A powerful benchmark for nitrogen and sulphur analysis

Dec 20 2019

TE Instruments’ XPLORER-NS is one of the most popular instruments worldwide for the analysis of nitrogen and sulphur in (petro)chemical samples. It combines powerful combustion capacity and outstanding sensitivity within a small footprint.  A true multi-matrix analyser that enables fast and accurate determination of total nitrogen and total sulphur concentrations in liquid, solid, gas, and LPG samples. Easy to upgrade with advanced sample automation systems for practically all sample matrices due to its modular design.

The XPLORER-NS analyses nitrogen and sulphur simultaneously. Analytical results of a sample containing both elements are determined during a single injection. Samples can be introduced by either direct injection or boat-inlet system and are oxidized at high temperature in the advanced combustion environment. A complete, soot-free sample combustion creates the perfect condition for extremely accurate analyses, even at trace levels (<1 ppm). The formed nitrogen oxide (NO) and sulphur dioxide (SO2) molecules are detected according to chemiluminescence and UV-Fluorescence technique. The XPLORER-NS fully complies with all relevant international test methods for total nitrogen and total sulphur analysis, such as the ASTM D5453, ASTM D4629, ASTM D5762, ASTM D6667, ASTM D7183, ASTM D7184 and ISO 20846.

TE Instruments continuously innovates its existing product lines, which leads to the development of new solutions that fit the specific application needs of operators in the petrochemical and refining sectors.
