KEY FEATURES

Module Design for Minimal Dead Volume
The internal gas path design of the instrument adopts a unique integrated metal module design, which not only reduces the internal dead volume spacebut also helps mitigate possible leaks.
Saturated Vapor Pressure P₀
An independent P₀ pressure transducer is configured at 133 kPa for P₀ value testing,enabling real-time P/P₀ measurement for more accurate and reliable test data. Alternatively, an atmospheric pressure input method can be used to determine P₀.
Independent analysis ports
With independent analysis ports, the system employs a unique vacuum control logic that allows each station to operate without disruption, even when using a single mechanical pump or pump group. This enables simultaneous, independent experiments, meeting diverse adsorbent testing needs while ensuring high efficiency.
Thermal Stabilization
A core rod in the sample tube reduces deadvolume and stabilizes the cold free space coefficient, while an iso-thermal jacket maintains a constant thermal profile along the tube. Additionally, automatic helium correction ensures precise calibration for any powder or particulate material, minimizing temperature-related deviations during analysis.

High Accuracy Pressure Transducers
Equipped with 1000 torr pressure transducers, the Meso Series enables precise physical adsorption analysis, achieving a partial pressure (P/P₀) as low as 10^-2 for nitrogen (N₂) at 77 K.
Optimized Manifold Contamination Control
This system features a multi-channel, adjustable, and parallel vacuum design with segmented vacuum control. This setup effectively prevents samples from being drawn up into the analyzer therefore preventing manifold contamination.
Liquid Nitrogen Dewar
The use of 1 L Dewar flasks in conjunction with a sealed cover ensures a stable thermal profile along the entire length of both the sample tubes and P₀ tubes throughout the testing process.
Sample Preparation
Equipped with four in-situ degassing ports, enabling simultaneous degassing and analysis. Each port offers independent temperature control from ambient to 400°C, ensuring precise sample preparation.

SOFTWARE

PAS Software is an intelligent solution for operation control, data acquisition, calculation, analysis, and report generation on the Windows platform. It communicates with the host via the LAN port and can remotely control multiple instruments simultaneously.

PAS Software adopts a unique intake control method, optimizing pressure in the adsorption and desorption processes through a six-stage setting, which improves testing efficiency.
Changes in pressure and temperature inside the manifold can be directly observed in the test interface, providing convenience for sample testing and instrument maintenance. The current state of analyzer can be intuitively understood with the indicator light and event bar.

Each adsorption equilibrium process is dynamically displayed on the test interface. Adsorption characteristics of the sample can be easily understood.

External sample preparation device with four-degas stations can remove adsorbed contaminants from surface and pores of samples with heating in flowing gas/vacuum. Temperature can be set and controlled from ambient to 400 ºC.

Low Form Dewar flask
Long lasting, high volume (1 L) Dewar flasks assure a constant thermal profile along the length of sample tubes during experiment.
Fast, Sensitive Testing
Adsorption peak looks sharp, no trailing phenomenon, the change of nitrogen concentration caused by each sample adsorption is not diluted at all; the sensitivity of the sample test is greatly improved. The test efficiency is greatly improved under the condition of sufficient adsorption and the comparative test of four samples in one time only needs about 15 minutes.

SOFTWARE

The AMI-Surface DX software provides intuitive operation with real-time visualization of nitrogen and helium flow. During analysis, users can monitor adsorption activity dynamically, offering a clear understanding of test progress and conditions. Ideal for both novice and advanced users, the interface ensures reliable, traceable operation.

INTRODUCTION

True density is a critical physical property for solid materials—especially powders—affecting everything from product performance to quality control. True density reflects a material’s purity and structural compactness, both of which play a direct role in its end-use properties.
Traditionally, density has been measured using Archimedes' water displacement method. However, this approach suffers from manual error, liquid drainage issues, and poor repeatability. In response, the International Organization for Standardization (ISO) adopted the gas displacement method (ISO 12154) as the official standard for true density measurement in 2014.
The Densi 100 True Density Analyzer quickly and accurately determines the true volume and true density of a wide range of solid materials, including powders, granules, and solid blocks. With a sample chamber volume range of 1 cm³ to 100 cm³, the system accommodates both small and large samples. Each analysis is completed in approximately 3 minutes, delivering reliable results without compromising accuracy.
√ TEST GAS: Helium or Nitrogen
√ Characteristic: Non-Destructive
√ Resolution: 0.0001 g/ml
√ Repeatability: +/- 1%
