DM1260 ASTM D4294 Model X-ray sulfur analyzer machine
Product Description
The X-ray fluorescence sulfur analyzer is a quantitative analysis instrument used in industries such as petroleum, coal, building materials, metallurgy, and mining. It is mainly used to measure the total sulfur (S) content in materials such as petroleum products, coal, cement, and carbon black. Due to its use of physical analysis methods, it has the advantages of fast analysis speed, no need for complex sample pre-treatment, high accuracy, low human error, low labor intensity for operators, and no pollution. Therefore, it has been widely used and has largely replaced chemical analysis methods.
The DM1260 X-ray sulfur analyzer is a product developed by our company based on decades of research experience in X-ray analysis instruments. It is a main X-ray sulfur analyzer designed for the petroleum industry, which is derived from the company's original DM series calcium-iron analyzers, X-ray sulfur analyzers, and X-ray multi-element analyzers. It is mainly used for measuring the sulfur content in petroleum and its products (and other liquids). It employs energy dispersive X-ray fluorescence (EDXRF) analysis technology, a small X-ray tube as the excitation source, a thin beryllium window filled with a proportional counter tube and secondary filters, and a special optical path system, combined with the hard sample proportional method, enabling the detection limit to reach 10 ppm (300 seconds); it has automatic C/H ratio correction, is suitable for various samples, is integrated, has a large data storage capacity, and can provide results in as fast as 60 seconds. Since its launch in 2005, this sulfur analyzer has sold over 1,000 units and occupies a significant market share.
The 2019 model DM1260 X-ray sulfur analyzer was developed to meet the requirements of the 2019 version of GB/T17040. Besides maintaining the advantages of the original DM1260, the following significant improvements have also been made:
(1) The original proportional counter was replaced with a low-background proportional counter with a thinner window. The distances and angles between the radiation source, the detector, and the sample were adjusted. The high voltage, current, and target material of the X-ray source were also modified.
(2) The original simple multi-channel pulse amplitude analyzer was replaced by a newly designed digital multi-channel pulse amplitude analyzer that employs technologies such as FPGA and DSP. This change reduced the dead time and improved the counting throughput.
(3) Replace the old CPUs such as 80C31 with new large-scale integrated circuit CPUs, and replace the original rack-mounted circuits with surface-mount circuits.
(4) The original black-and-white LCD screen and keyboard have been replaced by a large-screen color touch LCD screen, and the original dot matrix printer has been replaced by a thermal printer.
The improvements in (1) and (2) have reduced the background and enhanced the sensitivity, thereby significantly lowering the detection limit to 2.6 ppm (300 seconds), enabling this sulfur analyzer to fully meet the requirement of PLOQ (combined quantification limit) of 16 ppm in the 2019 version of GB/T17040. At the same time, it complies with the relevant requirements of national standard GB17411 and American standard ASTM D4294. The improvements in (3) and (4) have greatly enhanced the reliability of the sulfur analyzer and improved the user's operation experience.
The launch of the 2019 model DM1260 X-ray sulfur analyzer is the result of our company's pursuit of self-improvement. It will undoubtedly enable our company to maintain a long-term leading position in the domestic X-ray analyzer field.
Characteristics
Fast and accurate - The measurement time is extremely short, usually only taking a few seconds to provide the content result. It also has extremely high reproducibility and repeatability.
Low detection limit - Utilizing EDXRF technology, a low-background thin beryllium window proportional counter tube and secondary filter. Achieving a lower detection limit.
High adaptability - Automatic C/H ratio correction, suitable for various samples. Automatic working curve switching, suitable for wide measurement range.
Long-term stability - Utilizing variable gain digital multi-channel technology, featuring functions such as gain adjustment, ratio correction, and deviation correction, it exhibits excellent long-term stability.
Environmental protection and energy conservation - Radiation protection meets exemption requirements. During analysis, there is no contact or damage to the samples, no pollution occurs, no chemical reagents are needed, and no combustion is required.
Easy to use - touchscreen operation. Samples are directly loaded into the sample cup, and after placing it in the instrument, simply press the [Start] button - truly achieving one-click operation.
High reliability - Integrated design, high degree of integration, strong environmental adaptability, strong anti-interference ability, high reliability.
Data storage - Capable of storing massive amounts of data, it supports data retention even after power loss, and allows for immediate data viewing. Additionally, the stored data can be transmitted to a PC.
High cost-effectiveness - No need for gas, vacuum or dilution. The operating and maintenance costs are extremely low. The price is half that of similar products from abroad.
