Perfume Analysis By Gas Chromatography

Background: Paper chromatography is one method for testing the purity of compounds and identifying substances. Paper chromatography is a useful technique because it is relatively quick and requires small quantities of material.

Major scientific concepts in this lab include chromatography and pigments. Chromatography is the division of mixtures, solution, and others into its different components. Chromatography is often used to separate a solution into its separate parts. Chromatography filters complicated compounds accurately without involving a difficult process so it is often used. In this lab, we used chromatography to separate the different pigments in the plants. When looking at plants, the colors of the plants are the colors that are reflected from the different wavelengths of the light spectrum. The colors that are not evident are the colors the plants absorb and use as energy. Pigments are the compounds of a plant the enable the reflected colors to be evident. These pigments function to capture light energy from the sun to enable the plants to undergo photosynthesis.

The stationary phase will absorb or slow down different components of the tested solution to different degrees creating layers as the components of the solution are separated. Chromatography was invented by the Russian botanist, Mikhail Tsvet. Chemists use this process to identify unknown substances by separating them into the different molecules that make them up.

Throughout the story “Perfume” by Patrick Suskind, Grenouille is presented as an outsider who is a product of both social and moral decay shown through his birth, description of the setting and description of Grenouille’s characteristics.

1. Paper Chromatography is a method used for the separation of colors which are also referred to as colored chemicals/substances or pigments. This method is used for experiments, to identify coloring agents and to separate out a compound into its various components.

The article Perfume (2006), from the peer reviewed World of Invention says that there are basically fragrances, alcohol and other stabilizers in perfume. However, according to EWG (Environmental Working Group), an analysis of the chemical

Chromatography is a technique used to separate mixtures of substances into their components^2. It can be used to various activities such as separating different pigment of dyes and inks all the way to analyzing DNA sequences.

A measurement of around 0.5 µL, for each compound, was inserted into a gas chromatography in such a way, a syringe holding the compound was pushed down into a column and injection occurred to then start the machine in separating the compound. A computer was right beside it, indicating the graph of multiple peaks and later, after a duration of 4 minutes, a graph was printed out and obtained to then analyze the retention times and percent composition. “The percent composition was found by inserting the following values into the following equation,

In thin-layer chromatography a liquid is pumped across a bed of particles. The liquid that is pumped across is called the mobile phase and the particles are the stationary phase. A mixture of the molecules that will be separated is put into the mobile phase. Thin-layer chromatography tells you/helps you determine the number of compounds in a mixture, the purity of a compound, and the identity of compounds if you have examples to pull information from. Thin-layer chromatography is used to separate nonvolatile mixtures. The dye that was the most polar was the color red and pink which was Rhodamine B and the least polar was the light pink color which was Sudan IV. Our first TLC plate had five

Chromatography is a separation technique in which the mixture to be separated is dissolved in a solvent and the resulting solution, often called the mobile phase, is then passed through or over another material, the stationary phase. The separation of the original mixture depends on how strongly each component is attracted to the stationary phase. Substances that are attracted strongly to the stationary phase will be retarded and not move alone with the mobile phase. Weakly attracted substances will move more rapidly with the mobile phase.

Gattefosse’s goal was to distinguish the medicinal application of essential oils from the perfumery applications.

In this lab, paper chromatography will be used to separate the components of known and unknown mixtures and then used to identify those components. Paper chromatography is a technique where a drop of solution containing a mixture is placed on a piece of filter paper. One end of the filter paper is then placed into a liquid solvent. The mixture will separate into its different components as the solvent moves up the filter paper. The filter paper is known as the stationary phase. The solvent is known as the mobile phase because it uses capillary action to move up the paper. The mixture will be separated into its different components because each component will have a unique chemical affinity for the paper and for the solvent. Theses affinities

There are four different kinds of chromatography, there is gas, paper, liquid, and thin-layer. Gas chromatography is mostly used to determine the chemical composition of the unknown substances. Thin-layer is used on thin plastic or glass trays to identify the composition of pigments and chemicals. Liquid is used to identify an unknown plant pigments and other compounds. Lastly, paper can be used to separate the components of inks and dyes. So in this essay i will talk about two real life cases that involve Gas and paper chromatography and

Perfume, Eau de Parfum, Eau de Toilette, and Eau de Cologne differs on the strength of perfume oils added in the fragrance.
