PARTICLE ANALYSIS Technical cleanliness

Assessing component cleanliness

Measurable results.
Traceable analyses.

Our laboratory performs particle contamination determinations and analyses on functionally relevant components. We analyse parts up to 2 m long and 1 m wide. Our work supports customers in medical technology, automotive and supply industries, hydraulics, precision engineering and other sectors.

Using equipment developed in-house, many years of experience and trained personnel, we deliver results tailored to your requirements. We also carefully consider the room environment and continuously monitor system cleanliness using blank values.

Extraction in our own laboratory

The right method
for your test object.

We perform the common extraction methods in-house. The cleanliness of our equipment is continuously monitored using blank values.

01

Spraying

Targeted rinsing of the surfaces under investigation.

02

Rinsing

Extraction by controlled rinsing of the component.

03

Ultrasonic

Removing adhering particles using ultrasonic extraction.

04

Shaking

Agitated extraction for suitable test objects and requirements.

Analysis of test filters

Mass, count
and particle size.

Depending on the application, we determine the total mass of contamination and assess particle coverage on the analysis filter.

01 / GRAVIMETRY

Total particle mass

For gravimetric analysis, we use a Kern analytical balance with an accuracy of 0.01 mg and automatic calibration.

Gravimetry determines the total mass of the particles, but not their size distribution on the analysis filter. For precise weighing, the filter is carefully prepared, dried in an oven and cooled in a desiccator.

02 / LIGHT MICROSCOPY

Counting and measuring particles

Light microscopy (LM) and scanning electron microscopy (SEM) can be used to examine, count and measure particles deposited on the analysis filter.

Our computer-controlled Jomesa system automatically counts and measures particles and distinguishes between metallic and non-metallic particles, delivering precise and repeatable results.

03 / PARTICLE SIZE DISTRIBUTION

The entire filter in view

The evaluation determines the number and size of detected particles across the analysis filter. Since even a single critical particle can affect a component's function, the entire filter area must be counted. Brändle GmbH works with specialised institutes for scanning electron microscopy.
