What does the analyzer measure for electrodes?
It provides gas-displacement density and porosity: True (skeletal) density via helium pycnometry Open porosity and pore volume Inputs for volumetric energy density Batch-to-batch consistency
EXPERIENCE THE most advanced Density & Porosity Analyzer
M19 Density/Porosity Analyzer (Helium Pycnometer) for energy — AI-based, ultra-high-precision testing. Standards: ASTM B923-10, ASTM C110-15.
Model: Helium Pycnometer · Industry: Energy
Technology principle
The M19 Density/Porosity Analyzer (helium pycnometer) measures true (skeletal) density and porosity of electrodes and active materials by gas displacement under isothermal conditions. True density and porosity directly govern volumetric energy density, electrode calendering and cell design. Referenced to ASTM B923 and C110, the analyzer gives battery and electrode developers reliable, traceable density data to optimize active-material selection and electrode engineering.
Applications
- Cathode and anode active materials
- Calendered electrode coatings
- Graphite and silicon anodes
- Solid-electrolyte powders
- Conductive additives
- Porous electrode structures
Key capabilities
- Lightweight, compact and ergonomically engineered, the M19 Density/Porosity Analyzer (Helium Pycnometer) pairs a 15" capacitive touchscreen with enhanced pressure- and flow-control hardware, so operators run a full energy test sequence with minimal training and markedly shorter cycle times. Available in aluminum or stainless-steel variants, it ships with real-time remote support, USB connectivity and remote-control automation. Domestic manufacturing in India and the USA keeps maintenance cost and downtime low, and a 2-year extended warranty is available.

Frequently asked questions
How does it outperform liquid methods?
Helium accesses fine open pores without wetting or contaminating sensitive active materials, giving faster, more accurate true density with no hazardous reagents.
How does the gas-expansion method improve accuracy?
The isothermal approach: Measures true sample volume precisely Compensates for temperature and pressure drift Averages multiple cycles automatically Self-calibrates for zero drift
What are the advantages of domestic manufacturing?
Local build delivers: Faster service and local support Reduced lead time and spare-parts availability Lower import cost and easy customisation 2-year warranty with on-site support
Can it integrate into energy workflows?
Yes — secure records, connectivity and PDF/CSV export let density data feed electrode development and QC.
How does it support standards compliance?
Traceability to ASTM B923 / C110 plus tamper-proof records keeps density data audit-ready for QA.
