Aspects of integration
This hourlong webinar, “Overview of analyzer system integration,” covers analyzer roles, element types, shelter construction, hazardous area classification, degrees of area classification, rating impacts on packaging, purging, safety systems, HVAC, shelter utilities, headers and manifolds, mounting issues, wiring, sampling systems, continuous emissions monitoring, extreme climates, project management and system integration.
Design your sample system
This online article, “Analyzer sample system design basics for selecting the right options” by Morgan Zealear, covers design requirements and options, cylinder or bottle issues and station locations.
Gas chromatograph basics
This hourlong video, “Best practices and maintaining your gas chromatograph at optimal performance levels,” reviews baselines conditions, maximizing performance tracking detector response, control charts for response factors, detecting and interpreting peaks, optimizing performance and installation issues.
It's accompanied by nearby links to a webinar, “Calibration gases and how to calibrate a gas chromatograph correctly,” and to a video, “Validating the operation of your gas chromatograph.”
All types of gas analyzers
This webpage, “Understanding different analyzer types,” provides a glossary for all kinds of gas analyzers, including NOx, SO2, O2, CO, CO2, PID, NH3, H2S, PM2.5, VOC, gas chromatograph, in-situ, tunable-diode laser (TDL), and stack flue gas ammonia.
Manage DAQ, improve trust
This 19-page paper, “How can we improve trust in process analyzers?” by Hans Cusell of Hint Wout Last, shows how to integrate an analyzer maintenance and data acquisition management system (AMADAS) to reduce routine lab samples, but still increase trust in analyzer results.
pH meters, conductivity
This 18-minute video, “Using a pH meter—everything you need to know about pH,” demonstrates how to understand what’s being measured, choosing the right pH meter, how to use it, and how to calibrate different types of pH testers and meters.
This video is accompanied by a link to a 15-minute video, “What is electrical conductivity (EC/TDS)?,” which discusses its purpose, associated measurement units, and how to calibrate EC meter and probes.
Sampling, CGs, moisture
This 34-minute video, “Automatic analyzers and process control” by Dr. Rajeev Jain, school of studies (SOS) in environmental chemistry at Jiwaji University, covers sample handling, process gas chromatographs, electrochemical cells, negative-filtering analyzers and calibration and use of moisture analyzers.
O2 reduction potential
This 47-minute video, “Understanding ORP basics,” covers what’s required for an ORP measurement, and shows the difference between standard ORP measurement and a pH-compensated ORP measurement, how to improve the accuracy of ORP measurements, and the most common applications for ORP measurements.
Resources rerun
The previous version of this column, “A sampling of analyzers and accessories,” includes resources from Swagelok, Sick, Yokogawa, Mettler-Toledo and other organization.
