Although manual segmentation is considered to be the best mass boundary extraction method [ 10, 11], it is time-consuming.
This fraction is generally small but with caveats concerning mass range and extraction methods.
In summary, the CDC uses a solid-phase extraction method coupled to high-performance liquid chromatography tandem mass spectrometry.
The oil mass fraction in the sea mango seed was determined by Soxhlet extraction method.
PFAA assays deployed a protein precipitation extraction method with reverse phase high-performance liquid chromatography/tandem mass spectrometry.
PFAA assays used a protein precipitation extraction method with reverse-phase high-performance liquid chromatography/tandem mass spectrometry.
The seed cultures, fermentation medium, extraction method, and the liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) were performed as described for the 6-dEB extractions with the following modifications.
After mass spectrometer parameters optimized, chromatographic conditions such as mobile phase optimization, column optimization, and extraction method optimization was performed to obtain a fast and selective LC method.
The newly developed method (Nocardia Extraction Method at DCLC [NECLC]) based on ethanol-formic acid extraction (EFAE) improved mass spectra obtained from Nocardia specimens.
The Nocardia in-house database at Chiba University Hospital (NDCUH) was constructed using the new extraction method (NECLC) to process 192 Nocardia isolates stored at the MMRC and generate mass spectra as described in the " Methods" section.
