Question

All of the following are background correction techniques for atomic spectroscopy, except: Select one: the analyte sample is spiked with a compound to absorb al background signal. subtraction of adjacent pixel height from signal pixel height for a charge injection detector. the absorbance and scattering of the light from a D_2 lamp is measured and subtracted from the absorbance and scattering of light from a hollow-cathode tube. a strong magnetic field is pulsed on and off. The sample and background is observed when field off. Only the background is observed when the field is on. The absorbance difference is the analyte signal. a rotating beam chopper periodically blocks the analyte signal, allowing for a background measurement.

Explanation / Answer

All of the following are background correction techniques for atomic spectroscopy except

The anlalyte sample is spiked with a compound to absorb all background signal

atomic spectroscopy ,

a sample is subjected to a high energy , warm condition keeping in mind the end goal to create excited state atoms , fit for radiating light.

The energy source can be an electrical curve, a fire, or all the more as of late, a plasma. The discharge range of a component presented to such a energy source comprises of a gathering of the admissible outflow wavelengths, generally called emanation lines, in light of the discrete way of the produced wavelengths. This emanation range can be utilized as a one of a kind trademark for subjective recognizable proof of the component. Nuclear emanation utilizing electrical circular segments has been generally utilized as a part of subjective analysis.Emission methods can likewise be utilized to decide the amount of a component is available in an example. For a "quantitative" investigation, the power of light discharged at the wavelength of the component to be resolved is measured. The discharge power at this wavelength will be more prominent as the quantity of molecules of the analyte component increments. The system of fire photometry is a use of atomic emission for quantitative investigation.
