NSureIntroduction:

NSureOnline sulfur and nitrogen analyzers can be effectively used for continuous monitoring and analysis of sulfur content in refineries, natural gas pipelines, and purification plants, meeting product specifications from the most economical and practical perspective. They have won years of reputation for their stable and reliable performance, simple operation, and no need for too much manual involvement. It is an ideal choice for measuring the sulfur and nitrogen content of natural gas, liquefied petroleum gas, and oil products.

Measurement principle:

Total sulfur analysis:NSure Sulfur

Analyze compliance with standardsASTM D5453, D6667, ISO 20846，SH/T0689,GB/T 11060.8

UV Fluorescence Spectroscopy(UVF)Sulfur measurement technology is a fast and accurate method for quantitative analysis of sulfur, which can be used in1-2Complete within minutes as low as20ppbRapid determination of sulfur content up to a hundred levels.

R-S + O2 1000°C SO2 + combustion products

SO2 + hv→SO2*→SO2 + hν’

A certain amount of sample burns at high temperature, and all sulfur elements are converted into molecular statesSO2After being exposed to ultraviolet light, it emits fluorescence. The generated fluorescence is converted into an electrical signal proportional to the sulfur content in the sample by a photomultiplier tube and detected. Compared to the lead acetate paper tape method for measuring sulfur, the ultraviolet fluorescence method is more stable and does not require consumables, nor does it produce lead waste. This method is not availableXThe issue of matrix interference in radiation can provide accurate analysis results with lower sulfur content without the need for column switching or blowback. Because the detector used eliminates the quenching effects of carbon dioxide and water, you will be able to obtain more stable and excellent linear range analysis results.

Total nitrogen analysis:NSure Nitrogen

Analyze compliance with standardsASTM D4629, DIN 38409, TEIL 27, ASTM D5176, EN 12225

Applying accurate and precise chemical fluorescence detection(CLND)Technology,,Analytical instruments can be used1-2Complete within minutes from20ppbRapid determination of nitrogen content at the hundred level. Chemiluminescence is a rapid nitrogen measurement method that can be used for almost any liquid and gas sample.

R-N + O2 1000°C NO + combustion products

NO + O3→NO2* + O2→NO2 + O2 + hν’

A certain amount of sample burns at high temperature, and all nitrogen elements are converted intoNOMolecules. thenNOMolecules fully mix with ozone to occur React and emit light. The emitted light is converted into an electrical signal proportional to the nitrogen content present in the sample through a photomultiplier tube and detected.

NSureCharacteristics:

high-precision

Excellent repeatability and precision provide users with high-quality detection data. Good repeatability means that users can fully trust the data it provides. Users can confidently use their data to adjust process conditions to ensure that the total sulfur content in the products produced by desulfurization and blending processes meets the standard. The repeatability of an instrument is measured by its standard deviation.NSureLong term measurements of diesel, gasoline, and natural gas have yielded excellent repeatability results. In most applications, its repeatability over the full range is superior1%The accuracy is better than1%.

rapid analysis

NSureThe analyzer technology is advanced. From sample injection, to complete combustion of the sample, to analysis of the results, the entire process1It can be completed in minutes. Greatly saving time costs. And the analysis and detection process is simple and efficient - no sample residue will be generated
