what is analytical chemistry?

Answer 1

Analytical Chemists measure things.

This is a very broad generalisation, but essentially an analytical chemist measures a quantity in order to elucidate the composition of a mixture or the structure of an unknown compound.

Analytical Chemists are found in a broad range of industries and professions. Not all chemists wear white coats, in fact many forensic scientists start out their career as analytical chemists.

Some common tools used by analytical chemists are:

1. Mass Spectra - this technique at a crude level will give you the molecular weight of a compound but on a more elegant level will also allow for some structural elucidation.

2. HPLC (High Performance Liquid Chromatography) - this technique allows a chemist to separate the components of a mixture by their affinity to certain substrates packed into a column and provides quantitative information on the amount of each component in a mixture. When coupled to a range of detectors such as Mass Spectrometer, NMR, or even a simple diode array detector can give very powerful technique to elucidate the composition of an unknown mixture.

Answer 2

In analytical chemistry, a scientist performs a series of tests to either 1) identify an unknown compound; or 2) quantify a property of a known compound.

In application, a physician may want to know the amount of a drug in a person's blood. He/She will (i'm simplifying here) dissolve the blood in a solution. Then the solution will be injected into a machine that separates components (liquid chromatograph). Then each component will be identified by its molecular weight (mass spectrometer).

There are thousands of different applications. If you are interested, go to your local college bookstore and get an analytical chemistry book.

Answer 3

The classic answer to your question is that "Analytical Chemistry is what Analytical Chemists Do."

Analytical chemistry ranges from the lowly lab tech following a recipie for a simple qualitative analysis to the University researcher studying fundamental aspects of the interactions of light with matter. I have done both and everything in-between, from simple qualitative tests to modifying and optimizing analytical methods, to University research.

Analytical Chemistry answers the questions of "What is it?" and/or "How much of it is there?".

Analytical Chemistry is divided into several major sub specialties, including electrochemistry, spectroscopy, mass spectrometry, surface analysis, chromatography, and "wet chemistry".

Answer 4

Analytical chemistry is the analysis of material samples to gain an understanding of their chemical composition, structure and function.

Answer 5

analysis urine sample,analysis of blood of malarial patient, melting point and boiling point

Answer 6

nicely, you could take this after taking gen chem (a million year), i think of it truly is lots extra clever to take it now truly of when you clog your suggestions up with organic and organic chemistry and biochem. there's a great sort of math and algebra in contact and you ought to undergo in suggestions most of the inorganic chemical reactions from gen chem like what compounds variety precipitates. there's a sprint thermodynamics, even yet it truly is especially stoichiometry problems and a great sort of titrations, buffers and acid base chemistry. in case you do no longer suggestions that, decide for it with the aid of fact now may be the main suitable time to do it. additionally, 2 words: team artwork

Answer 7

it is both qualitative and quantitative analysis of chemicals. you must understand the meaning of these three terms:
a- A chemical is that defined by a fixed formula, physical,chemical properties. No two chemicals are identical though they both may possess the same emperical formula.
b- quantitative analysis is that mean by which we can identify the chemical.
c- qualitative analysis helps to determine the amount of a chemical which may be expressed in grams,per cent, per million , ..............
Both types of analyses need physical, chemical and biological means to access the truth.

Answer 8

analytical chemistry is basically used for identifying different compounds by recognizing their various properties and reacting them wid different substances........like if a metal reacts wid ammonium hydroxide to give a gelatinous white precipitate, then it is zinc........

Answer 9

A science in which one or more of a substance's constituency is determined qualitatively and quantitatively using chemicals of known concentrations.
