Effect of absorption-tube shape on hydride generation for trace selenium determination in flame-in-tube atomic absorption spectrometry.

Determination of trace selenium in urine by derivative hydride generation atomic absorption spectrometry.

On-line hyphenation of hydride generation with in situ trapping flame atomic absorption spectrometry for arsenic and selenium determination.

The analytical performances of coupled hydride generation, integrated atom trap (HG-IAT) atomizer flame atomic absorption spectrometry (FAAS) systems were evaluated for determination of As and Se in biological and environmental reference materials. Arsenic and Se hydrides are atomized in air-acetylene flame-heated IAT. A new design of HG-IAT-FAAS hyphenated technique that would exceed the opera...

Interferences study for Selenium determination using of on Liquid Nitrogen Trap Hydride generation atomic absorption Spectrometry

A method has been developd determine selenium by hydride generation atomic absorption using nitrogen trapping technique. A series of experiments was performed to obtain the optimum condition. The results show that this method has the advantage of being sensitive, accurate, rapid and simple. Transition metal and other hydride forming elements interferences on the determination of selenium was st...

Hydride Generation-in situ Trapping-flame Atomic Absorption Spectrometry Hybridization for Indium and Thallium Determination

O desempenho analítico do acoplamento de geração de hidretos com sistema de aprisionamento de átomos (HG-IAT) em espectrometria de absorção atômica com chama (FAAS) foi avaliado para determinação de In e Tl em material de referência. Hidretos de índio (InH 3 ) e tálio (TlH) foram atomizados em sistema IAT aquecido em chama ar-acetileno. Investigou-se um novo arranjo da técnica hifenizada HG-IAT...

Determination of selenium in Teucrium species by hydride generation atomic absorption spectrometry.

Hydride generation atomic absorption spectrometry (HGAAS) was applied for determination of selenium content in dried aerial parts of wild and cultivated Teucrium species (Lamiaceae) growing in Croatia: T. arduini L., T. chamaedrys L., T. flavum L., T. montanum L., T. polium L., and T. scordium L. subsp. scordioides Schreb. Special attention was paid to the wet oxidation procedure for the sample...
