NSL Analytical, Cleveland, Ohio, USA, has added moisture analysis by Karl Fischer titration to its ISO 17025 accreditation scope. This method measures precise water levels – as low as 10 ppm – in a wide range of organic and inorganic materials, which can be analysed in liquid or solid form by volumetric or coulometric techniques.

NSL can also analyse samples indirectly using oven desorption/vaporisation, the preferred technique for certain types of metal powder samples. These tests conform to the following ASTM standard test methods:

  • ASTM D6304 Water in Petroleum Products, Lubricating Oils and Additives by Coulometric Karl Fischer Titration (including optional oven desorption/vaporisation)
  • ASTM E1064 Water in Organic Liquids by Coulometric Karl Fischer Titration
  • ASTM E203 Water Using Volumetric Karl Fischer Titration

“This technique adds to our market-leading Additive Manufacturing testing services,” stated Ron Wesel, CEO. “The combination of this new instrumentation and the expertise of our chemists means NSL can provide our customers with the most accurate and timely services available.”

Powder Metallurgy: The original net-shape production process

Powder Metallurgy components are relied upon by a wide variety of manufacturing industries, from automotive to power tools, household appliances, chemical engineering, filtration and more.

The main reason for the technology’s success is its cost-effectiveness at producing high volumes of net-shape components, combined with its ability to allow the manufacture of products that, because of the production processes, simply cannot be manufactured by other methods.

To discover more about how the technology has revolutionised component production, browse our Introduction to Powder Metallurgy.
