The present study was undertaken to quantitatively measure the concentration of ions produced by a microwave discharge source commonly used in the production of atomic species. Using a double floating probe to monitor the ion content, the results indicate that the flow of ions was less than 1.8 × 10 −6 times the total flow of particles from the discharge cavity. Due to the low ion mole fraction, it is concluded that ion‐molecule reactions are not competitive with previousry reported atom‐molecule reactions.
