Mass spec is use to further confirm your sample analyzed. Mass spectroscopy breaks down the sample into its components. It does this by bombarding the molecule with some type of particle (either alpha or beta... or i may be way off). This will break down the sample into certain weights. The mass spec will tells you these molecular wieghts. On your software that you have you will see the molecular wieghts on a graph. You then can compare it to the library you have to see if your sample is actually the sample you say it is.
Chromatography, spectroscopy, flame analysis, mass spectrometry, etc.
Spectroscopy is the analysis of a light source to find which colours are present and which are not. Chromatography is the analysis of a physical substance to find which colours are present and which are not.

Mass Spectroscopy: The paper gave a comprehensive overview on Mass Spectroscopy. The paper discussed the principles of mass spectroscopy, techniques and its application in the field of pesticides. Because of high sensitivity of the techniques, mass spectroscopy has become the powerful analytical tool for monitoring environmental pollutants, pesticides residues in food, water and soil upto parts per billion and/or trillion levels.

chromatography is very important in chemistry,it is used to analyse unknown compounds to determine there structure and much other information,it is also possible to use chromatography to separate mixtures and check for side products in a syntheses.NMR spectroscopy is important in telling how many carbons,hydrogens,etc... are in a compound,this coupled with infared spectroscopy and mass spectroscopy will tell the scientist the size,shape,structure of a compound,as well as what functional groups are present in the molecule Answer: Chromatography is used to analyze, identify, purify & quantify various unknown compounds.Chromatography is used in pharmaceutical industries for the synthesis of various drugs to check whether the product is synthesized from the reactants or not. It is used in petrochemical industries to check the purity of the fuel and its additive. It is also used by forensic scientists & helps them in solving different cases.
During quantitative analysis, deviations can easily occur. Infrared spectroscopy is also not applicable for substances such as complex mixtures.Infrared spectroscopy is hence common combined with other techniques. In quantitative analysis, multivariate techniques are used. As for isomer separation and contaminant detection, gas chromatography-infrared spectroscopy is often used.

To get all of kinds science equipment/apparatus go to Wikipedia.com and look up pH meter, high performance liquid chromatography (HPLC), gas chromatography mass spectroscopy (GC/MS), pipettes, vortex, electrophoresis, and a desiccator. This should get you started.
Everything. About the only thing they have in common is "you learn about them in analytical chemistry class."Except "Nuclear Mass Resonance Spectroscopy", which doesn't exist and I assume is an error that should have read "Nuclear Magnetic Resonance Spectroscopy".X-Ray spectroscopy gives you the conformation in a fairly direct (okay, it's actually not all that direct) manner.NMR spectroscopy mainly gives you chemical structure information; you can finesse it a bit (NOESY and related techniques) to give some conformational information.Mass spectroscopy is pretty much chemical structure only (and, again, it's not all that direct, it just tells you what fragments the molecule breaks apart into; figuring out how they fit together is your problem).

A molecule is the combination of two or more atoms held together by chemical bonds. Scientists have a variety of methods and instruments to determine the composition of molecules including NMR, mass spec, HPLC and routine chromatography, spectroscopy and IR, etc.

no,it is reflection spectroscopy

Liquid chromatography - mass spectrometry. LC is the separation, MS is the detection
Mass spectroscopy can be used for a series of applications, ranging from the determination of chemical elements and chemical compounds in all kinds of samples to the investigation of reactions and interactions of DNA with other substances. As in mass spectroscopy you detect chemical substances based on the ratio between their masses and the charges (only ions can be detected), a wide range of information can be obtained usually with only very low amounts of the substance that you want to investigate.
