Abstract:
Sulfur chemiluminescence detection (SCD) is a key technology for the petroleum industry because it is sensitive and selective to sulfur. Most petrochemical QA/QC laboratories utilize multiple GC-SCD instruments for testing sulfur content of flares, process streams, and final products, and yet the SCD’s capabilities and limitations are often misunderstood despite decades of deployment. This presentation will cover the fundamentals of the detector response curve, how its features translate into concepts such as “sensitivity” and “linearity”, and how those concepts intersect with one of the SCD’s most important features – “equimolarity”. Understanding what these figures of merit mean, how they’re used, and how they impact calibration will help users with both method development and troubleshooting for their GC-SCD systems. Though this topic can be deeply technical, this presentation aims to simplify these abstract concepts and is intended for all laboratory personnel.
