Abstract:
When constructing storage vessels for trace level analysis of gases in the field, aluminum is an attractive material over traditional sample cylinders or air cans made of stainless steel. Not only is aluminum lighter weight than stainless steel which allows for savings when transporting vessels, it is also significantly cheaper due to its abundance and ease of machining. Just like stainless steel, aluminum has the propensity to absorb reactive compounds which can make trace level analysis of compounds such as sulfurs, mercury, ammonia, and VOCs difficult or impossible. Many researchers can overcome these issues with inert coatings for stainless steel components. SilcoNert 2000 (formerly known as Sulfinert) is a well-known, widely used, and openly available from a variety of manufacturers. Due to the catalytic nature of most aluminum surfaces, applying SilcoNert 2000 to aluminum components has yielded less than ideal coatings. Recently, we have developed a new method of applying the coating to aluminum. This presentation will discuss the new technique for application of the coating and resulting data.
