12. The following are some commonly used solvents for recovering traces of explosives: Good volatility, but serious fire hazard. Organics Diethyl ether Good volatility Organics Methyl t-butyl ether Available in high purity Good solvent for a wide range of explosives Ethyl acetate Moderate volatility organics Isopropanol Good volatility, but leaves aqueous residue unless dried thoroughly Good solvent for organics, especially nitrocellulose Acetone Poor volatility Organics e.g. nitrate esters, nitroaromatics, nitramines Ethanol Toxic, poor volatility Organic e.g. nitrate esters, nitro aromatics, nitramines Methanol slow to evaporate Inorganic e.g. nitrates, chlorates, per chlorates water Comment Type of explosive Solvent

16. EVIDENCE SAMPLES AT CRIME SCENE LIKELY TO CONTAIN DNA Saliva Edge of toothpicks, depris in toothbrushes Toothpicks, toothbrush 4 Sweat, skin Nose bridge & earlobe Spectacles/glasses 3 Sweat, hair, dandruff Inner lining A cap 2 Sweat, blood & skin Handles and blades of knives Knives, 1 Source of DNA Place where DNA can be found Exhibit S/N
Therefore, if human DNA samples are found at a crime scene, a DNA profiling test can be carried out to determine whether a suspect could be a possible source of a sample. Consequently, DNA evidence has already been put to use to implicate criminals in serious offenses such as; murder case where the victim has suffered multiple stab wounds and a suspect subsequently apprehended in possession of blood stained clothing. The DNA profile from the blood stained clothing could be compared with a sample from the victim. rape case whereby a woman has scratched her assailant and gets skin cells trapped under her fingernails. The DNA profile from the skin cells could be compared with a blood or saliva sample from a suspect. parentage case where a father has disputed his relationship to a child. The DNA profile of child could be compared with a blood or saliva sample from father. mass disaster where victims have lost their recognition in a plane crash. DNA profiles from the remains could be compared with blood or saliva samples from their close relatives.
The DNA scientist has to work with what he receives and the value of his work/ results depends on the quality of the material/sample submitted to him/her This is crucial for so few of us do actually follow sample management procedures when slight mismanagement errors occur and impact the integrity of DNA analytical results. There are several things which the officer investigating a crime, must remember, if the team (investigators and DNA scientists) is to be fully effective;
