Chemical analysis laboratory

Chemical characterisation, food contact, compliance and product safety

  • Perform qualitative and quantitative tests of the organic and inorganic compounds in your paper/board pro-ducts, additives, effluents, black liquors, etc
  • Identify and quantify the presence of chemical contaminants according to the applicable regulatory frameworks
  • Check and verify the quality, safety and compliance of your products according to a specific statutory docu-ment or set of requirements

General informations

The CTP’s Chemical Analysis Laboratory performs tests on various types of samples such as paper/board materials, effluents, additives and black liquors.

The objective is to check that your products or ef-fluents comply with given regulations, client specifi-cations or certification requirements

Our analytical departments also have the requisite expertise to develop testing methods tailored to spe-cific needs, and are active members of various stan-dards commissions

The tests are performed in accordance with the requirements of current regulations and standards (AFNOR, ISO, CEN, TAPPI).



Gas chromatography – mass spectrometry (GC-MS)


The various regulatory frameworks (food contact, product safety, hygiene, etc.) and specifications of your clients make it necessary to investigate a large number of substances, from the percentage level down to trace amounts (filler content, reducible sul-phur content, mineral oils, phthalates, BPA, etc.). The equipment available at the laboratory is capable of meeting all such requirements.

These facilities can also be used to identify the na-ture of unknown substances such as volatile com-pounds or non-intentionally added substances (NIAS) in the framework of a risk assessment.

Our laboratory can assist you in a wide range of areas from characterising a composition to evalua-ting compliance with a statutory document.
