KEY CONCEPT OF AI Block Diagram of AI
ELECTROMAGNETIC SPECTRUM Electromagnetic rays- ultraviolet, visible, infrared,x-ray
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.
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
Optical filters Interference filters: Dichroic, Dielectric, reflective filters…….reflect the unwanted wavelengths Absorptive filters: Colour glass filters…..absorb the unwanted wavelengths
Construction of Filters Filter components “glue” Single Optical filter Interference filters
Optical filter evaluation optical filter(90o) slit/shutter light source detector monochromator SPECTROFLUOROMETER FOR ASSESSMENT OF OPTICAL FILTER TRANSMISSION
Optical filter evaluation light source beam splitter (45o) reference PMT slit/shutter grating grating Detector PMT Optical filter (45o)

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
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
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
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
