Chemiluminescence Detection for Nitrogen Containing Compounds Compared to Other Approved Techniques
3 Feb 2015Nitrogen monitoring is important for process control, regulations, and economic reasons. There are several techniques that can be used to monitor nitrogen, some of which can be time consuming, labor intensive, and may have waste disposal concerns. This application note examines using a high temperature combustion (HTC) Total Organic Carbon (TOC)/Total Nitrogen (TN) Analyzer with chemiliumunescence detection (CLD) to monitor nitrogen in samples. By using HTC TN, both TOC and TN can be determined simultaneously, analysis is completed faster, real time analysis can be done, and many matrices can be used.

Torch Combustion TOC Analyzer
Teledyne LABSTekmar’s TOC Combustion analyzer, the Torch, utilizes a patent pending Static Pressure Concentration (SPC) for the analysis of TOC/TN using high-temperature combustion. The Torch Analyzer contains a built-in autosampler with three vial rack choices and PC driven control. This features automated calibration and Intellidilution which automatically dilutes over-range samples to within the working calibration range. Maintenance is simplified by design allowing easy access to all areas of the unit. This instrument is best suited for the following Methods EPA 415.1, 415.3 and 9060A, Standard Method 5310B, EP 2.2.44, ISO 8245,EN 1484, USP 643 (Chapter 24), ASTM D2579, prENV 13370, AOAC 973.47
