Performance characteristics

²Analysis method: Total sulfur analysis conforms to ASTM D5453, D6667, D7183; GB17930； SH/T 0689 and other methods; The total nitrogen analysis conforms to methods such as ASTM D4629, D5176, D5762, D6069, D7184, SH/T 0657, etc.

²The total sulfur content of the sample was determined by UV fluorescence method, and the total nitrogen content was determined by chemiluminescence method. Easy to operate, high sensitivity, wide detection range, and accurate results

²Fully automatic constant speed liquid samplerAutomatic control of injection speed, smooth operation, no noise

²UsedAtmospheric balance valve gas sampler technologyTo avoid sample volume deviation caused by different sample pressures and ensure consistency between pressure and volume during each sample injection; At the same time, sample pre gasification technology was adopted to avoid the generation of bubbles in the quantitative tube, which could cause deviation in the injection volume

²UsedRotating boat sampler technologyUsed for solid and viscous samples, avoiding air interference and sulfur component adsorption phenomena; Simultaneously achieving the simultaneous use of liquid sampler and rotary boat sampler without affecting each other, completely solving the problems of injection volume and premature evaporation of light liquid samples

²Adopting a single tube extended membrane dryer avoids the defect of carbon accumulation in multi tube membrane dryers that cannot be cleaned, while also having good drying effect

²A small non adsorption filter has been added to the outlet of the cracking tube, which is easy to replace and avoids carbon deposition causing contamination of the dryer and detector

²The R-type (platinum rhodium alloy) dual head thermocouple temperature sensor is adopted, which greatly increases the operating temperature compared to the traditional K-type thermocouple, prolongs the service life by more than 50 times, and ensures that the detection point and control point are in the same position, ensuring accurate temperature control

²Adopting a fully automatic thermal conductivity mass flow controller, various gas flow rates are completely controlled by computer software, without the need for manual adjustment. Fluctuations in gas source pressure will not cause changes in gas flow rate, ensuring that the flow rate is consistent with the calibration time during each sample measurement and accurate quantification

²The software operation is very convenient, consolidating all the parameters and function keys used in one interface without switching back and forth, including "calibration", "sample analysis" and other operating condition parameters in one interface. At the same time, English/Chinese versions of the operating software can be provided

Power requirements:

Voltage stabilized power supply 230VAC,50 Hz，1600watt

Gas requirements:

Dry oxygen: 0.2MPa, 99.95%，650 mL/min

Dry argon gas: 0.2MPa, 99.99%，200 mL/min

*Moisture content not exceeding5ppm

Environmental requirements

Environmental temperature: A relatively stable room temperature of 25 is required°C±10°C。

Environmental humidity: requires a relatively dry environment, 0-65%RH.

Air quality: Good air quality, corrosive air will quickly corrode components such as solder joints, circuit contacts, and electronic coolers; Dust and dirt are blown into the instrument by the cooling fan and accumulate, which can easily absorb moisture and cause corrosion and short circuits; Dust may also accumulate on the surface of the heat sink, causing poor heat dissipation and damage to the components.
