Dual Combustion Furnace Infrared Carbon and Sulfur Analyzer CS-3500G which can be used to detect the content of carbon or sulfur in metals, alloys and organic materials.

CS 3500G Dual Combustion Furnace Infrared Carbon and Sulfur Analyzer, is a high-end combined infrared carbon and sulfur analyzer of world-leading technology.

Due to the diversity of specimens of users and analytical methods, the instrument is equipped with two sets of sample pre-treatment units, i.e. high frequency induction furnace and tubular resistance furnace. The resistance furnace and the high frequency induction furnace share the same infrared detection system for the detection of content of output gases to be detected. It is easy to switch between the two furnaces.

CS 3500G Dual Combustion Furnace Infrared Carbon and Sulfur Analyzer can be used for the detection of carbon and sulfur in a wide range of specimens, such as steel, cast iron, alloy, metal ore, ceramics, cement, lime, rubber, coal,coke, refractory, carbide, graphite, oil, catalyst, soil and other solid materials.

Scope of analysis:

High frequency induction furnace (500mg sample): low carbon: 1ppm ~ 0.1%, high carbon: 0.1% ~ 5%

Low sulfur: 1ppm ~ 0.3% high sulfur (150mg sample): 0.3% ~ 30%

Tubular resistance furnace (500mg sample): carbon: 0.01% ～ 20%

Sulfur: 0.005% ～ 20%*

Note: The number and size of measuring cell can be selected according to the sample content requirements of users.

The analysis range can be extended to 100% by changing the sample weight.

Analysis accuracy:

High frequency induction furnace: low carbon: 1ppm or RSD ≤ 1%, high carbon: RSD ≤ 0.5%

Low sulfur: 1.5ppm or RSD ≤ 1.5%, high sulfur: RSD ≤ 1.5%

Tubular resistance furnace: low carbon: RSD ≤ 1%, high carbon: RSD ≤ 0.5%

Low sulfur: RSD ≤ 1.5%, high sulfur: RSD ≤ 1.5%

Note: The standard deviation of standard sample shall prevail.

Sensitivity: 0.01ppm

Analysis time:

High frequency induction furnace: 40-60 seconds

Tubular resistance furnace: 150s ~ 300s

Sample weighing:
