Figures of Merit
The correctness of a measured value.
What is accuracy?
Technique that relies on solutions containing only the known analyte concentration.
What is external calibration?
An instrument that can be operated such that an ion is first selected, then fragmented, then analyzed.
What is triple quadrupole MS?
The equation describing the ideal linear relationship involved in spectrophotometry
What is Beer's Law?
An hourglass.
What is the broad organization of scientific writing shaped like?
The absolute variation in a set of measured values.
What is standard deviation?
Attribute of an ideal calibration bestfit line.
What is an R^2 = 1?
An instrument that could be used to analyze the pigments of the Mona Lisa.
What is a Raman spectrometer?
The methods of mass transport in electrochemistry.
What is diffusion, migration, and convection?
A step a writer takes for achieving a specific purpose/goal.
What is a move?
The degree to which small differences in analyte concentration result in measurable differences in signal.
What is sensitivity?
Technique that relies on solutions containing known amounts of analyte and of a second substance that is added to all sample types.
What is internal calibration?
A mass spectrometry technique that yields spatial information (i.e., “imaging”).
What is MALDI?
The type of ICP-MS interference caused by isotopes of different elements having the same mass.
What is an isobaric interference?
A sentence that identifies an unanswered question or under-explored research area that will be addressed in the writing.
What is the gap statement?
The degree to which a method works well despite small differences in stir plate vigor.
What is robustness (or ruggedness)?
All else equal, the region of the calibration curve where uncertainty is the lowest.
What is the middle of the calibrated concentration range?
A “greener” separation technique.
What is supercritical fluid chromatography?
The parameter/metric that reflects a high efficiency separation.
What is a low height of a theoretical plate (or a high number of theoretical plates)?
Suggest broader implications or applications of your work.
What is a submove in the discussion/conclusion section?
The degree to which a signal is due to the amount of analyte alone and not to other substances in solution.
What is selectivity?
The calibration cause for calculating a negative value for analyte concentration.
What is a positive, non-zero, y-intercept for the bestfit line?
An extremely sensitive instrument that can be used to analyze one element from a very small sample.
What is graphite furnace AAS?
The physical phenomenon that results in a diffraction grating spreading out wavelengths of light at different angles.
What is constructive/destructive interference?
Good morning, class.
What is "Is it, and how do we know?"
