Gravimetry Analysis

Mass-Based Contamination Evaluation for Technical Cleanliness

Gravimetry Analysis measures the total mass of contamination collected on a membrane filter. In Indian industry, this result is commonly referred to as the 'Millipore Value', although gravimetry is the correct technical term.

Why Gravimetry Matters

Gravimetry measures contamination mass on the membrane filter and helps determine whether further particle analysis is needed.

What is Gravimetry?

Gravimetry determines the total contamination mass collected on a membrane filter after extraction.

Why is Gravimetry Important?

Gravimetry records the total extracted contamination mass before detailed particle analysis and is required by many Technical Cleanliness specifications.

When is Particle Analysis Required?

Gravimetry indicates the quantity of contamination, while particle analysis identifies particle size, count and composition where required.
