EV4011 Environmental Monitoring Instruments Syllabus:
EV4011 Environmental Monitoring Instruments Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
To educate the students on various instrumental methods of monitoring the quality of air,
water and soil.
UNIT I FUNDAMENTALS
Wet chemistry methods and their limitations-instrumental methods, selection of method- precision
and accuracy, error in measuring signals- quality control & assurance- sample preservation, sample
preparation and analyte isolation.
UNIT II SPECTROSCOPIC METHODS
Principles, techniques and applications of spectrophotometry, fluorimetry, nephelometry and
turbidimetry, Atomic Absorption Spectrometry (Flame, graphite furnace, cold vapour and hydride
generation), Atomic Emission Spectrometry (AES), flame photometry and Inducted Coupled Plasma
(ICP) – TOC Analyzer
UNIT III CHROMATROGRAPHIC METHODS
Principles, techniques and applications of GC, GC-MS, high performance liquid chromatography
(HPLC) and Ion Chromatography (IC)-hyphenated techniques for environmental contaminant (trace
organics) analysis, ICP-MS
UNIT IV ELECTRO AND RADIO ANALYTICAL METHODS
Principles, techniques and applications of conductometry, potentiometry, coulometry, AOX Analyzer.
amperometry, polarography, electro-capillary analysis, Neutron Activation Analysis (NAA), X-ray
Fluorescence (XRF) and X-ray Diffraction (XRD) methods.
UNIT V CONTINUOUS MONITORING INSTRUMENTS
Principles, techniques and applications of NDIR analyzer for CO, chemiluminescent analyzer for
NOx, fluorescent analyzer for SO2- particulates analysis- auto analyzer for water quality using flow
injection analysis. LIMS.
