Question one. List at list two main goal(s) of this publication
1).The purpose of the publication is to broaden the information available for the organizations involved in the fight against counterfeit organizations with vibration spectroscopy.
2.) The Second purpose of this publication is providing a model for identifying counterfeit products with genuine products.
Question two. Identify two analytical technique used in this publication and provide the basic theory of this technique.
The first analytical technique used in the journal is Raman spectroscopy. This technique is used in the study of rotational and vibration models in a system. The spectroscopic technique relies on the effect of inelastic scattering and Raman scattering of single wavelength light emitted from a laser in the near infrared, visible and near ultraviolet regions of the magnetic spectrum. This laser light intermingles with vibrations in molecules or other excitations in a molecule resulting in the shifting of energy of laser photons. This shift is the one that gives data about the vibration models in a system (Byrnes 22).
The other analytical technique used in the journal is Near Infra Red Spectroscopy. This analytical technique is used in the identification of molecules by identifying the vibrations in the bonds of a molecule. Each bond in a molecule vibrates at some frequency characteristic of that bond .In a molecule; the vibration of bonds between constituents of a molecule causes a change in the dipole moment of a molecule. A particular molecule will therefore absorb a photon of equal frequency when light is passed through it. Absorption spectra of molecules can therefore be used to determine the chemical constituents of a molecule in terms of the chemical species present in a molecule (Byrnes 26).
Question three. Name three Chemometric techniques used in this report and state what they were used for in this paper.
Multivariate calibration is one of the chemometric techniques used in the journal article. The purpose of this chemometric technique in the journal article experiment is the development of models for the prediction of the properties of pure compounds in relation to counterfeit products. The second chemometric technique used in the paper is cluster analysis. This is a technique that can be used to develop mathematical models for classification of counterfeit and genuine drugs (Byrnes, 45). The third chemometric technique used in the experiment is multivariate stastical process control. This technique is used in the journal article to develop chemometric profiles of counterfeit and genuine drugs.
Question four. Perform further internet search on one of the Chemometric technique and briefly explain in your own words its usefulness in this paper.
Infrared spectroscopy is a very good technique for determining the purity of a compound because it allows the determination of the chemical constituents present in a molecule. Comparison of the absorption spectra of a pure compound and a contaminated compound can help establish whether a compound is genuine or counterfeit (Byrnes 36). Infra red spectroscopy is therefore useful in the identification of counterfeit products hence its use in this journal article.
Question four. Identify a typical data structure used in this publication (hint: number of rows and columns including headings)
This publication has used numerous data structure that include graphs displaying the peaks of various compounds and tables displaying the data used in the analysis of analytical techniques.
