DM8000 Multi-element test analyzer
Description:
The DM8000 multi-element analyzer (dispersive type) is an
analytical instrument that has been developed by our company based
on decades of research experience in X-ray fluorescence analysis.
It is a product that has reached the international advanced level
and is derived from the company's original DM series X-ray
fluorescence calcium-iron analyzer, sulfur analyzer,
aluminum-silicon analyzer, and multi-element analyzer. It adopts
the simultaneous (or multi-channel) wavelength dispersive X-ray
fluorescence (WDXRF) analysis technology, allowing all channels to
simultaneously measure any ten elements ranging from Na to U. For
most elements, its measurement range can be as low as ppm and as
high as 100%. It features fast analysis speed, high accuracy, low
human error, low operator labor intensity, only requiring a
one-time investment, and no pollution. Therefore, it is widely used
in various industries such as building materials, metallurgy,
petroleum, chemical industry, geology, mining, etc.
The key components of the DM8000 multi-element analyzer (dispersive
type) adopt imported products. For instance, the X-ray tube uses a
400W thin beryllium window X-ray tube produced by Varian Company,
and the detectors for light elements such as Na and Mg use 0.6μm
ultra-thin polyester windows produced by Moxtek Company. The
temperature control accuracy of the constant temperature chamber is
less than 0.1℃, the gas flow system uses a high-precision gas flow
density stabilization device, and the pressure stability is less
than 3Pa. It also has a sample spin device to eliminate measurement
errors caused by sample non-uniformity. Thus, this analyzer has
extremely high precision and accuracy, reaching the international
advanced level. The excellent design of the shielding protection of
this analyzer ensures no radiation leakage and meets the radiation
exemption requirements.
The DM8000 multi-element analyzer (dispersive type) has
particularly demonstrated its superiority when applied in China's
cement industry. This is because this instrument was originally
developed specifically for the cement industry, and it complies
with the relevant requirements of the national standard GB/T
176—2017 "Chemical Analysis Methods for Cement", the industry
standard JC/T1085—2008 "X-ray Fluorescence Analyzer for Cement",
and the industry standard JB/T11145—2011 "X-ray Fluorescence
Spectrometer". Its performance is better than that of imported
similar products for the cement industry, while the price is only
half of that of imported similar products, offering an unparalleled
price-performance ratio. Additionally, the convenience of
after-sales service provided by domestic enterprises is
incomparable to that of foreign enterprises.
Application
It is mainly used for measuring the concentrations of Na2O, MgO,
Al2O3, SiO2, SO3, TiO2, K2O, CaO, Fe2O3, etc. in materials such as
cement raw materials, clinker, cement and others. It can be used
independently or in conjunction with other equipment to provide
detection signals for the automatic control system of raw material
batching in the cement production process, forming an "analyzer -
microcomputer - belt scale" automatic control system.
In addition to the cement industry, it can also be used for the
concentration analysis of Na2O, MgO, Al2O3, SiO2, SO3, TiO2, K2O,
CaO, Fe2O3, etc. in solid, liquid and powder samples from
industrial and mining departments such as power plants, brick and
tile factories, metallurgy, petroleum, geological and mining
industries.
Characteristics
Quick simultaneous - Simultaneous mode (or multi-channel mode),
where the elements to be measured are analyzed simultaneously at
high speed. Generally, the concentration results are available
within a few minutes.
High accuracy - The wavelength dispersive XRF analysis technology
boasts an extremely high resolution that surpasses that of energy
dispersive analysis, enabling accurate measurement of adjacent
light elements.
Easy to use - For sample grinding, pressing into tablets or
melting, simply put the sample into the instrument and press the
[Start] button. It truly enables one-click operation.
Long-term stability - equipped with constant temperature chambers,
stable gas flow density, sample spin devices, and variable gain
digital multi-channel, with excellent long-term stability.
High reliability - The fixed path design ensures that the
instrument has very few moving parts, and it is highly integrated
with strong environmental adaptability, resulting in high
reliability.
The software is powerful - it has various functions such as ratio
or matrix effect correction, deviation correction, statistical
calculation of qualification rates, error prompts, etc. It is also
available for free.
Update to the latest version and add software functions according
to user requirements.
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.
High cost-effectiveness - No need for water cooling, and the
operating and maintenance costs are extremely low. The price is
half that of similar products abroad, and it is suitable for the
national conditions of our country.
