The bottom of the meniscus.
What is the specific point on a liquid's surface that should be read to ensure accurate volume measurement in volumetric glassware?
A method that separates particles by their mass-to-charge ratios.
What is mass spectrometry?
An hourglass.
What is the broad organization of scientific writing shaped like?
The slope of a calibration curve.
What is sensitivity?
What is internal calibration
The amount of liquid delivered using TC glassware, compared to when using otherwise equivalent TD glassware.
What is less?
Changing the potential over time while measuring the current.
What is voltammetry?
A mini-version of a research article including components of the introduction, methods, results, and discussion.
What is an abstract?
The absolute variation in a set of measured values.
What is standard deviation?
Attribute of an ideal calibration equation.
What is an R^2 = 1.
A volumetric flask.
What is the best glassware for making analytical solutions?
An instrument that can detect elements at trace-level concentrations.
What is ICP-MS?
A specific section of writing that advances a specific purpose or goal.
What is a move?
The relative amount of variation in a set of measured values.
What is %CV or RSD?
All else equal, the region of the calibration curve where uncertainty is the lowest
What is the middle of the calibrated concentration range?
The process of diluting a solution to create the next more dilute solution, and then using that more dilute solution to create the next more dilution solution, etc.
What is serial dilution?
An instrument that collects an entire absorption spectrum at one time.
What is an array spectrophotometer?
Suggest broader implications or applications of your work.
What is a submove in the discussion section?
The degree to which the measurement reflects the amount of the analyte alone, without interference.
What is selectivity?
The calibration cause for calculating a negative value for analyte concentration.
What is a non-zero (positive) y-intercept for the bestfit line?
The physical reason we aspirate and dispense fluid three times prior to delivering a volume with a micropipet.
What is to humidify the air within the micropipet tip?
A separation technique that retains non-polar analytes more strongly in the stationary phase than the mobile phase.
What is reverse-phase chromatography?
It depends on the story.
What is everything?
