Teledyne Tekmar has introduced its Torch Combustion Total Organic Carbon (TOC) / Total Nitrogen (TN) Analyzer, utilizing a patent pending Static Pressure Concentration (SPC) for the analysis of TOC/TN using high temperature combustion. It contains a built-in autosampler with three vial rack choices and PC driven control, featuring 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.
