Understanding alarm management
This nine-page PDF whitepaper discusses the pitfalls of alarm management and how mistakes in the past have been quite costly. It then addresses these mistakes and gives an overview of proper alarm management.
How to control a process with long dead time
A process with a large dead time presents a special challenge for a controller -- any controller. This short paper explains how to get the best control of large dead time processes.
Theory and practice of pH measurement
This 43-page guide covers the basic mechanism of pH measurement, the structure of the sensor and its fundamental limitations, and also provides installation, maintenance and troubleshooting guidance.
Level measurement of bulk solids and powders

Tracing the accuracy of calibration gases
Calibrating your instruments using specialty gas will only yield results as accurate as your gas mixture. This three-page white paper discusses analytic traceability and how it relates to gas mixture accuracy.
Management of Change or Change of Management?
Management of Change processes are subject to a variety of pitfalls. This paper highspots a variety of implementation issues that can frequently undermine the success of MOC processes.
Continuous PHA Revalidation
A process hazard analysis must be revalidated every five years. This paper discusses the merits of a new approach aimed at increasing the effectiveness of PHAs, called Continuous PHA revalidation.
Facility Major Risk Survey
This 8-page primer describes a method for identification of major acute risks in existing process facilities that can potentially affect on-site and off-site populations and for prioritization of mitigation methods.
