Chapter 5 – Forensic Toxicology 1. What are the three areas covered by forensic toxicology? Toxicology covers post-mortem drug testing‚ workplace drug testing and investigations into contraband materials. 2. Name six specimen types that are often tested in forensic toxicology. Under what circumstances is each specimen preferred? Blood – When testing for DUI’s‚ and two samples for every death case. Urine – Preemployment drug testing and is preferred over blood as its eacsy to collect large amounts

PHY 114: Absorption of Nuclear Radiation Abstract: The purpose of this experiment was to determine the mass thickness attenuation factor for beta rays when they pass through polyethylene sheets of varying thicknesses. This was done by using an apparatus that measured the seven different intensities and then taking these values‚ putting them through a number of calculations and finally generating a graph of ln(I_corr) versus the thickness of the polyethylene sheets. Once this graph

Determining Red 40 Concentrations Using Absorption with Beer’s Law Introduction I like color and enjoyed learning about wavelengths and the spectrum of light‚ so I considered incorporating something related to that into my Internal Assessment. We also had just used concentrations in our Group 4 Project‚ so when I found an experiment that dealt with both of these I thought it was a great idea. This experiment is not completely original; the basic concept has been used multiple times. It uses Beer’s

The goal of this experiment was to measure spectroscope position to calculate wavelengths of line emission spectra while also using this data to determine the unknown mixture of the flame emission procedure of the experiment. The original hypothesis was that the spectroscope would show multiple different line emission spectra in which the ΔE would be negative there was an emission of light as the electron’s decreased in electron transitions. This hypothesis was proven correct‚ as well as‚ the unknown

3.5.3 X-Ray Diffractometery (XRD). The crystallinities of pure Zolmitriptan‚ excipients and liquisolid system were evaluated by XRD measurement. It has been seen that polymorphic changes of the drug are important factors‚ which may affect the drug dissolution rate and bioavailability(135). The X- ray diffractogram of pure Zolmitriptan Figure (25) exhibited several sharp peaks at different angle (2Ɵ)‚the three strongest angles were 19.2 Ɵ‚ 21.9 Ɵ and 23.8 Ɵ ‚other angles were 12.2 Ɵ‚13.7 Ɵ‚ 14.2

ACKNOWLEDGEMENTS It is usually said that no man is an island unto himself‚ and any man who so lives all by himself‚ without interacting with his fellow men is in the words of Aristotle‚ “either a beast or a god”. Mutual co-operation and interaction form the cardinal feature of human life. The task of writing this report has not‚ in the least‚ been an easy one‚ and it would be axiomatic to add that all the numerous tasks involved could not be have been accomplished successfully singly

Experiment A Spectroscopic determination of Iron with Phenanthroline Unknown # 2 Mass of Mohr’s Salt: 0.2040 1. 5mL of 6M acetic acid was measured and transferred into a 100mL volumetric flask with a pipette and diluted to the mark. Concentration = [0.2040(±0.0001)g/100(±0.08)mL]*[(1mol/392.16g)/(1L/1000mL)] = 0.005202(±0.09382%) = 0.005202(±0.000005)mol/L 2. 10mL of the above stock solution was transferred to a 250 mL volumetric flask and diluted to the mark.
