Multiple aspects need to be considered when building a protein-based mass spectrometric assay such as the selection of signature peptide, calibration matrix and the choice of internal standard ...

WE have recently analysed a sample of medical oxygen by mass spectrometry, and found that the level of carbon monoxide, approximately 1 per cent, far exceeded the toxic level for humans. Subsequent ...

Commercially available mass spectrometers can reliably detect the SARS-CoV-2 coronavirus. In the journal "Clinical proteomics" researchers from the Martin Luther University Halle-Wittenberg (MLU) ...

Elemental analyzers are also frequently called combustion analyzers because the combustion of the sample is an essential step of the analysis process. ELTRA analyzers utilize various types of furnaces ...

Since its discovery over 50 years ago, the biological aspects of insulin-like growth factor-1 (IGF-1) have been determined to be extensive. Ranging from cell proliferation, cell differentiation and ...

Neutron activation analysis is a cutting-edge analytical technique that identifies elements and determines their concentration in numerous different applications. With accurate, fast gamma ...
