Relying on gravity or an insufficiently powered fan to distribute the CA vapor uniformly throughout the chamber will give uneven and erratic results. 3M site has a search feature that will recommend the mask/cartridge needed based upon what you are being exposed to. Superglue fuming, using various systems has also been used for the development of fingerprints in cars10,11 Super Glue really is "super". Iodine fuming has been used since the turn of the 20th century to develop latent fingerprints on porous surfaces, particularly paper.
