Parameter
Sensitivity / Sample Size
1 µg / 10 g, 5–10 times better than similar products, significantly improving accuracy.
Simultaneous Analysis of Sample Size
Options: 2, 4, or 8 samples; multi-station analysis improves efficiency greatly.
Test Gas Type
Water vapor, organic vapors, and various gases (customized for strong acid gases).
Support for Blank Position Synchronization Test
Allows background subtraction and buoyancy correction to eliminate system errors and improve test accuracy.
Vacuum Degassing Temperature Control
Multi-stage temperature programming prevents overheating, protects samples, and avoids sample loss.
Vacuum Degassing Temperature Range
From room temperature up to 400°C.
Full System Anti-Condensation Constant Temperature
Controlled from room temperature to 60°C, ensuring no condensation occurs during testing.
Analysis Test Temperature
Ranging from -180°C to 50°C, suitable for a wide range of experimental conditions.
Sectional Pressure Measurement
Equipped with imported capacitive film pressure sensors, dual sensor configuration. Segmented pressure ranges: 0–10 torr and 0–1000 torr. Reading accuracy ≤ 0.15%, the highest precision available.
Segmented Pressure Sensor Configuration
Provides higher accuracy for vapor adsorbates with low saturated vapor pressure at normal temperatures, improving test accuracy by over two orders of magnitude compared to single-sensor systems.
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 2: Background subtraction curve method.
Steam Concentration Control Range
0.01% to 98% P/Pâ‚€. Utilizes advanced "static evaporation" method for steam generation, enabling a wider range of partial pressures compared to "carrier gas mixing."
"Humidity / Partial Pressure" Accuracy
Better than 0.001 torr. Direct absolute pressure testing and measurement of saturated vapor pressure Pâ‚€ ensure more than 10 times better accuracy than hygrometers.
Real-Time Saturated Vapor Pressure Test
Enables extremely high relative pressure accuracy by directly measuring Pâ‚€, avoiding indirect methods like temperature conversion or lookup tables.
Steam Trap Cold Trap
Includes a liquid nitrogen cold trap to prevent steam from entering the vacuum pump, protecting the pump oil and capturing 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 reducing dynamic interference.
Distillation Purification System
Features an automatic distillation purification system that ensures high-purity steam sources, improving testing accuracy and reducing reagent purity requirements.
Anti-Condensation Full Temperature Control
All gas paths, valves, and chambers are kept at constant temperature (from room temperature to 60°C), preventing cold spots and enhancing thermal stability.
Intelligent Automatic Calibration
The microbalance automatically calibrates before each test, ensuring accuracy and eliminating manual calibration tasks.
Pneumatic System
Uses a modular air circuit system with integrated control valves, minimizing leakage points. High-vacuum 316L stainless steel valves reduce system leakage to below 10â»â¸ torr·m³/s, improving sealing performance fivefold.
Oil and Corrosion Resistant
All pipelines and valves are sealed for oil and corrosion resistance, making it 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 level.
Quartz Wire Insulation Seal
Sensors such as pressure and temperature use quartz wire insulation technology, offering low leakage, anti-aging properties, and strong stability.
Intelligent Self-Test
Automatically detects and judges the airtightness of the instrument, ensuring reliable operation.
Automatic Email Notification
Send automatic emails to the operator's mobile phone when tests are completed or unexpected events occur, allowing real-time monitoring even when away from the lab.
Other Parameters
Clear graphical interface for all hardware control operations. Detailed logs accurate to the second for reliable post-sales support. Live voice prompts for each step. Multi-language modules available for customization. Global procurement with all key components imported.
Instrument Dimensions
Height: 110 cm, Width: 100 cm, Length: 70 cm. Weight: 200 kg.
