Spectroanalytical Methods

Spectroanalytical methods measure the wavelength and intensity of radiations that are either emitted or absorbed by a molecular or atomic species. These methods are useful for evaluating the electronic or atomic arrangement of the molecules of a given analyte.

Question

A GC detector that ionizes each components of the sample and the
mass is repeatedly scanned during the chromatographic experiment. It
uses ion sources such as ion-impact or chemical ionization
Flame photometric detector
Atomic emission detector
Option 1
Mass spectrometer
Analysis of an unknown plant extract yield two peaks X and Y in a
chromatogram, 15.65 and 17.03 min respectively in a 30.0 cm column.
The peak base width for X is 1.06 and 1.15 for Y. The average number of
plates in the column is
3.50 x 10^3
3.51 x 10^3
3.52 x 10^3
The following statements are true except-*
The number of theoretical plates of a chromatograph is directly proportional to the
square of the retention time
The calculated variance of a Gaussian curve is directly proportional to the plate height
but inversely proportional to the column length.
The standard deviation of the Gaussian curve can be calculated as one-fourth the
ratio of the products of the column length and range to the retention time
