Determination of Pu isotopes in vegetation using a new on-line FI-ICP-DRC-MS protocol after microwave digestion

Critical comparison of radiometric and mass spectrometric methods for the determination of radionuclides in environmental, biological and nuclear waste samples

“…Combined with an on-line flow through scintillation detector, the 99 Tc in waste samples was determined. The analytical time was only less than 13 minutes per sample [294]. A method by using extraction chromatography (TEVA) in the sequential injection system and direct ICP-MS detection has been reported for the determination of 99 Tc in environmental samples [198].…”

Rapid and automated sequential determination of ultra-trace long-lived actinides in air filters by inductively coupled plasma mass spectrometry

“…However, the application of this method to a radiological event monitoring should be taken with caution, considering that presumably the uranium concentration will be significantly higher than the tolerable maximum level identified for the present method. Contrary to the other automated systems that were developed in the past for the measurement of actinides, 25,29,35,37 this system is designed in such a way that the resins can be reused multiple times. This helps improving the sample throughput and decreases the analytical cost per sample by reducing the amount of resins used.…”

“…[20][21][22][23] The simplicity of the interface of the ICP, which allows coupling with a variety of analytical techniques, including a multi-solvent delivery system (MDS) such as high-performance liquid chromatography on ion-exchange pumps, and its multi-elemental ability are attractive features to develop methods that provide significant sample throughput without sacrificing instrumental sensitivity. 20 Many protocols have demonstrated the analytical capability of ICP-MS for the on-line determination of specific long-lived radioelements in a variety of matrices such urine 24-27 water 28-30 soil, sediment, 3,31-34 biological 3,33 and vegetation 35 samples and food. 36,33 However, most of these protocols lack the multielemental capacity and rapidity required for post-event assessment.…”

Online multichannel ultrasonic extraction for high throughput determination of arsenic in soil by sequential injection slurry hydride generation atomic fluorescence spectrometry

“…Among various sample preparation techniques, ultrasonic or microwave assisted digestion (U/MAD) may be considered as the most suitable techniques in that they have a long history of application to the dissolution of target analytes as the standard methods for sample digestion prior to atomic spectrometric measurement. [6][7][8][9][10][11] However, these techniques require hash conditions such as the use of concentrated acids, high temperatures and high pressures (in the case of MAD). Hence, many efforts have been made to explore other strategies for the treatment of solid samples to minimize the disadvantages of conventional digestion techniques.…”
