SF 6 is used as a contrast agent for ultrasound imaging. Sulfur hexafluoride microbubbles are administered in solution through injection into a peripheral vein. These microbubbles enhance the visibility of blood vessels to ultrasound.This application has been used to examine the vascularity of tumours. SF 6 plasma is also used in the semiconductor industry as an etchant. 2  SF 6 breaks down in the plasma into sulfur and fluorine, the fluorine plasma performing the etching. 3  The magnesium industry uses large amounts of SF 6 as inert gas to fill casting forms. 4  Pressurizes waveguides in high-power microwave systems.

Fumaric Acid. Excipient (pharmacologically inactive substance) What is it? Fumaric acid (C4H4O4) is an organic acid widely found in nature, and is a component of organic biosynthesis is humans. Chemically, it is an unsaturated dicarboxylic acid. It exists as white or nearly white crystals, odorless with a very tart taste. Fumaric acid is generally nontoxic and nonirritant. Fumaric acid has been used in food and beverage products since the 1940s. Food research shows that fumaric acid can improve quality and reduce the costs of many food and beverage products. It is non-hygroscopic (absorbs no moisture).
