Mass Spectrometric Analysis TRIZ Cases
- Multiplex Mass Spectrometry for Separate Vitamin D Metabolite Quantification
Isotopic Cookson derivatization lets one mass spectrometric assay separately quantify 25OHD2 and 25OHD3 across multiplex samples.
- MS2 Reporter-Ion Quantitation With Ratio Distortion Correction
Computational signal decomposition corrects distorted isobaric reporter-ion ratios in MS2, improving peptide quantitation without slower MS3 scans.
- MS2 Reporter-Ion Quantitation With Interference Signal Decomposition
Computational signal decomposition separates peptide and interfering ion contributions to correct MS2 reporter-ion ratios without MS3.
- IROA Metabolomics Workflow Using Symmetrical Isotope Peaks
Symmetrical IROA isotope peaks enable reproducible metabolite identification and quantitation across instruments and over time.
- IROA Metabolomics Workflow for Drift-Resistant Compound Quantitation
Standardized isotopic Matrix peaks correct instrument and chromatographic drift, enabling reproducible metabolite identification and quantitation.
