminant intensity reducing filter Absorption Filter is colored glass that absorbs unwanted light

  15. Optical filters Interference filters: Dichroic, Dielectric, reflective filters…….reflect the unwanted wavelengths Absorptive filters: Colour glass filters…..absorb the unwanted wavelengths

  16. Construction of Filters Filter components “glue” Single Optical filter Interference filters

  17. Optical filter evaluation optical filter(90o) slit/shutter light source detector monochromator SPECTROFLUOROMETER FOR ASSESSMENT OF OPTICAL FILTER TRANSMISSION

  18. Optical filter evaluation light source beam splitter (45o) reference PMT slit/shutter grating grating Detector PMT Optical filter (45o)

  19. Different shapes and sizes of sample holder

  20. DetectorsPHOTOMULTIPLIER TUBES

  21. DIFFERENT TYPES OF DETECTORS

  22. Different wavelengths require different detectors!!

  26. HOW WE STUDY......?

  27. PROJECTS IN AICPACT measurement projects Use of model process systems to devise and evaluate improvements in process control Robust calibration of spectral data using small data sets Process (low-field) NMR On-line liquid chromatography

  28. Project 2 - Robust calibration Objectives To investigate the signal processing and experimental design requirements to select the optimum combination of samples and variables that facilitate the development of robust calibration when only small data sets are available, and to identify the mathematical tools that enable the user to utilise only a minimum number of samples

  29. Project 3 - Process NMR Objectives To investigate the potential (at-line and on-line) and to develop a low-field instrument for process analysis To develop signal and data processing methods for overlapping signals To compare with other analytical techniques To conduct plant-based evaluations

  30. Project 4 - On-line liquid chromatography Objectives To understand the reasons for the current low level of usage of on-line LC To identify industrial applications with good ‘payback’ To identify areas of weakness and to establish ways of overcoming such aspects

  31. Trends for Analytical Instrumentation
