“…It is also important to stress that this limitation is more relevant for GFAAS than for flame AAS, because in the latter case a fast sequential method may be sufficient in most practical situations, and the current instrumentation already enables such approach. 22 The important point regarding this aspect is that several recent works demonstrate that it is technically possible to monitor a much wider portion of the spectrum simultaneously while still keeping the resolution required, which is always key (monitoring the whole UV-vis with low resolution is not challenging at this point, but such approach is hardly suitable for analysis of complex samples 78 ). In order to do that, Geisler et al proposed the use of laser-driven…”

“…Такой спектрометр имеет компактные размеры и невысокую стоимость [5][6]. Однако при его использовании неизбежны спектральные наложения на аналитические линии определяемых элементов существенно менее чувствительных линий мешающих элементов, содержащихся в анализируемом веществе [7][8]. При превышении определенного уровня концентрации мешающего элемента появляется ошибка в анализе определяемого элемента.…”

“…A ideia de que uma única lâmpada possa ser empregada para a determinação elementar possui maior interesse do que possuir uma HCL (há outras fontes de radiação para determinação em AAS, porém não é o foco da discussão) para cada elemento que vai ser determinado. Desta forma, trabalhos foram conduzidos para que esse objetivo pudesse ser alcançado [12][13][14][15][16][17][18][19][20][21][22][23][24], inclusive atualmente [25,26]. Não obstante, Walsh previu por cálculos que seria necessária uma resolução de 2 pm de comprimento de onda para que uma CS pudesse ser empregada [27], o que seria um real desafio aos monocromadores da época.…”
