Data Processing:

• Stored data can be referenced in multiple ways, such as by date or specimen ID
• Screening of data
• The statistical treatment of data (mean, standard deviation, relative deviation)
• Signal comparison to the release curves of the analytical results

Flow Control:

The analyzer adopts high-precision electronic flow control technology with the Anti-Overshoot System for precise analysis gas flow control.

Catalytic Oxidation in the Copper Furnace:

• Prior to entering the Carbon detection cell, the analysis gas undergoes catalytic oxidation in the copper furnace to convert CO in the analysis gas to CO2, ensuring the detection of all CO and CO2 generated in the combustion process.
• Converts analyzed SO2 into SO3 and then absorbs SO3 to prevent air pollution.

Dust Filtration:

A specialized dust filter made of powder metallurgy materials is utilized, and automatically cleaned twice during each analysis.

Dual Combustion Furnace Infrared Carbon Sulfur Analyzer Self-checking Function:

• Automatically monitors and alarms the overall oxygen pressure at the entrance furnace, the analysis pressure at the rear of the furnace, and the dynamic pressure.
• Automatically monitors and alarms the on/off status of the high-frequency furnace.
• Automatically monitors and alarms the resetting of the cleaning device within the high-frequency furnace.
• The software provides a step-by-step self-checking function, including the monitoring and adjustment of infrared signals and the examination of valve movement on gas channels.
• The instrument can be checked part by part with the assistance of the software.

Weighting:

The electronic balance is connected to the computer for accurate specimen weighing. The weight data is automatically sent to the analysis software, and if necessary, the sample weight can be entered manually.

Time for Analysis:

• High-frequency induction furnace: Typical analysis time is 40-60 seconds.
• Tubular resistance furnace: Typical analysis time is 150-300 seconds.

Crucible:

• A high-frequency induction furnace uses a ceramic crucible with a diameter of 25mm and a height of 27mm.
• A tubular resistance furnace uses a porcelain combustion boat with a length of 87mm, width of 12mm, and height of 10mm.

Combustion Furnace:

• High-frequency induction furnace: 18MHz, Max 2.7KVA.
• Tubular resistance furnace: Maximum temperature of 1550℃; Max 4.4KW.
• The resistance furnace utilizes carborundum heating elements, with the power of heating controlled to extend the elements' life. The furnace's case temperature reaches the operating temperature in approximately 20 minutes.

Pre-treatment of the Crucible:

The ceramic crucible used in the high-frequency induction furnace can undergo pretreatment in the tubular resistance furnace. This dual-use of the tubular resistance furnace enhances work efficiency and analysis reliability.
