Keep the working area, weighing table and spatula and forceps very clean. Wipe the forceps and spatulas with Kimwipe in-between subsequent samples. Capsules should be folded and crushed into a cube or ball without any protrusions. Samples that are flat or have protrusions tend to get stuck in the sample carousel. Record the final weight after the capsule is sealed. For elemental C and N analysis, the same sample loading procedure should be followed. Also, please ensure that no sample is leaking from the tin.
