LS-17040 X-ray Fluorescence Sulfur Analyzer
Model No.: LS-17040
I. Summary and purpose
1. Summary
Environment pollution is attracting more and more governments and
public concern. The cry for ecological environment and atmospheric
environment protection is increasingly louder. The key culprit to
atmospheric destruction and pollution is discharge of CO2 and SO2,
which are from combustion of power fuels. Lowering down the sulfur
content in the gasoline, diesel oil, heavy oils used in vehicles,
ships, and airplanes will highly reduce pollution to atmosphere.
Europe and our government have promulgated a series of standards on
sulfur content of petroleum products to restrict its production and
discharge. SO2 may also cause catalyst poisoning in petrochemical
industry and form acid rain in the atmosphere.
The instrument is specially designed to determine sulfur content
in the petroleum products. Adopts energy-dispersive principle, and
with electrical, mechanical and microprocessor integration design,
so it is rapid and accurate. It can meet the requirements of
national standard GB/T 17040,SH/T0742 and GB/T11140 on
repeatability and reproducibility, and it can also meet
requirements of ASTM D4294-03 on these indexes. It provides a
measure to determine sulfur content during petroleum or
petrochemical production process.
2. Purpose
(1) It can be used to determine mass% of total sulfur in the
crude petroleum, petroleum, heavy oil, diesel oil, gasoline, and
naphtha.
(2) It can be used to determine total sulfur content in the
products of coal chemical industry, such as primary benzene.
(3) It can be used to determine total sulfur or sulfide in other
liquid or solid powder samples.
II. Technical specifications and parameters.
1. Instrument characteristics
(1) With electrical, mechanical and microprocessor integration
design, so it is compact and beautiful;
(2) It 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) It 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) It 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.
