Which of the following is the definition of spectral
interference in plasma and flame atomic emission
spectrometry?
Spectral interference can alter the aspiration, nebulization,
desolvation, or volatilization processes.
Spectral interference occurs due to the oscillation frequency of
fluorescent lights used to illuminate the laboratory workspace.
Spectralinterference can occur when easily ionized substances
alter the ionization of the analyte.
A spectral interference in atomic spectroscopy occurs when a
spectral line of an element in the sample matrix overlaps that of
the...
Heat effects of chemical or physical processes can be measured in a calorimeter.
Can someone please paraphrase this to me.... if possible.
Heat effects of chemical or physical processes can be measured
in a calorimeter. Instruments of widely varying designs are
employed to accommodate the large range of experimental conditions
encountered. For instance, the heat effects to be measured may
range from milliJoules to milliliter, quantities involved from
fractions of milliliters to hundreds of milliliters and from
milligrams to grams, operating temperatures from below liquid
helium temperature (4.2 K) to 2000o C, and...

Atomic absorption spectrometry was used with the method of
standard additions to determine the concentration of cadmium in a
sample of an industrial waste stream. For the addition, 10.0 μL of
a 1000.0 μg/mL Cd standard was added to 10.0 mL of solution. The
following data were obtained: Absorbance of reagent blank = 0.041
Absorbance of sample = 0.476 Absorbance of sample plus addition =
0.821 What was the concentration of the cadmium in the waste stream
sample?Later, the analyst...

The magnesium in a series of soil samples was characterized by
atomic absorption spectrometry (AAS). The instrument was calibrated
with a series of standards: 0, 50.00, 100.00, 250.00 mg/L
MgSO47H2O. These samples produced average instrument readings of
0.005; 0.192 ; 0.401 ; and 0.993. Triplicate analysis of an unknown
yielded instrument readings of 0.328, 0.340, 0.335. What is the
average concentration and standard deviation of the unknown? Report
your answer as ppm Mg. THE OPTION IS NOT 211
