| To obtain a weighable mass a dedicated set-up for the low energy beam transport of heavy ions is needed. |
| The absorbency of nitric acid ions in the solution is measured using UV absorptiometer at a wavelength of 220 nm. |
| In Q-Tof mass spectrometers ions are focused by a radio frequency lens before transmission to the quadrupole. |
| The hydrated protein-lipid system was solvated in a water bath including chloride and sodium ions at physiological concentration. |
| An electronic cleaner produces negative ions that are attracted to the pollutants. |
| Anyone without achlorhydria secretes hydrogen ions from gastric mucosa whether fed orally, by a nasogastric tube, or parenterally. |
