Interlaboratory comparison of cosmogenic 21 Ne in quartz [PDF]

Quaternary Geochronology, 2015
We performed an interlaboratory comparison study with the aim to determine the accuracy of cosmogenic 21Ne measurements in quartz. CREU-1 is a natural quartz standard prepared from amalgamated vein clasts which were crushed, thoroughly mixed, and sieved into 125–250 μm and 250–500 μm size fractions.

Evaluation of PCR-Based H5N1 Influenza Detection Methods in Milk from an Interlaboratory Comparison Study Demonstrating Method-Dependent Sensitivity Variability

Journal of Food Protection
Since March 2024, H5N1 highly pathogenic avian influenza (HPAI) has been detected in U.S. dairy cattle. Infectious virus shed in unpasteurized milk, a matrix not previously evaluated for H5N1 detection, makes real-time reverse transcription quantitative ...

Estimation of consensus value of interlaboratory measurement results accompanied by a minimum increase in associated uncertainty

Стандартные образцы, 2020
In this article, the author proposed a method for estimating the consensus value of interlaboratory measurement results, which makes it possible to reduce the uncertainty of the consensus value in comparison with the known methods. The method is based on

Beyond Chemical Compliance: A Critical Review Toward Microbiome‐Informed Ecological Exit Criteria for Bioremediated Soils

Land Degradation &Development, EarlyView.
ABSTRACT Chemical compliance remains the usual endpoint for closing contaminated‐soil remediation projects, although it does not establish recovery of soil function or the durability of the post‐treatment state. This critical review examines when microbiological evidence can contribute to ecological closure decisions.

Interlaboratory comparison of the measurement of albumin in urine

Clinical Chemistry, 1991
Abstract Because of increased interest in the assay of albumin in urine and the sensitivity required to quantify concentrations associated with (a) increased risk of developing end-stage renal disease and cardiovascular disease among people with diabetes and (b) renal damage caused by exposure to nephrotoxic substances, we conducted a ...

Flow cytometric phytoplankton concentration and optical properties across instruments and laboratories

Limnology and Oceanography: Methods, EarlyView.
Abstract Flow cytometry measures the optical properties of individual cells and has become essential for enumerating and characterizing marine phytoplankton. Yet systematic comparison of measurements across instruments remains limited, hampering data comparison across laboratories and long‐term time series.

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Data‐Independent Acquisition Mass Spectrometry in Tumor Classification and Cancer Biomarker Research

Mass Spectrometry Reviews, EarlyView.
Abstract Cancer treatment is far from optimal also because current classification systems do not reflect the complex molecular status of the tumor and its phenotype in sufficient detail. To construct molecular tumor classifiers, omics tools provide complex molecular data reflecting many aspects from genotype to phenotype.
