Miniature Bomb Calorimeter for the Determination of Heats of Combustion of Samples of the Order of 50 mg Mass

Abstract

A new bomb calorimeter for the combustion of very small quantities of organic materials has been constructed. The use of a small sample size is particularly important when dealing with explosive materials which when used in larger quantities, may detonate enough to spatter material from the crucible or when using substances which are difficult to prepare and purify in larger amounts. This calorimeter has several unique design features including a light weight bomb, coaxial stirrer, and flame holding sample holder.
