Question
Inductively coupled argon plasma does not suffer from many of the interferences encountered with flame atomic spectroscopy. Which of the statements below are NOT advantages of plasma over flame?
Plasma is twice as hot as conventional flame.
Formation of analyte oxides and hydroxides is negligible.
Atomization is more complete and signal is enhanced.
Analyte residence time in the plasma is about twice as long as in flame.
None. All of these statements are true.
a)Plasma is twice as hot as conventional flame.
b)Formation of analyte oxides and hydroxides is negligible.
c)Atomization is more complete and signal is enhanced.
d)Analyte residence time in the plasma is about twice as long as in flame.
e)None. All of these statements are true.
Explanation / Answer
Option E
All above are correct . Plasma has been very advantageous in term of temperature, atomisation, residence time.
