Chemical analytical testing: When knowledge makes the difference
CTL GmbH is an owner-managed laboratory from Bielefeld where all tests are carried out consistently in Germany.
In a world of growing regulatory demands and rising quality expectations, precise chemical analyses are indispensable. At CTL in Bielefeld you do not just receive measurement results; you receive clarity. Our highly specialised methods help quality managers, product developers and buyers to comply safely with legal requirements such as REACH or CE directives and to strengthen long-term trust in your product.
Our customers rely on state-of-the-art technology. From GC-MS (gas chromatography with mass spectrometry) and HPLC-DAD to ICP-OES, we have high-performance instruments that reliably detect and quantify even the smallest traces of harmful substances.
We go far beyond standard testing. CTL has for years been a point of contact for political institutions, for example in the development of regulations for the tattoo sector. We feed this knowledge directly into your projects. This gives you not only certainty but also valuable time in the market.
