Methods of Cleanliness Testing

 

3. Gravimetric Analysis of Particle Mass

 

4. Particle Counting and Sizing

 

laboratory balance for gravimetric analysis

The simplest approach to assess the particle quantity is weighing the filter before and after loading the particles onto the membrane. The difference of these values is the particle mass. For basic cleanliness testing, this result is often sufficient.

 

loaded membrane in the particle scanner

Optical high-end scanners allow counting and sizing of particles on a filter within a
few minutes. Since particle scanners work so rapidly and economically, the technique is predestined for daily process control.

5. Particle Measurement in 3D

 

6. Granulometric Analysis with Material Typing

In cleanliness testing, the trend goes towards spatial sizing of contaminant particles. In order to measure the individual size and volume of particles, X-ray microtomography systems are required.

EDX typing of quartz sand

The ultimate solution in particle analysis is sizing and chemical typing by means of automated electron microscopy and EDS. Amongst number and size, the chemical composition for each particle is determined.

2. Gravimetric Analysis of Residual Oil

 

extraction by pressure rinsing

At first, the contaminants are extracted and transferred into a liquid medium by means of rinsing, pressure spraying, ultra sonic rinsing or wiping. Thereafter, the particles are prepared onto a membrane
by vacuum filtration.

extraction of residual oil by means of evaporation

After rinsing, residual oils and grease are separated from the liquid medium (e.g. petroleum ether) by selective evaporation and weighed individually. The residual oil mass is a measure for the quality of greaseless surfaces of components.
