Forensic Chemistry Exam 2
I have been honest and observed no dishonesty.

1. In specific detail, describe a published procedure for the definitive identification of Heroin utilizing gas chromatography-mass spectroscopy (GCMS).

Heroin is a white crystalline powder with no odor and a bitter taste. It is a derivative of morphine in that the –OH (hydroxyl group) is replaced by an acetyl group, -OCOCH3 and has a molecular formula is C21H23NO5 with a molecular weight of 369.42 grams per mole and a melting point of 173°C. Heroin is a schedule I controlled substance meaning it has no medical uses and has a high potential for abuse. Abuse is classified as illegal usage of a drug or excessive use above recommended dosage. Some health effects include nervous system disturbances, narcosis, asthma and acute pulmonary edema. Some symptoms documented are respiratory irritation, meiosis, diplopia, nausea, vomiting, constipation, euphoria, dizziness, sleepiness, coma, respiratory depression, pulmonary edema, death. The central nervous system and the gastrointestinal tract are among the affected systems in the human body. Some lesser known of the above symptoms are defined as such: Narcosis is the state of unconsciousness stemming from drug ingestion. Diplopia refers to double vision.1 Respiratory depression, also known as hypoventilation, is when twelve or less breaths are taken per minute that does not provide the lungs with the proper amount of oxygen. Respiratory irritation refers to any disruption of breathing; an example would be asthma. Pulmonary edema is when the heart is unable to properly pump blood through the body and the lungs become starved for oxygen.

Component Analysis of Illicit Heroin Samples by GC-MS Method was published in Farmacia Vaol LVI, 5 in 2008. The beginning of the article starts on page 577 within Farmacia. Mihaela Gheorghe, Dan BĂLĂLĂU, Mihaela Ilie, Daniela-Luiza Baconi and Anne-Marie Ciobanu performed the procedure.

    Trace evidence is based on Locard's exchange principle which contends that every contact no matter how slight will leave a trace . The trace is normally caused by objects or substances contacting one another, and leaving a small sample on the contact surfaces. Foreign objects or pieces of material present at a crime scene and tracing its origin can assist in an arrest and conviction the same way finding some trace from the victim or crime scene on a suspect can have a strong impact on a case. Trace evidence, though often insufficient on its own to make a case, may support other evidence or even prompt a confession. Because trace evidence can be any number of things, from a paint chip to a piece of glass to plant debris, there are numerous different methods used for analysis. This essay is to only cover the chemistry unit in the analysis of synthetic material, blood and urine samples, to explore how their work helps in the general aspect of crime investigation and how cases are built using this type of trace evidence.…

    (U.S Department of Justice.2013) Field drug testing performed by law enforcement officers are often poorly trained and rely on chemical field tests based on color based indicating positive results or negative results; which can be effect by procedure method, environments, and other influences. (Ryan Gabrielson and Topher Sanders. 2016) Field Tests made by companies like Lynn Peavey, The Safariland Group, and Sirchie often don’t provide information to officers regarding false positives, and as like chemical compounds like the cobalt thiocyanate in Albritton cases can react to up to 80 other compounds, as described as early 1979 by S. H. Johns, A. A. Wist, M. S. ; and A. R. Najam. in Spot Tests: A Color Chart Reference for Forensic Chemists (Johns et al.…

    From the chromatogram/spectrum peak report it is shown that there are two retention times of 15.67 and 9.66. The first peak has 9.66 retention time and has one possible match out of the five which is included in appendix 1.The highest match is ecgonidine, methyl ester (EDME) with 944 match and a 953 reverse match. EDME is a product of the thermal decomposition of cocaine and has been identified as a likely candidate for the detection of concealed cocaine (Analytical Chemistry 1997). The second peak, which has a 15.67 retention time, has also five possible matches, (see appendix 1). From the peak report it can be said that the highest match for the unknown peak is cocaine, as it has the highest match of 934 and a reverse match of 946.…

    In order to identify that a white powder might contain cocaine, a forensic drug chemist can conduct a number of tests. The tests in order to identify cocaine are conducted based on the physical and chemical properties of cocaine. The physical and chemical properties of a substance make it unique, thus identifiable and distinguishable from other physical evidences obtained. One of the physical properties of cocaine is that it is white solid. It may not be identifiable based on its physical properties because they are of generic nature. However, the chemical properties of cocaine may make it easily identifiable among other substances. The chemical property of cocaine is that it is reactive to cobalt thiocyanate and as a result it produces a blue-colored product (Girard, 2007).…

    One of America’s biggest battles today is on narcotics. The most common used narcotics are Vicodin, Percocet, and Oxy-cotton, which are all made with opium. Opium is a reddish-brown heavy scented addictive drug prepared from the juice of the opium poppy, used as a narcotic and in medicine as an analgesic. When opiates are introduced to the brain the body stops producing its own endorphins, which leads to tolerance and addiction. Narcotics cause an initial rush followed by a 4-6 hour high, during the high the user feels relaxed however after these phases wear off the user crashes and produces the desire for more of the drug. If the user doesn’t get more of the drug they go into what is called withdraw. Withdraw happens when the user does not have more of the drug within 8 hours after the user comes down. Symptoms of withdraw are tearing eyes, chills, sweats, nausea and increased heart rate. These symptoms can last 3-4 days if the user doesn’t have more drugs. The severity of withdraw depends on the severity of the addiction.…

    Heroin abuse has been one of the national crisis today, especially with the significant increase of death cases compared to early years. Reviewing the statistics of Drug Enforcement Administration (DEA) back in 2010, it has tripled today with a whopping 10,574 cases. As per the books of Florida Medical Examiners Association in 2014, Heroin as the cause of death actually ranked fourth on the list nationwide. This is indeed a depressing truth and it is terrifying to think of our children’s future if this dilemma continues to happen. This common thought is not new with the Florida lawmakers and they just know that they have to act on it now.…

    Since hair growth is fed by the bloodstream, the ingestion of drugs of abuse is revealed by analyzing a small sample of hair. Hair testing is the most accurate and effective method of finding users of drugs of abuse. Using a small sample of hair cut at the scalp, hair analysis evaluates the amount of drug metabolites embedded inside the hair shaft. It takes approximately 4-5 days from the time of drug use for the affected hair to grow above the scalp. Hair differs from other materials used for toxicological analysis because of its unique ability to serve as a long-term storage of foreign substances with respect to the temporal appearance in blood.…

    For example, if a white powder is submitted for analysis, the primary objective will be to determine its identity. If the powder is suspected of being a controlled substance, the forensic scientist will carry out a series of analyses to identify the powder. However, because each drug has a different set of physical and chemical properties, a different series of analyses is required to identify each drug. As mentioned during our discussion of the scientific method, the forensic scientist must first make an educated guess as to the identity of the substance. Using known drug standards for each type of drug to be analyzed, she must develop and validate a series of analyses prior to analyzing the questioned samples. Consequently, the identification of an uncommon drug can be challenging. Two types of analysis can be used to identify the substance: presumptive and confirmatory. Presumptive analyses look at chemical and physical properties that are not unique enough by themselves for identification but that provide enough information to narrow the search. For example, the forensic scientist may guess that the questioned sample is methamphetamine. A known chemical property of methamphetamine is that it will react with sodium nitroprusside in the presence of sodium bicarbonate and produce a very deep bluecolored product, so the scientist will carry out this test. If the reaction…

    To investigate the practicability of the developed LSV for measuring cocaine concentrations in samples. Six samples were prepared by spiking known concentration of cocaine in water. The concentration and recovery percentage of cocaine in spiked samples were analysed using the standard addition method by LSV and ELISA for comparative study. The obtained recoveries for the spiked cocaine using LSV and ELISA are represented in Table 6. As shown in the table, the detection of cocaine using the developed LSV measurements can be a very reliable detection method for unknown cocaine samples. Six measurements for each sample to assess the reproducibility of the detection, recovery percentage shows a range between ± 2.3 to 9.7 % as illustrated in Table…
