Monique: Symptoms And Obstacles
Monique,
Unquestionably, the first and most important step in the examination is the microscopic comparison for color and diameter utilizing a comparison microscope. This examination was critical in linking Wayne Williams to the murders he had committed. Another comparison is the dye comparison, although two fibers may seem to be the same color when they are viewed under a microscope, compositional differences could exist. In this method, the visible-light microspectrophotometer is a convenient way for analysts to compare the colors of fibers through special patterns. Lastly, once the microscopic and dye composition phase of the analysis is complete, and before any conclusions can be reached, they must show the same chemical compound. Moreover,

    The point of doing this project is to use paper chromatography to see which dyes are used in the coatings of your favorite colored candies. Chromatography is a technique for separating mixtures. Chromatography can be used to separate specific components from a complex mixture, based on molecular size or other chemical properties. It can also be used to identify chemicals, for example crime scene samples like blood, drugs, or explosive residue. Highly accurate chromatographic methods are used for process monitoring, for example to assure that a pharmaceutical manufacturing process is producing the desired drug compound in pure form.With colored mixtures in paper chromatography, you can see the components separate out on the paper. A mixture of various components enters a chromatography process, and the different components are flushed through the system at different rates.…

    (As The Editors Of Encyclopædia Britannica say “Paper chromatography, technique for separating dissolved chemical substances by taking advantage of their different rates of migration across sheets of paper. The method consists of applying the test solution or sample as a spot near one corner of a sheet of filter paper. The paper is initially impregnated with some suitable solvent to create a stationary liquid phase. An edge of the paper close to the spot is then immersed in another solvent in which the components of the mixture are soluble in varying degrees. The solvent penetrates the paper by capillary action and, in passing over the sample spot, carries along with it the various components of the sample.”) they explain what and how paper chromatography is used for. They all have to do with colors. Having to do with finding the real dyes in colors. (As Science Buddies explain “What color is black ink? Sometimes things are not just what we think they are. Often things can be broken down into component parts. One way to find out it to use a common chemistry technique called chromatography.”) This quote explains that there can be many object in just one object, just like paper chromatography. The paper chromatography experiment it tested to see what kind of dyes are just in one…

    The search for physical evidence at a crime scene must be done thoroughly and followed by the protocol. How the criminalist will decide to execute the crime-scene investigation depends on the size and the locale of the area, as well as on the actions of the suspect(s) and victim(s) at the scene. It must be considered that physical evidence can be anything, from a massive object to a microscopic trace, however, some evidence are clearly visible but others need to be examined in the laboratory in order to be detected. Physical evidence must be processed in a way so as to prevent any change from happening between the time that was collected on the crime scene and the time it is received by the laboratory. When collecting physical evidence from a scene, any criminalist must be aware of the fact that recovery of one type of evidence can destroy another.…
