“…The chemical analysis of such dissolution using flame-based optical spectrometry indicated the 70 content of each REE label on the testing area. 41 This procedure is used by organizations such as the OSHA 42 in studies of exposure levels and threshold limit values for different metals. In our case, we have monitored the concentration of the lanthanide labels.…”

“…Several standard methods have been promulgated that utilize these reagents. 11,14,27,[34][35][36][37][38][39] Based on the data analysis of this work, the interlaboratory data also show conclusively that sample preparation using nitric acid alone, or combinations of nitric and hydrochloric acids, is not effective for complete extraction of Be from high-fired BeO. It is noted that the use of HNO 3 alone or in combination with HCl or HClO 4 may be suitable for dissolving Be from some matrices, but the results herein indicate that HNO 3 should not be the sole or primary acid employed when the sample is expected to contain refractory BeO.…”

Occupational sampling and analysis for multiple elements is generally approached using various approved methods from authoritative government sources such as the National Institute for Occupational Safety and Health (NIOSH), the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA), as well as consensus standards bodies such as ASTM International. The constituents of a sample can exist as unidentified compounds requiring sample preparation to be chosen appropriately, as in the case of beryllium in the form of beryllium oxide (BeO). An interlaboratory study was performed to collect analytical data from volunteer laboratories to examine the effectiveness of methods currently in use for preparation and analysis of samples containing calcined BeO powder. NIST SRM(®) 1877 high-fired BeO powder (1100 to 1200 °C calcining temperature; count median primary particle diameter 0.12 μm) was used to spike air filter media as a representative form of beryllium particulate matter present in workplace sampling that is known to be resistant to dissolution. The BeO powder standard reference material was gravimetrically prepared in a suspension and deposited onto 37 mm mixed cellulose ester air filters at five different levels between 0.5 μg and 25 μg of Be (as BeO). Sample sets consisting of five BeO-spiked filters (in duplicate) and two blank filters, for a total of twelve unique air filter samples per set, were submitted as blind samples to each of 27 participating laboratories. Participants were instructed to follow their current process for sample preparation and utilize their normal analytical methods for processing samples containing substances of this nature. Laboratories using more than one sample preparation and analysis method were provided with more than one sample set. Results from 34 data sets ultimately received from the 27 volunteer laboratories were subjected to applicable statistical analyses. The observed performance data show that sample preparations using nitric acid alone, or combinations of nitric and hydrochloric acids, are not effective for complete extraction of Be from the SRM 1877 refractory BeO particulate matter spiked on air filters; but that effective recovery can be achieved by using sample preparation procedures utilizing either sulfuric or hydrofluoric acid, or by using methodologies involving ammonium bifluoride with heating. Laboratories responsible for quantitative determination of Be in workplace samples that may contain high-fired BeO should use quality assurance schemes that include BeO-spiked sampling media, rather than solely media spiked with soluble Be compounds, and should ensure that methods capable of quantitative digestion of Be from the actual material present are used.

“…Further interlaboratory evaluations were proposed and this reviewer recommends, if possible, the use of real matrix samples to assess the performance of the key digestion step. Ashley et al 80 also undertook an intercomparison exercise to ascertain the performance of a field-based fluorescence method for the determination of trace levels of Be in polyvinyl alcohol wipes used in surface swabbing monitoring exercises. Test wipes were spiked with a BeO CRM material to provide spiking levels in the range 0.03 to 5.6 mg Be/wipe.…”

This is the 27th annual review published in Journal of Analytical Atomic Spectrometry of the application of atomic spectrometry to the chemical analysis of environmental samples. This Update refers to papers published approximately between September 2010 and August 2011 and continues the series of Atomic Spectrometry Updates (ASUs) in Environmental Analysis 1 that should be read in conjunction with other related ASU reviews in the series, namely: clinical and biological materials, foods and beverages;(2) advances in atomic spectrometry and related techniques;(3) elemental speciation;(4) X-ray fluorescence spectrometry(5) and industrial analysis: metals, chemicals and advanced materials.(6) To celebrate the 25th anniversary of JAAS, a 25-year retrospective of ASU reviews has been published(7) to highlight the development and evolution of atomic spectrometric techniques and their use in measurement applications. Specific to this review, in the field of air analysis there is ongoing interest in measuring atmospheric Hg species and evaluating procedures for the determination of the carbonaceous content of airborne particulate matter. In a measurement arena where RMs are relatively scarce, a number of useful interlaboratory comparison studies have been reported. In the field of water analysis, as in previous years, the main areas of activity are the development of preconcentration and extraction procedures and elemental speciation protocols for elements such as As, Cr and Hg. There is increasing interest in evaluating TXRF for trace analysis. In the field of soil and plant analysis, sample dissolution and extraction remain a major focus of interest-especially methods to assess bioavailability-and there is a hint that 'greener' approaches, using less concentrated acid, are becoming important. Especially notable are the continued developments in LIBS, a shift towards more widespread use of techniques such as HPLC-ICP-MS and synchrotron-based XRF, and growth in studies where multiple techniques have been applied to the same sample for trace element mapping or speciation analysis. Less desirable are the publication of variants on well-established analytical methods with marginal novelty and several instances where substantially similar articles appeared almost simultaneously in more than one journal, thus generating 'two publications for the price of one'. It is evident that MC-ICP-MS and LA-MC-ICP-MS are now so widely available in geoanalytical laboratories that applications papers, that include little of novelty from an analytical perspective, dominate the literature. However, this trend should not mask the vital research required to underpin and improve the quality of the geochemical data on which any interpretation is based. Another observation is the high proportion of analytical and applications papers with Chinese authors, reflecting the rise of atomic spectrometry in China over the past number of years.
