The article discusses a method for determining the atomic fraction of isotopes in boron trifluoride, boron carbide, boron anhydride, ferroboron and boric acid, by converting them into potassium tetrafluoroborate. This compound is then analyzed using the spectrometric electron bombardment method. This technique is known for its high accuracy and “self-verifying” capabilities, meaning that the mass fraction of isotopes can be calculated using different mass lines, allowing for the identification of any potential errors.
