Abstract
A new atom identification and detection technique for ultrasensitive mass spectrometry has been applied to the radionuclide 36Cl. Measurements of the 36Cl/Cl ratio in AgCl precipitated from six different natural water samples fell in the range 1.2 × 10−13−2 × 10−12 with a background level below 3 × 10−15. For each sample 70 mg of AgCl was used, requiring 1–51 of water.
