Assay of organotin compounds

The analysis of organotin compounds (such as tributyltin (TBT), triphenyltin (TPhT), or dibutyltin (DBT)) allows for the detection of these organometallic pollutants historically used in antifouling paints, PVC stabilizers, and certain plasticizers. These persistent and toxic substances are now strictly regulated due to their impact on the aquatic environment and human health.

The analysis aims to verify the regulatory compliance of finished products, materials and industrial discharges, in accordance with the requirements of REACH, RoHS regulations and European environmental directives.

Analytical methods: GC-MS for specific and sensitive detection

Gas chromatography-mass spectrometry (GC-MS) is the reference method for the determination of organotins .
It allows the separation, identification and precise quantification of the different tin derivatives in complex matrices after a derivatization step.

The targeted compounds include, but are not limited to:

• Tributyltin (TBT)
• Triphenyltin (TPhT)
• Dibutyltin (DBT)
• Monobutyltin (MBT)
• Trioctylétain (TOT)

The analysis is carried out at trace levels (µg/kg) to meet environmental monitoring, product compliance and material safety requirements.

Applications and regulatory challenges

Organotin analysis is relevant to several industrial and environmental sectors:

• Environment : control of contamination in sediments , marine waters and industrial effluents .
• Materials and packaging : verification of the absence of organotins in polymers, flexible plastics and coatings REACH and RoHS regulations .
• Cosmetics and hygiene : compliance of formulations and packaging with regard to restrictions on heavy metals and organotin compounds.
• Marine paints and coatings : control of antifouling products to prevent biotic and aquatic contamination.

This service can be combined with heavy metal analysis (ICP-MS) or organic plasticizer testing for a complete assessment of the chemical conformity of materials .

Affected matrices

YesWeLab's partner laboratories perform organotin assays on:

• Surface water, sediments, mud, soils
• Paints, varnishes and coatings
• Polymers, PVC, packaging and plastic materials
• Cosmetics and industrial chemicals

Each method is adapted according to the matrix , the required detection levels and the applicable normative references .
