Parameter
Description
Sensitivity / Sample Size
1 µg / 10 g, up to 5–10 times better than similar products, significantly improving accuracy.
Simultaneous Analysis of Sample Size
Available options: 2, 4, or 8 samples; multi-station analysis improves efficiency greatly.
Test Gas Type
Water vapor, organic vapor, and various gases (customized for strong acid gases).
Support for Blank Position Synchronization Test
Supports background subtraction and buoyancy deduction, reducing system errors and enhancing test accuracy.
Vacuum Degassing Temperature Control
Multi-stage temperature programming prevents overheating, protecting samples and avoiding sample loss.
Vacuum Degassing Temperature Range
From room temperature to 400°C.
Full System Anti-Condensation Constant Temperature
Controlled from room temperature to 60°C, preventing condensation throughout the system.
Analysis Test Temperature
Ranging from -180°C to 50°C.
Segmented Pressure Measurement
Equipped with original imported capacitive film pressure sensors, dual sensor configuration. Segmented testing: 0–10 torr and 0–1000 torr. Reading accuracy ≤ 0.15%, offering the highest precision available.
Segmented Pressure Sensor Configuration
Provides higher accuracy for vapor-based adsorbates with low saturated vapor pressure at normal temperatures. Improves test accuracy by more than two orders of magnitude compared to single-pressure sensors.
Vacuum Degree
Less than 0.001 torr; optional molecular pump can reach up to 10â»â¶ torr.
Dual Mode Buoyancy Correction
Mode 1: Buoyancy calculation mode. Mode 2: Background subtraction curve mode.
Steam Concentration Control Range
0.01% to 98% P/Pâ‚€. Uses advanced "static evaporation" method to achieve a wider range of steam partial pressure compared to "carrier gas mixing."
"Humidity/Partial Pressure" Accuracy
Better than 0.001 torr. Direct absolute pressure testing and saturated vapor pressure (Pâ‚€) measurement ensure over 10 times higher accuracy than hygrometers.
Real-Time Saturated Vapor Pressure Test
Measures saturated vapor pressure in real time, ensuring extremely high relative pressure accuracy. Significantly improves accuracy compared to indirect methods like temperature conversion or table lookup.
Steam Trap Cold Trap
Includes a liquid nitrogen cold trap to prevent steam from entering the vacuum pump, protecting the pump oil. Captures high-boiling-point adsorbents, essential for steam adsorption analysis.
Static Adsorption Process
Uses the most advanced vacuum static pure steam adsorption process, eliminating the need for carrier gas and minimizing dynamic gas interference.
Distillation Purification System
Features an advanced automatic distillation purification system that ensures high-purity steam sources, improving test accuracy by reducing reagent purity requirements.
Anti-Condensation Full Temperature Control
All components, including the adsorption chamber, reference chamber, valves, and gas lines, are maintained at constant temperature to eliminate cold spots. Uses high-vacuum air control valves to reduce heating issues and enhance thermal stability.
Intelligent Automatic Calibration
The microbalance automatically calibrates before each test, ensuring consistent accuracy and eliminating manual calibration steps.
Pneumatic System
Features a modular air circuit system with integrated control valves, minimizing leakage points. Uses 316L stainless steel high-vacuum valves, achieving an air leakage rate below 10â»â¸ torr·m³/s. Sealing performance is more than five times better than standard systems, matching high-end imported instruments.
Oil and Corrosion Resistance
All pipelines and valves are sealed with oil-resistant and corrosion-resistant materials. Special valves resist oil and organic vapor corrosion, making the system suitable for water vapor, organic vapor, and petroleum product analysis.
Pipeline Diameter
Larger diameter is essential for achieving high vacuum. Large-diameter valves and pipes at degassing and test positions maximize the ultimate vacuum of the vacuum pump.
Quartz Wire Insulation Seal
Uses advanced quartz wire insulation sealing technology for pressure and temperature sensors, offering low leakage, long-term stability, and resistance to aging.
Intelligent Self-Test
Automatically detects and evaluates the instrument’s airtightness, ensuring reliable operation and performance.
