REACH & RoHS analyses, allergens and toxic substances
The entry into force of REACH in 2007 led us to develop our resources and skills in compliance analyses. We have subdivided our analysis range into...+++
It is estimated that 10 to 20% of women and 1-3 % of men suffer from a nickel contact allergy. It is important to highlight that it is not the...+++
Surface tension, surface finish and contamination
The cleanliness of a surface is a key parameter in various industrial processes. It can be characterised by measuring the contact angle of a...+++
Chemical composition of metals and alloys
Failures of mechanical systems are often due to material exchange or to compositions outside specifications. So the check ot the alloy...+++
With two standard packages, we provide analysis of the most commonly requested parameters among those figuring in
Determining the fineness of gold coatings
Among the various quantitative tests performed at Laboratoire Dubois, the determination of the fineness of gold coatingsinvolves some interesting...+++
Tribological tests and lubricant characterisation
In the field of watchmaking and microtechnology, friction consumes a large part of the small energy reserves available. The development of friction...+++
GC-MS thermal desorption-pyrolysis analyses
These techniques supplement the gas chromatography coupled with mass spectrometry analyses (GC-MS), to enable to study all types of organic...+++
