Available in PDF, EPUB and Kindle. Book excerpt: The determination of plutonium in urine poses several analytical challenges, e.g., detectability, matrix, etc. We have investigated the feasibility of analyzing plutonium in processed urine by inductively coupled plasma mass spectrometry (ICP/MS). The urine samples are first spiked with [sup 244]Pu as a tracer and internal standard, then processed by co-precipitation and column chromatography using TRU-Spec[trademark], an extraction resin. By enhancing ICP/MS detection capabilities via improved sample introduction and data acquisition efficiencies, an instrumental detection limit of 5 to 50 fg (0.3 to 3 fCi for [sup 239]pu) is typically obtained, depending on the desired degree of quantitation. A brief summary of the analytical method as well as the basis for measuring radionuclides by ICP/MS are submitted; the separation procedure, methods of sample introduction, and data acquisition techniques are then highlighted.

Available in PDF, EPUB and Kindle. Book excerpt: A means of analyzing 99Tc in urine by inductively coupled plasma mass spectrometry (ICP-MS) has been developed. Historically, 99Tc analysis was based on the radiometric detection of the 293 keV E{sub Max} beta decay product by liquid scintillation or gas flow proportional counting. In a urine matrix, the analysis of99Tc is plagued with many difficulties using conventional radiometric methods. Difficulties originate during chemical separation due to the volatile nature of Tc2O-- or during radiation detection due to color or chemical quenching. A separation scheme for 99Tc detection by ICP-MS is given and is proven to be a sensitive and robust analytical alternative. A comparison of methods using radiometric and mass quantitation of 99Tc has been conducted in water, artificial urine, and real urine matrices at activity levels between 700 and 2,200 dpm/L. Liquid scintillation results based on an external standard quench correction and a quench curve correction method are compared to results obtained by ICP-MS. Each method produced accurate results, however the precision of the ICP-MS results is superior to that of liquid scintillation results. Limits of detection (LOD) for ICP-MS and liquid scintillation detection are 14.67 and 203.4 dpm/L, respectively, in a real urine matrix. In order to determine the basis for the increased precision of the ICP-MS results, the detection sensitivity for each method is derived and measured. The detection sensitivity for the 99Tc isotope by ICP-MS is 2.175 x 10−7 " 8.990 x 10−9 and by liquid scintillation is 7.434 x 10−14 " 7.461 x 10−15. A difference by seven orders of magnitude between the two detection systems allows ICP-MS samples to be analyzed for a period of 15 s compared to 3,600 s by liquid scintillation counting with a lower LOD.

Available in PDF, EPUB and Kindle. Book excerpt: With a level of detection of one part in 1015, inductively coupled plasma mass spectrometry (ICP-MS) is a highly sensitive tool in a huge range of analytical applications. Development of the technology continues rapidly, further opening up the scope for this invaluable analytical technique. Despite widespread interest and usage, little has been written to describe the analytical techniques and instrumentation in a format accessible to both new and experienced users of the technique. Inductively Coupled Plasma Mass Spectrometry Handbook provides a thorough description of ICP-MS instrumentation and techniques, giving the reader sufficient knowledge to approach the technique with confidence.

Book excerpt: Mass spectroscopy has the distinct advantage of detecting atoms rather than radioactive decay products for nuclides of low specific activity. Electrothermal vaporization (ETV) is an efficient means of introducing small volumes of prepared samples into an inductively coupled mass spectrometer to achieve the lowest absolute detection limits. The operational characteristics and capabilities of electrothermal vaporization inductively coupled mass spectrometer mass spectroscopy were evaluated. We describe its application as a detection method for determining Pu in urine, in conjunction with a preliminary separation technique to avoid matrix suppression of the signal.
