|
This type of analysis answers the question " how much of the sample? " |
Quantitative analysis |
|
|
What are the two types of chemical analyses |
Absolute and relative analyses |
|
|
This type of chemical analysis is based on reaction stoichiometry |
Absolute analysis |
|
|
Two types of Absolute analysis |
Gravimetric and volumetric analysis |
|
|
This type of chemical analysis is done through comparison of properties |
Relative analysis |
|
|
This type of absolute analysis measures the mass of the sample |
Gravimetric analysis |
|
|
This type of absolute analysis determines the volume of the sample |

|
|
What is IUPAC |
International Union of Pure and Applied Chemistry |
|
|
Another term for absolute analysis |
Classical method of analyses |
|
|
Another term for relative analysis |
Instrumental method of analysis |
|
|
The study of the separation, identification, and quantification of the chemical components of natural and artificial materials. |
Analytical chemistry |
|
|
Examples of instrumental methods of analysis. |
Optical, electrochemical, and chromatographic methods. |
|
|
Differentiate selective and specific reactions |
selective reaction- occurs with few analytes specific reaction- occurs only with one analyte |
|
|
This sample consists of several portions of the material to be tested |
Gross sample |
|
|
This sample is a small portion of the gross sample |
Laboratory sample |
|
|
This sample is the one actually being analyzed |
analysis sample |
|
|
What type of mixture should the sample be for analysis if spatial structure isn't of interest. |
It must be homogeneous |
|
|
Considerations before sampling blood |
1. Condition of the blood 2. analyze whole blood/plasma/serum? |
|
|
differentiate whole blood, plasma, and serum |
whole blood- clotted blood plasma - liquid from unclotted blood serum - liquid from clotted blood |
|
|
This method is used t destroy trace metals |
Dry ashing |
|
|
This method is used to destroy organic matter by heating with oxidizing acids |
Wet digestion |
|
|
Another term for volumetric analysis |
Titrimetric analysis |
|
|
Thee type of sample is taken for analysis in order to obtain statistical data on the precision of the analysis. |
replicate samples |
|
|
3 ways to remove proteins from the sample |
1. wet digestion 2. dry ashing 3.precipitating proteins with various reagents and filtered/centrifuged away |
|
|
What do you call a sample from which all proteins have been removed. |
Protein-free filtrate (PFF) |
|
|
How to prepare a dry basis solid sample |
1. Dry in an oven at 110 to 120 degrees Celcius for 1-2hrs 2. Cool the sample in a dessicator 3. weigh |
