“…32,33 The comparison of three selenium-specific devices as chromatographic detectors showed that the absolute detection limit (for 100 ml injection onto the column) was 10 ng, 1 ng and 0.1 ng of Se for FAAS, GFAAS and ICP-MS detectors, respectively. 29 The last system showed also the greatest linear calibration range of 0.01 -10 mg l -1 .…”

“…14 in inorganic selenium speciation analysis. Selenite and selenate are commonly separated by anion-exchange chromatography [28][29][30][31] , although ion-pair reverse-phase chromatography can also be employed. 32,33 The comparison of three selenium-specific devices as chromatographic detectors showed that the absolute detection limit (for 100 ml injection onto the column) was 10 ng, 1 ng and 0.1 ng of Se for FAAS, GFAAS and ICP-MS detectors, respectively.…”

“…Segundo Kölbl (1995), o selênio está presente na crosta terrestre, nos solos, nas águas de rios e oceanos, nos sedimentos e nas amostras biológicas em concentrações que variam de 4.10 -5 mg.Kg -1 a vários milhares de mg.Kg -1 (Tabela III). O conhecimento sobre os compostos de selênio no ecossistema aquático é muito limitado devido à maioria dos trabalhos analíticos neste campo serem feitos para selênio total ou para espécies de selênio inorgânico.…”

“…O conhecimento sobre os compostos de selênio no ecossistema aquático é muito limitado devido à maioria dos trabalhos analíticos neste campo serem feitos para selênio total ou para espécies de selênio inorgânico. Somente poucos compostos orgânicos de selênio foram identificados e determinados em amostras marinhas (Kölbl 1995) (Tabela IV). Vários outros compostos orgânicos de selênio, tais como selenocarboidratos e selenonucleotídeos, podem ocorrer no ambiente marinho, mas ainda não foram identificados.…”
