Organotins: monitor tin pollutants using Chiron AS analytical standards

Organotin compounds, also known as stannans, are organic tin-based chemicals that have historically been used in a wide range of industrial and agricultural applications. They are found in antifouling paints, biocides, plasticisers, pesticides, food packaging and PVC pipes. Yet their intensive use has led to worrying levels of environmental contamination, particularly in aquatic environments.

Some organotins, such as tributyltin (TBT), are now well known for their endocrine disrupting effects on marine fauna. As a result, several of them are now subject to severe restrictions under the European Water Framework Directive.

Reference materials essential for monitoring these persistent pollutants

Faced with these challenges, the detection and quantification of organotins have become absolute priorities for environmental analysis laboratories, public institutions and research players. To guarantee reliable and reproducible results, it is essential to work with certified reference materials.

In response to this problem, Chiron AS (Zeptometrix) now offers the widest range of organotin standards available on the market.

In concrete terms, the Chiron standards are:

• Complies with EPA 8323 and ISO 17353/23161,
• Available as solutions (1000 µg/mL) in suitable matrices (methanol or isooctane), or in pure form (neat),
• Available in a purified version (≥98%) for maximum precision,
• Also available in isotopically labelled (deuterated) standards for robust calibration.

What’s more, this range includes not only single compounds (mono-, di-, tri-, tetra-alkyl or phenyl) but also ready-to-use multicomponent mixtures, particularly suitable for calibration and quality control.

Examples of mixtures available

The most popular references include:

• Standard Mixture 1B, containing six typical compounds in a methanol solution,
• The ISO 17353/23161 OC Mixture, which complies with international standards and includes up to 13 compounds,
• The DOTE/MOTE mixture, ideal for analysis in plastics and packaging materials.

So whatever your protocol or target matrix, you’ll find standards from Chiron AS (Zeptometrix) that are perfectly suited to your needs.

Advantages of Chiron AS standards

• Compatibility with the requirements of environmental regulations and LC-MS/MS or GC-MS techniques.
• Full traceability and certified purity.
