Question
Which working curve would be least likely to be observed for ICP emission spectrochemical analysis of iron in fresh water? What is the mechanism that produces the high temperatures in an inductively coupled plasma? The argon gas reacts with oxygen from the air, releasing energy that heats the gas. The oscillating magnetic field causes polar water molecules from the sample solutions to move fast and collide with other particles, heating them up. Free electrons and argon ions oscillate in the radio frequency magnetic field and collide with other gas phase particles, transferring energy to them and heating them up. The quartz in the torch absorbs the radio frequency radiation from the coil and heats up. The heat is transferred to the argon gas and the solutions as they pass through the torch. An atomic absorption spectrometer is equipped with both, a flame atomizer a graphite furnace. Which combination of precision and sensitivity is correct? flame atomizer graphite furnace graphite furnace flame atomizer graphite furnace graphite furnace flame atomizer flame atomizerExplanation / Answer
Answer;
,1.. option (A ) is correct because Fe in ICP show there graph as per concentration increases which is ppm on high concentration plot for emission never parellel respect it.it will strengthen.
2.. option (d) is correct because argon gas is inert so high amount of energy needed for ionisation which takes in torch area in presence of megnetic field.and 10000degree temperature increases.
3. Option (A) is correct because graphite is peramegnetic show electronic sensitive while
Flame atomiser atomized sample and make it precision level.
