“…12 Moreover, the internal standard method (ISM) coupled with SAM (i.e. ISM-SAM) has been used in measurements by proton-induced X-ray emission, 15 photon and/or proton activation, [16][17][18][19][20] phosphorescence, 21 and screen-printed electrodes 22 to improve the analytical precision. In recent years, ISM-SAM was also investigated for measurement by ICP-MS, 13,14 and contributed to a better analytical performance with accuracy and precision comparable to those obtained by an isotopedilution (ID) approach.…”

“…Подобные исходные посылки закономерно привели к тому, что три указан ных вы ше способа количественных определений (внешнего стандарта, абсо лют ной гра дуировки и стандартной добавки) оказалось целесообразным модифицировать за счет введения в образцы дополнительных стандартов. Для способа внешнего стан дарта этот прием известен достаточно давно [1,5,6], но, как ни удивительно, он не достаточно представлен в учеб ных руководствах или монографиях. Для исправ ле ния такой ситуации рассмотре нию этой проблемы была посвящена серия публика ций [7][8][9][10][11][12].…”
