GD-17040 Automatic X-ray Fluorescence Sulfur Analyzer for trace sulfur analysis refer to ASTM D4294, ISO 20847 and ISO 8754
Test Method:
The benchtop XRF Analyzer for the analysis of sulfur in fuels according to the latest test methods: ASTM D4294, ISO 20847 ISO 8754, IP496, IP336, and JIS K2541-4. The results of the repeatability test for sulfur are well within the limits set by ASTM D4294, being the most stringent method.
Test Significance:
The sulfur content of fuels is widely regulated to reduce atmospheric emissions of sulfur dioxide, or SO2, and other sulfur oxides, or SOx, during combustion of the fuel. Sulfur dioxide has wideranging negative health effects, particularly impacting the respiratory system as well as contributing to the formation of acid rain. The primary sources of SO2 in the atmosphere are from sulfur contained in fossil fuels that are burned for power generation and transportation as well as naturally-occurring volcanic emissions. To limit SO2 discharge into the atmosphere, various organizations and governments have imposed increasingly strict limits on the sulfur content of fuels. A recent example of this is the International Maritime Organization's (IMO) regulation set to take place in 2020 limiting the content of sulfur in marine fuel at 0.5%, reduced from the current 3.5% limit.
I. Application
1. Total sulfur analysis from ultra low sulfur fuels to crudes.
2. For use in refinery labs, pipeline terminals, additive plants and inspection laboratories.
3. Complies with ASTM D4294, ISO 8754, ISO 20847.
II. Key Features
(1) With electrical, mechanical and microprocessor integration design, so it is compact and beautiful;
(2) The Automatic X-ray Fluorescence Sulfur Analyzer can determine various products and in a wide measurement range. It is rapid for analysis and it only need little standard sample.
(3) Adopts fluorescence intensity ratio analysis methods, it can make correction to temperature and pressure automatically and it can also make correction to ratio of carbon and hydrogen (C/H).
(4) Large LCD for display; Man-machine conversation system; Sound alarm for operation mistake;
(5) It has self-diagnostic function, so it can determine its working state and electric parameters by making counting measurement and energy spectrum measurement using reference samples.
(6) Equipped with a RS232 serial port, it can connect with any computer or web system.
(7) The ISO 8754 Low Sulfur Analyzer takes disposable sample cell with Mylar film, so it can avoid cross contamination. Sample cell is made by a multifunctional pressure shaping device, so it is rapid and convenient. There is a hole on the sample cell cover and you can record sample serial number, S% (m/m), and date on the sample cell cover.
(8) The sample holder is installed on a slide rail, so it can move out and move in automatically. It can move out from inside of the instrument for sample location and anti-leakage parts replacement. It is convenient and it can avoid any contamination to detection system.
(9) The ISO 8754 Low Sulfur Analyzer can save large quantity of test data. You can browse test data and calibration curves at any time.
(10) It uses a thermal printer, so it is easy to replace printing paper.
(11) Tightly protection measures to avoid oil leakage. The sample cell is placed on the leakage protection device. The sample cell can enter into the detection system together with the leakage protection device only during sample analysis procedures. If the instrument is not at sample analysis state, the leakage protection device will move out, so this can avoid any contamination to the detection system.
(12) Its safe X-ray protection measures can keep people from injury of X-ray radiation.
