PROCESS ANALYZERS 101
This 45-minute video, "Continuous Gas Analyzers," was presented at the Siemens Industry 2013 event. The presentation covers analyzers, sample systems, sample points, defining requirements and budgets, and understanding overall processes.
WEB-BASED ANALYZER LIBRARY
The Free Technical Engineering Library includes an Analysers section covering emissions, monitoring, oxygen, pH, humidity and oil water, while the Analyser Sample Systems section covers sample conditioning, modular systems and grab systems. Each has dozens of articles and resources. Check out the Analytical Instrumentation Library and the Analyser Sample Systems Library.
REZABEK ON MAINTENANCE
SEVEN DEADLY ANALYZER SINS
This technical paper, "The Seven Deadly Sins of Process Analyzer Applications," offer examples and quantitative information based on historical experiences of analyzer engineering and sample handling.
GAS CHROMATOGRAPHY BASICS
This 14-minute video, "Fundamentals of GC—Introduction and Overview," describes gas chromatography (GC) basics, main components of a gas chromatograph and common applications where a GC is used.
ONLINE CHEMICAL TEXTBOOK
The web-based University of Michigan Chemical Engineering Process Dynamics and Controls Open Textbook is a student-contributed, open-source text. The section on Composition Sensors covers photometric and electrometric analyses, chromatography, mass spectrometry, thermal conductivity of gases, physical property measurements and other topics.

pH, ORP, CONDUCTIVITY VIDEO
This video from Control's Back-to-Basics series explores wet chemistry measurements; shows how density, pH, ORP and conductivity are deceptively simple and similar; and covers density analyzers, too. Control former editor Walt Boyes demonstrates how to understand and differentiate between these three measurements.
LIMITATIONS AND ADVANCES
The "analyzer resources" webpage at the Modeling and Control website is compiled by Greg McMillan, links to other articles, and describes trends making analyzers more maintainable.
MODELING AND CONTROL
ONLINE ANALYZER INTRODUCTION
The Instrumentation for Process Control online textbook, located at the free Process Control Education website and hosted by McMaster University, includes Chapter 2.5, "Onstream Analyzers," which provides an introduction to analyzers and sample systems.
SPECTROSCOPY AND SEPARATION
This technical paper, "Combining Spectroscopy and Separation Science in Process and Emissions Monitoring," shows how auto-carrier, frontal-elution chromatography in conjunction with a process UV spectrometer allows rapid online analysis of trace components even in complex streams.
