Aluminum capsules are used in place of tin at times when measuring very low levels of carbon as it has a slightly lower carbon blank value. (Use caution, as aluminum does not combust very well.)
Alpha Resources® offers USA-made sample containment options for all major OEM combustion analyzers (LECO®, HORIBA®, ELTRA®, Elementar®, and Bruker®, and more). Our sample containment choices include capsule and boat options in nickel, tin, silver, aluminum, and gel.
