Question

Map sapling learning Watch the animation of the beam chopping method of background correction in atomic absorption spectroscopy. Then, answer the question below Hollow Cathode Detector Lamp Chopper Burner Head Which of the following describe(s) the beam chopping method of background correction? Check all that apply. uses a magnetic field to split the absorption line of analyte atoms into three components corrects for scattering uses the difference in signals when the lamp is blocked and when the lamp is not blocked to give the desired analytical signal corrects for flame emission most common method of background correction for atomic absorption

Explanation / Answer

first one is wrong it is not using any magnetic field .3rd and 5th options are correct.Chopper uses difference in signals when blocked.and it is the most common method.It correct the signal for flame emission spectrascopy 4th option is also correct
