Porous or irregular sample volume and specific surface area tester

1、 Working principle:

Using high-purity nitrogen/helium as the medium, the absolute volume of the sample is calculated with an accuracy of ± 0.01% through precision pressure sensors and gas expansion algorithms.

Triple safety protection: anti-static design, gas circulation and voltage stabilization system, non-destructive testing, ensuring zero risk of high-risk sample testing.

Adaptability: Can be connected to an external high-pressure container to directly measure the volume change of the sample inside the sealed container (application: expansion rate of propellant in high-pressure environment).

2、 Significant features:

1）absolutely safe

Fully inert gas environment, completely eliminating the risk of water explosion/chemical reaction of energetic materials, in compliance with GJB 5891 explosion-proof certification standard. Explosion proof cabin design, capable of withstanding internal combustion and explosion impacts.

2）Ultra wide application scenarios

Energy containing materials: particle volume density, propellant porosity, moisture absorption analysis.

High pressure closed system: monitoring of solid loading rate in rocket fuel tanks and tracking of catalyst volume changes in high-pressure reactors.

Porous/hygroscopic materials: Determination of pore volume of activated carbon, compacted density of lithium battery electrode materials, and reference volume of pharmaceutical effervescent tablets before contact with water.

3）Research grade accuracy

The volume resolution reaches 0.001 mL, supporting full scale coverage from microgram level samples (such as nano energetic materials) to kilogram level industrial batches (such as energetic material compression charge columns).

4）Intelligent operation

One click start adaptive mode: automatically matches sample types (powder/porous/dense) and optimizes test parameters.

3D dynamic volume modeling+AI data correction enables accurate analysis even for complex internal cavity samples such as honeycomb catalysts.

4、 Application Fields

Energy materials: compaction density of lithium battery negative electrode materials, porosity control of nuclear fuel pellets

Chemical safety: Verification of volume stability before transportation of explosive chemicals, prediction of porous catalyst activity

Frontier research: Calculation of specific surface area of metal organic framework materials (MOFs), analysis of structural integrity of 3D printed energetic devices

Industrial quality inspection: monitoring of solid packing in high-pressure reactors, screening for batch consistency of energetic raw materials

National Defense and Aerospace: Uniformity Testing of Solid Rocket Propellant Charge Density and Evaluation of Ammunition Storage Status

Why do we have to choose EnerVol-50？

The fatal flaw of traditional methods:

Drainage method: Energy containing materials are prone to combustion/explosion when exposed to water, and porous materials absorb water, resulting in severe distortion of volume data.

Geometric measurement method: cannot handle irregularly shaped internal pores, let alone adapt to high-pressure sealed container scenarios.

Conventional gas method: Lack of explosion-proof design, high risk of gas leakage during high-pressure testing, and severe data drift.
