ASTM D4294 X-ray Fluorescence Sulfur-in-Oil Content Analyzer
Summary
SCT-I xry sulfur analyzer 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 of China GB/T 17040, SH/T0742 and
GB/T11140 on repeatability and reproducibility, and it can also
meet requirements of ASTM D4294-02. It provides a measure to
determine sulfur content during petroleum or petrochemical
production process.
I. Purpose
(1) SCI-T sulfur content testing equipment 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. Main technical features
(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) This analyzer 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.
