Considering real safeguards samples, the typical situation is that one has to deal with an unknown number of particles that can differ in their isotopic signatures.
Considering real safeguards samples, an individual selection of the particles to be analyzed is often not feasible using LA-MC-ICPMS without pre-selection by means of e.g. fission track or scanning electron microscopy.
Development of standard operating procedures and quality control plans is a safeguard of the samples' quality and of the validity of the analyses results.
Credited to four directors of photography, the movie is never less than stunning, especially when visiting the Svalbard Global Seed Vault in Norway, which houses thousands of samples to safeguard against crop devastation, or poking around a gritty recycling plant in Mumbai.
This is to safeguard against loss of samples through unforeseen events like equipment failure.
Police officials suspended DNA testing at the laboratory after an audit completed in December found a host of problems with its methods, including poor calibration and maintenance of equipment, improper record keeping and a lack of safeguards against contamination of samples.
Under the new guidelines, researchers wishing to use medical information without seeking patient consent will have to ensure that certain additional procedures, such as safeguarding the confidentiality of human samples and destroying identifiers that could be used to trace individuals, are followed.
Matching over a short period around event dates helps to safeguard against the risk of sampling bias, whose impact, if at all present, should be negligible in time comparisons over short horizons.
Lastly, while ethical norms generally support transfer of data and samples with certain safeguards, there is continuing debate about the parameters of that transfer and the various organisational safeguards, technological measures, and physical measures that should be adopted and updated – and disclosed – in the consent form.
Application examples are given to identify isotopes in various samples, typical for qualitative safeguards verification tasks – attribute tests.
