Improved precision and speed of thermal ionization mass spectrometry with a multicollector

Multicollector analysis offers the following advantages for uranium analysis: 1. Greatly reduced analysis time; 2. Improved internal errors during data acquisition allowing: (a) Smaller samples to be measured; (b) Greater dynamic ratios to be measured before internal errors become comparable to the external errors; 3. Short data acquisition time giving better results on rapidly fractionating samples; 4. Great tolerance to unstable and rapidly decaying beams resulting in fewer ''unsatisfactory'' analyses
