Pharmaceutical gases: sensitive helpers for sensitive processes.

As invisible helpers, gases have become indispensable in today's pharmaceutical industry. As a pharmaceutical company, Westfalen fulfils all the regulatory requirements of the German Medicines Act and the corresponding EU regulations. Our Secudur® pharmaceutical line is manufactured exclusively in a GMP-certified plant and is integrated into a tightly meshed control network. This ensures traceability. If required, we can also provide you with batch certificates or test certificates - just as you wish! Learn more about our pharmaceutical gases.

 

Laboratory gases from Westfalen: Highest purities and standards.

Our laboratory gases are used in a wide range of areas - in research and science, medicine and environmental technology, but also in an increasing number of high-tech industrial procedures and processes. Our products are manufactured in our special gases centre in Hörstel, which is geared towards maximum precision. The German Accreditation Body (DAkkS) has accredited our centre to DIN EN ISO 17025 as a calibration laboratory and to DIN EN ISO 17034 as a manufacturer of reference materials: A proof of competence at the highest national and international level! We manufacture standard gas mixtures and individual customer mixtures - with DAkkS calibration certificate and certificate for certified reference materials (CRM) if required.

Ultra-pure gases and gas mixtures from Westfalen: assured quality from our own production.

Where the limits of conventional industrial gases are reached, above-average gas qualities are required. Gases whose minor components are in the ppm (parts-per-million) range. One ppm corresponds to 0.0001 percent by volume. We produce the air gases argon, oxygen and nitrogen in modern air separation plants with purity levels of up to 99.9999 percent by volume. We can also provide hydrogen and helium of the same purity. We fill the latter ourselves from isocontainers, both liquid and gaseous, in our helium filling facility.

Not all gases can be brought to the limit of absolute purity with economically justifiable effort. In addition, there are natural limits due to the chemical-physical properties of some substances. However, our range of ultra-pure gases is always oriented towards the optimum achievable in each case and therefore opens up all possibilities for you!

We produce individual gas mixtures on request, standard gas mixtures are available from stock in our online shop.

Isotopes and isotope mixtures: specialists for analytical and diagnostic procedures.

A special field within high-purity gases and gas mixtures are the stable gaseous isotopes and isotope mixtures. Isotopes are nuclides with the same atomic number but different mass numbers. Almost every naturally occurring element has at least one stable isotope. The remaining nuclides are unstable and decay over time.

Isotopes are used to distinguish between two atoms of the same type.
An atom is replaced by one of its isotopes, which can then be identified in analytical or diagnostic procedures. Procedures of this kind can be found in archaeology (radiocarbon dating) or in the diagnosis of stomach cancer, among other things.

Westfalen produces isotope mixtures gravimetrically, according to your specifications. Different measuring methods are possible.
Isotopes and isotope mixtures are available in Alumini® pressure cans and small bottles as well as in high-pressure containers with a nominal volume of between two and 50 litres.
