ANS8820 Carbon & Sulfur Analyzer

ANS8820 carbon and sulfur analyzer rapidly detects the content of carbon and sulfur elements in Metals (such as Steel, Cast Iron, Copper, Nickel, Titanium and alloys), Ores, Cement, Ceramics, Carbides, Minerals, Coal, Coke, Oxides, Oil, Ashes, Catalysts, Lime, Gypsum, Soils, Rubber, Leaves, Soot, Tobacco, Waste, Sand, Titanium, Glass and many others.


1. Infrared Detection Unit
Circuit Design: The modularized design with double CPU for the whole frame is divided into the upper and lower levels; electronic circuits are integrated stably and reliably.Multilevel hidden-type isolated circuit is employed so that it is free from HF interference.
Power: The linear close-coupled modular power block ensures stable output without fault.
Light source: The platinum infrared light source has lasting caloricity and efficient spectral property.
Analysis cell: The gilded carbon & sulfur analysis cell is fit with the high precision TSC infrared detector (10-11).Double-carbon cell or the double- carbon & double-sulfur cell can be fit at the client's request.
Motor: The special-purpose aviation modulation motor is applied with satisfactory thermal stability; life expectancy exceeds 100,000 hours.
2. Analytical gas path system
Gas path: The high precision flow controller ensures the stability of gas flow as well as the gas intake system (such as electromagnetic valves, unions, cylinder hoists). It's used for automatic leakage detection.
Dual standard correction for solids and gases
De-dusting unit: The combustion head self-cleaning device is used to reduce the influence of dust on the result of analysis.
Ash removing system is also equipped for the inlet and a 0.4 ┬Ám sub-micron metal filter secures thorough separation of dust from gas.
3.Power software
WIN2000/XP Full Operation Interface is easy to learn and convenient to operate.
The completely functioned software is competent for more than 40 functions such as curves/data production and memory, deduction of blankness, preset of parameters, selection of paths, mathematical statistics, correction of results, revision of breaking points, comparison of curves, systematic diagnosis and auto/manual printing of analysis results, etc.
Dynamic data integration, linear/error self-correction, or the client is free to make adjustment of the working curves accordingly.
There are eight passageways for either carbon or sulfur, so the client can choose different passageways based on the different materials and contents of samples.
Dynamic display of various real-time record of data and curves of carbon or sulfur release during the analysis.
Surveying the width of linearity is expandable.
