AQF-2100H automaattinen uuni halogeenin ja rikin analysointiin
Combustion Ion Chromatograph with Auto Quick Furnace
The combination of the boat control system and duplex tube combustion guarantees safe and reliable combustion performance without the need for advanced operator training. The combustion process can be completed in as little as five minutes.
Mitsubishi has revolutionized the analysis of halogens and sulfur with the introduction of the AQF-2100H (Auto Quick Furnace), creating a new, fully automated technique termed CIC or “Combustion Ion Chromatography”. Combustion Ion Chromatography is achieved by interfacing an Ion Chromatograph to the AQF-2100H (Auto Quick Furnace) with Mitsubishi’s GA-100 (Gas Adsorption Unit). Now there is available for the first time a fully automated system which can measure and speciate Total Halogens (F, Cl, Br and I) and Sulfur in a single analysis. Mitsubishi has applied its vast knowledge and years of expertise in analytical combustion techniques in developing the Combustion Ion Chromatography method and AQF-2100H. The end result is a powerful, robust, flexible and reliable analytical system applicable to solids, liquids, gases and LPG’s. The AQF-2100H and CIC technique is an ideal alternative to existing cumbersome, dangerous manual methods and techniques. The full automation of ASTM, ISO, DIN, JIS and UOP methodologies is now possible with the AQF-2100H and CIC System.

NSX-5000V rikin / typen / kloorin analysaattori
NSX-5000V series will contribute to the reduction of environmental impact through advanced technologies.It enables automatic, safe and highly sensitive measurement of trace nitrogen, sulfur and chlorine in liquid or gas samples. Can be used in a wide range of applications such as quality control of petroleum/ chemical/ recycled products or automotive fuels and environmental analysis.
Features:
Automatic syringe dilution (ASC-550L)
Automatic dilution can be performed accurately regardless of the
proficiency of the operation by simply setting stock solution and
solvent in the vials. Advance preparation for calibration curves is
no need and waste solution can be reduced, resulting in reducing
environmental load and low running costs
Reanalysis function
After measurement, the “start time of measurement” and “end
time” for chart date can be corrected if necessary to optimize.
Wide range, Easy of use
High/Low, simplified selection of sensitivity for each detector.
Liquid sample temperature control system
By cooling a “vial (containing a highly volatile liquid)” and a
“microsyringe” to low temperature, it is possible to suction stably and inject the sample as a liquid state
Sulfur Measurement
Sample is injected into a heated (800 to 1100 °C) pyrolysis tube
by argon carrier gas. After sulfur compounds in the sample are
pyrolyzed, they are oxidized by O2 gas.
R-S + O2 → SO2 + SO3 + combustion product
The produced SO2 gas is excited by irradiating the ultraviolet ray ν1 (190 to 230 nm). Then, SO2* emits the energy (fluorescent ray) and returns to the ground state.
SO2 + hν1 → SO2* → SO2 + hν2
This fluorescent ultraviolet ray ν2 (300 to 400 nm) is received by the photomultiplier tube and area value is obtained. The sulfur concentration is obtained by a calibration curve preliminarily drawn using standard solution.
Nitrogen measurement
Sample is injected into a high-temperature (900 to 1000 ℃) pyrolysis tube
by argon carrier gas. After nitrogen compounds in the sample are pyrolyzed, it is combusted, oxidized, and converted to nitric oxide (NO). After removing moisture from the combustion gas by a dehumidifier (tube dryer), the following oxidation reaction occurs by the reaction of NO with ozone.
NO + O3 → NO2 + O2 + hν
By this reaction, 590 to 2,500 nm of emitting light is generated. The optical
intensity of this light is proportional to the NO concentration at a wide wavelength range. After emitted light is detected by a photomultiplier tube and signal processing is performed, an area value is obtained. Using the calibration curve, the total nitrogen concentration in the sample is calculated. Some of samples generate interference substances such as SOx and CO2 in the process of oxidative combustion. However, the interference can be decreased to an irrelevant level by the contribution of reduced pressure method.
Chlorine analysis
Samples are combusted in an argon/oxygen atmosphere. The resulting hydrogen chloride is led into a titration cell where it is automatically titrated by silver ions generated by electrolysis. The amount of chlorine is calculated from the quantity of electricity required for the titration.
HCL + Ag → H + AgCl (titration)
Ag → Ag + e (electrolysis)
Sulfur analysis
Samples are combusted in an argon/oxygen atmosphere. The resulting sulfur dioxide is led into a titration cell where it is automatically titration by triiodide ions generated by electrolysis. The amount of sulfur is calculated from the quantity of electricity required for the titration.
SO2 + I3 + H2O → SO3 + 3I + 2H (titration)
3I → I3 + 2e (electrolysis)
