The large photoabsorption cross sections of peptides at 193 nm and the resulting high internal energy deposition can generate abundant fragment ions and achieve high sequence coverage. The excellent fragmentation performance offered by 193 nm UVPD of peptides with its high sequence coverage and lack...
Because of its advantages of short analytical time, less organic solvent consumption, and easy separation of adsorbents, MSPE has attracted much attention. The key to MSPE is the preparation of highly selective magnetic adsorbents. Covalent organic frameworks have the advantages of large surface area,...
and its respective isomeric forms. Using this approach in combination with IDMS analysis, more consistent, accurate, and reproducible measurement results for the four tetracyclines in chicken meat were acquired. LC-MS/MS conditions and sample preparation processes were comprehensively optimized to minimize...

parameter selection are presented and critiqued, and their notation is unified for clarity. By rendering LLC and its alternative operating modes more accessible to current and prospective users, it is hoped to help expand the application of this technology and support the achievement of its full ...
The types and intensities of smells emitted by odorous sub- stances are determined by their molecular weight, structure, and many other variables1,2. Following the example of other countries who have put effort into regulating the emission of malodorous substances, Korea established the offensive ...

Abstract ( 422 ) HTML ( 15 ) PDF (944KB) ( 191 ) 2-Acetyl-1-pyrroline (2-AP) has been identified as the characteristic aroma component of fragrant rice, and its concentration determines the quality and price of the rice. However, obtaining accurate assay results with modern analytical ...
In combination with elemental analysis, gas chromatography, liquid chromatography, etc., IRMS is widely used in food safety, environmental protection, forensic science, and other fields. IRMS also plays an important role in the comparison and trace of explosives. Since its application to distinguish ...
