Week 1 Flashcards
is a branch of chemistry that deals with the study of different methods, techniques, and instruments separating, identifying and/ or determining the amount of analyte present in a sample
Analytical chemistry
component of the sample that is to be determined
analyte
it deals with identifying the constituent present in a material
Qualitative analysis
it deals with determining the amount of a constituent or analyte present in a given material
Quantitative analysis
it deals with the analysis of elements and inorganic compounds
inorganic analysis
it deals with the analysis of carbon and its compounds
organic analysis
classification of quantitative analysis
- based on composition of sample
- based on sample size
- based on type of constituent
- based on final measurement
Based on composition of the sample
- complete analysis
- partial analysis
- elemental analysis
- molecular analysis
it is the amount of all constituents present in a sample is determined
complete analysis
A complete analysis of boiler water would be ____,_____,______,_______,______, and _____
alkalinity
pH
hardness
phosphates
silica
dissolved oxygen
the amount of specific elements are determined
elemental analysis
the amount of molecular compounds are determined
molecular analysis
based on sample size
macro analysis
semi-micro analysis
micro analysis
ultra micro analysis
analysis that is done on a sample weighing more than 0.1 g
macro analysis
analysis on samples weighing between 0.01 g and 0.1 g
semi-micro analysis
analysis on samples weighing between 10^-4 to 10^-2
micro analysis
analysis on samples weighing less than 10^-4
ultra micro analysis
the amount of a particular constituent is determined
partial analysis
Based on type of constituent
- major constituent analysis
- minor constituent analysis
- trace constituent analysis
- ultra trace constituent analysis
concentration level of the analyte is between 1% - 100%
major constituent analysis
concentration level is between 0.01% (100 ppm) to 0.1%
minor constituent analysis
concentration level is between 1 ppb to 100 ppm
trace constituent analysis
concentration level is less than 1 ppb
ultra trace constituent analysis
Based on final measurement
gravimetric analysis
titrimetric/ volumetric analysis
physicochemical analysis
electroanalytical analysis
spectroscopic analysis
