Scope
UV fluorescence sulfur analyzer is
based on UV fluorescence measurement principle and the development of computer
technology combined with a new generation of precision instruments, is
currently the most advanced of the total sulfur content tester, in line with
ASTM D5453, SH / T 0689 and other standards, the instrument is National total
sulfur content of refined oil arbitration standards. Now widely used in the
determination of total sulfur content of crude oil, hydrocarbons and fuel,
petroleum, plastics, petrochemicals, food and so on.
Measurement principle
instrument uses ultraviolet fluorescence method, when the sample is introduced
into the pyrolysis furnace, cracking occurred sample oxidation of sulfide which
quantitatively converted to sulfur dioxide, carried by a carrier gas, off which
the water through a membrane dryer, into the reaction chamber, sulfur dioxide
absorbing ultraviolet light energy into an excited state of sulfur dioxide (SO2
*), the fluorescence emission of sulfur dioxide when SO2 * to return to a
stable state, the energy released by a photomultiplier tube to receive, and
then the micro-current amplifier, computer data processing, the amount of
reaction with sulfur dioxide emission intensity is proportional to the amount
of sulfur dioxide and total sulfur content in the sample is proportional, so
the content of the sample can be determined by measuring total sulfur emission
intensity.
Features
1, computer-controlled operation, enabling
interactive, data, peak shape can be automatically stored print.
2, the operating software can be connected
with LIMIS system, automatic data transmission.
3, the instrument uses the new quartz
pyrolysis tube, the injection volume can be increased to reduce measurement
errors, increase the sensitivity of the instrument, higher repeatability.
4, cooling fans, automatic switch,
eliminating the need to wait for the shutdown to finish samples trouble, saving
time and effort.
5, darkroom system uses the latest
technology, the key components imported detecting element to improve the
detection accuracy and sensitivity of the instrument.
6, equipment imported membrane dryer to
absorb , eliminating the need to frequently replace magnesium perchlorate of
trouble, while reducing the leakage problem.
7, using computer control of temperature,
improve the instrument precision temperature control, and difficult to
over-temperature.
8, using air instead of water cooling,
saving water resources.
9, can be adjusted to take existing
calibration curve calibrated using a standard sample after sample analysis.
