Modern Method
Instrumental Method
Collection of all the components in the sample containing analyte
Matrix/Sample Matrix
Ion in an aqueous solution
Electrolyte
It is also called as central science
Analytical Chemistry
Technique apply to a few analyte
Selective
Technique to use for one analyte
Specific
Species other than analyte
Interferants
It is also called as expiry
Self-life
Process of collecting mass sample
Sampling
Devised to isolate analyte from interference
Scheme
Improves quality of the result
Replication
Same size carried through an analytical procedure
Replication
Determines the mass of analyte
Gravimetric method
Measures the electrical properties such as potential, current, resistance, quantity of electrical change
Electroanalytical Method
Interaction between electromagnetic radiation and analyte atoms
Spectroscopic method
Measures the volume of a solution
Volumetric Method
Compromise of accuracy, time and money
Select Method
Process of collecting small mass
Sampling
It eliminates the substances from the samle
Eliminating Interferences
Determines the proportionality between analyte and a measured quantity
Calibration
True or False: Analytical results are complete when their reliability has been estimated
True
Process of continues measurement and control
Feedback system
Cycle of measurement, comparison, and control
Feedback loop
Mostly used of biological, biomedical system, mechanical, and electronics
Feedback system
A compound reagent used in determining arsenic
Diethyldithiocarbomate (C6H10NS2)
It measures the intensity
Spectrophotometer
Common ingredient of herbicide
Arsenic (As)
Used to determine the agent of herbicide
Quantitative analysis
Soluble in water and use as the active ingredients in many herbicide
Methlarsonic acid (CH3ASO(OH)2)
Process of converting organic matrix to carbon dioxide and water. Involved heating
Dry Ashing
Toxic, colorless gas that is evolved when H3AsO3 is treated with zinc
Arsine (AsH3)
Molecule important in analytical chemistry
Arsine (AsH3)
True or False:
Arsenic can be separated from other substance that may interfere in analysis, converting it to arsine
True
Use to determine the concentration of the two unknown solutions
