Reference materials
To be able to carry out chemical analyses in a traceable manner, reference materials are often used in calibrating analysis equipment. For many years, VSL has supplied an extensive range of, in particular gaseous, reference materials to users throughout the world. You can find a list of these reference materials elsewhere in these pages. VSL customers include reputable suppliers of specialty gases, environmental laboratories and end users in the energy sector in particular. In addition to gaseous reference materials, we also offer a series of viscosity fluids and standard mineral oil.
