Dec 10, 2019 · Concern regarding the reproducibility of observations in life science research has emerged in recent years, particularly in view of unfavorable experiences with preclinical in vivo research. The use of cell-based systems has increasingly replaced in vivo research and the application of in vitro models enjoys an ever-growing popularity. To avoid repeating past mistakes, high standards of
Dec 14, 2021 · Reproducibility and research integrity are essential tenets of every scientific study and discovery. They serve as proof that an established and documented work can be verified, repeated, and reproduced. New knowledge in the biomedical science is built on the shoulders of established and proven principles. Thus, scientists must be able to trust and build on the knowledge of their colleagues
Jul 30, 2020 · Reproducible research is the bedrock of experimental science. To enable the deployment of large-scale proteomics, we assess the reproducibility of mass spectrometry (MS) over time and across
the selected control material(s). The resulting uncertainty has been obtained under reproducibility con-ditions and corresponds to the conventional analytical goals. Furthermore, the commutability of the control materials used determines whether the imprecision calculated from the control materials reflects the imprecision of measuring patient
The resulting uncertainty has been obtained under reproducibility conditions and corresponds to the conventional analytical goals. Furthermore, the commutability of the control materials used determines whether the imprecision calculated from the control materials reflects the imprecision of measuring patient samples.
However, non-specific binding and ionic interactions can also cause losses at higher concentrations. Such losses not only negatively impact the assay sensitivity, they also compromise the reproducibility, precision, and accuracy of the analysis. QuanRecovery Vials and Plates with MaxPeak HPS protect your sample, ensuring improved analytical
Aug 28, 2017 · This prevents vacuum formation / cavitation when aspirating the sample from the vial which can lead to irreproducible sample volumes being drawn into the autosampler syringe. The quality of the glass used in vial manufacture can be important when dealing with adsorptive compounds and this should be assessed on an application by application basis.
Apr 7, 2019 · While computational reproducibility in scientific research is generally expected when the original data and code are available, lack of ability to replicate a previous study -- or obtain consistent results looking at the same scientific question but with different data -- is more nuanced and occasionally can aid in the process of scientific discovery, says a new congressionally mandated report
Inter-comparison tests are usually used to evaluate the precision of test methods (precision tests) and to evaluate the performance of test laboratories (proficiency test). It is also a very powerful tool for maintaining and improving the laboratory competence. A successful inter-comparison test is based on a good organisation of the test
Analyzing diverse sample types for new compounds poses unique challenges. Scientists face the task of reporting lower concentration values while maintaining precision. This guide focuses on solid-phase extraction (SPE) as a powerful sample preparation technology, utilizing chromatographic packing material to address analytical challenges
Oct 1, 2020 · According to the National Academy of Sciences, reproducibility is obtaining consistent results using the same input data; computational steps, methods, and code; and conditions of analysis. 1 To be reproducible, results need to follow the same procedures and control what can be reasonably controlled. Reproducibility does not mean exactly
The autosampler component of a HPLC system is used to increase sample throughput, improve the precision of injections, and allow for unattended operation. Its main components are a needle or syringe, a metering device to measure sample volume, and a sample loop. There is also a valve used to control the hydraulic path of the eluent.
Feb 5, 2017 · Glass HPLC vials are ubiquitous in analytical laboratories and vendors have developed many varieties to meet the various needs of scientists. As such there may be multiple types of vials being used simultaneously in a single laboratory without much consideration as to which is best suited for analytical method development and validation.
Jul 9, 2021 · Mass-spectrometry-based proteomics is a powerful approach for discovering disease biomarkers. This tutorial provides advice on the study design, including cohort selection, evaluating statistical
