Forensic chemists working for Chem Lab Burns, Inc. often work with police to help identify unknown materials found at crime scenes. Many compounds have the same chemical formula, but with different structures. The lab starts with a combustion analysis to help find the formula of the unknown material submitted to the lab. The following is the combustion analysis result for a liquid found at a recent veterinary clinic break-in. Chem Lab Burns, Inc.
