SULFUR ANALYZER CS3-02АGТ

Sulfur analyzer CS3-02АGT is intended for mass fraction of total sulfur determination in three samples of solid fuel simultaneously by combustion samples at high temperature and further coulometric titration.

 The Analyzer includes:

1) Electric tube furnace;

2) 3-channel unit for coulometric titration;

3) PC;

4) autotransformer.

CS3-02АGT Analyzer distinctive features:

• Combustion products of the burnt sample react with the electrolyte and cause changes of solution conductivity which is measured by the automatic titration unit. During the analysis the current-time curve is displayed on the monitor. All calculations computer performs automatically.
• Heating elements – silicon-carbide heaters.
• The low thermal conductivity of the high-temperature furnace insulation prevents analyzer’s control units from heating above the permissible temperature.
• The dryer - silica gel - is easy to restore.
• Minimum wear parts and chemical reagents.
• Minimum usage of distilled water.
• Samples are burnt in the furnace in the air flow. No oxygen is needed.
• The analyzer includes PC with Windows OS.
• Flexible settings and calibrations.

Functions of the analyzer parts

Electric tube furnace CS3-02АG provides heating and temperature regulation in the combustion chamber. In the upper part of the furnace a combustion chamber is situated. Furnace heating is provided by silicon-carbide heaters.

At the bottom of the furnace there is a control panel. The nominal temperature is controlled and regulated by the electronic heating controller.

The control panel enables:

• to set a working temperature of the furnace;
• to set the speed with which the furnace achieves the working mode;
• to set up to 10 working areas of trays delivery into the high temperature zone of the furnace with pauses in each position up to 4 minutes and automatic exit when the working program is over.
• to function in either automatic or manual mode of trays displacement towards the high temperature zone of the furnace.

If needed the furnace may be used for mass fraction of total sulfur determination according to the demands of GOST 2059-95, ISO 351:1996 using the chemical vessels and reagents which are not included into the supply kit.

 3-channel unit for automatic coulometric titration is intended for automatic coulometric titration.

Coulometric titration unit includes three electrolytic vessels, drier tubes and flowmeters for precise control of air consumption. Microprocessor unit controls titration process and data transfer to the computer.

Personal computer controls analysing, processes data received from the microprocessor unit  of the automatic titrationб makes calculations, calibrates the sulfur analyzer and gives the results of mass fraction of total sulfur. The results are stored in the computer memory and can be looked through or printed by operator.
