The Measurement of Pharmaceutical Lubricants Using the TriStar II Krypton Option

A major advantage for using the TriStar II with the Krypton Option is the ability to measure low surface areas. Although the TriStar II standard nitrogen system can measure surface areas as low as 0.01 m2 /g, the Krypton Option enables you to measure areas as low as 0.001 m2 /g and provides increased accuracy for materials under 1.0 m2 /g. Krypton is also useful for analyzing materials that are difficult to sample or have very low density; pharmaceutical lubricants, for example.
