Gas Chromotography (1 Viewer)

[FLR-IT]

This is for dot point 1 of Module 3

would someone mind explaining how this technique actually works?

thx

X outline the role of a chemist employed in a named industry or enterprise, identifying the branch of chemistry undertaken by the chemist and explaining a chemical principle that the chemist uses

this one?

reckon it is good idea to remember something general rather than the example in the CC book.

something like, Fred uses AAS to monitor polutants in waste water of BHP

Freds branch is analytical chemistry

etc...

check out the conq chem website (link in the chem section of this site, under all the notes i thinK) because there are additions to the book there and it's there

u reckon u can use AAS??, what principal is being used there

in gas chromotography your using the principle of solubility. different substances will dissolve to differing amounts as the gas travels over the liquid. by analysing the liquid afterwards and comparing it to known information about the solubility of certain substances, they can quantitively determine wat was in the sample. im just writing what i rmber but i tihnk was was in the conc chem book.
AAS involves elements absorbing only a specific wavelength of light. im not sure if this is a physical or chem property.
