ACHEM Chemical Analysis Flashcards
Involves the application of methods and techniques to obtain specific objective quantitatively and qualitatively including the structural information on the nature of matter.
Analytical Chemistry
Involves the application of methods and techniques to obtain specific objective quantitatively and qualitatively including the structural information on the nature of matter.
Analytical Chemistry
Also known as wet chemical analysis which uses purely chemicals
Classical Techniques
Measures the contamination in terms of shipping and laboratory sources
Trip blank
The standard in this method became regulatory
Regulatory method
Systematic procedure to achieve specific objectives using specified techniques
Method
Have the highest metrologicql qualities whose operation can be described and understood instantly
Primary Method
Measures the contamination in laboratories sources
Method or Instrument blank
Set of written instructions on how to apply method in a particular sample
Procedure
E method to measure or determine chemical of physical properties of an element, mixture or substance
Analytical Techniques
Set of guidelines for analysis specifically created by a company
Protocol
Use to analyse large number of samples in short period of time to identify samples that give too (+) result
Screening
Graphite Furnace Atomic Absorption Spectro is an example of
Tech, meth, procedures or protocol
Techniques
Signal is either for analyte, matrix, or blank and have the lowest concentration of noise (analyte) in test sample that is distinguished from zero
Limit of Detection
Same of lod but with reasonable precision and accuracy
Limit of quantification
In most instrumental method, it is applied only when it is possible to determine the BASELINE NOISES obtained from BLANK DETERMINATION
Noise ratio or Based on numerical value of signal
A sample that contain all the components except analyte
Blank
It is an indication of reproducibility or a measurement
Precision
Chemical analysis qre affected by these types of errors
Gross, systematic and random errors
The focus of interest in the sample or the one being analyze
Analyte
They are often large and may cause a result to be either high or low
Gross errors
