For over 40 years, Butterworth Laboratories has provided independent, contract analytical services to the global pharmaceutical and related industries.
Almost any mixture of compounds can at least be separated using either Thin-Layer Chromatography (TLC) or Paper Chromatography. These techniques are used to identify compounds such as sugars and antibiotics and can even determine impurities and related substances down to ~0.5%.
We maintain our capability to perform these classical non-instrumental analyses, even though, in many cases, they have been largely surpassed by instrumental applications.
The latest technology combined with our expert team of scientists make us leaders in Quality Control Testing, Method Development, Method Validation and Stability Testing of both pharmaceutical raw materials and finished products.
We refine this service by promoting a culture of open communication between our analysts and our clients, ensuring that you retain control of your work.
