Gravimetry

Photo Gravimétrie

 The cleanliness analysis is given by the difference of weight measured on a dry membrane before and after filtration of the solution used for the extraction of the contamination of the controlled part.


UV and low-angled light

 

Photo_Lumière UV Rasante ENG

The sample to be controlled is illuminated by a low-angled light and UV in a black box permitting the visual detection and localization of particles or traces > 50 µm
Liquid Particle Counting (LPC)

Principe_LPC

The particle contamination of the part to be controlled is extracted with DI water (18 Mohms, filtered at 0,2 µm + ultrasonics, shaking table, …).

A sample of the extracted solution is analyzed with a LPC counting system. The difference between the number of particles from the blank solution and the extracted solution indicates the level of cleanliness of the product.

Granulometry

photo Granulométrie

Gravimetric membranes are scanned and then analyzed by a specific imaging software. This tool is a fast and reliable solution to have the complete cartography of particles and fibers (their number and size) and their properties (size limit > 10 µm).
