Atomic absorption spectroscopy is capable of determining 70 different elements in a sample. Based on the literature values, the cereal box spectrometer proved its value as a decently accurate spectrometer. In conclusion, hydrogen, neon gas is brighter than argon and krypton. Procedures…………………………………………………………………………………………5 The data collected indicated that as the lower the energy of the waves, there was a error percentage. Principle: Raman spectroscopy is based on the use of a laser light to induce oscillation and rotation in human fluids containing glucose. Although many peaks … 7, its can be seen that there is a trend of the longer the wavelength is, the more percent error there is. An equation was then extrapolated from the data that would give the experimental wavelength (expt ? ) Energy must be given up when this occurs, and the energy is lost as light. Instruments like Gas Chromatography, Atomic Absorption Spectroscopy and various. Part 3: Analyzing Spectra.

Fossil energy resources are finite, and thus lack. Lg Marketing Strategy Case Study. Once all the needed chemicals were added we waited for about 70-75mintues for the reaction to take place. to the value given by the manufacturer of the laser. With its electron in a higher energy-level, the atom is now in an unstable, higher energy, excited state. Because the emission of scattered light is influenced by molecular vibration, it is possible to estimate glucose concentration in human fluids [24]. Part 2: Color and Temperature. Spectroscopy Lab Report. Through our cereal box spectrometers, the emission lines of the low energy waves viewed a the color red are more broad than that of the high energy waves because theirs are much longer respectively. Reference……………………………………………………………………………………….....7 Introduction The aims of the lab session was to familiarize with the principles, operation and application of a light spectrophotometer.
