WebAn increasingly attractive strategy is multiplex isotope labeling, which significantly improves the accuracy, precision and throughput of quantitative proteomics in the data‐dependent acquisition mode. Isotope labeling‐based approaches can be classified into MS1‐based and MS2‐based quantification. WebTwo pairs of stable isotope labeling (SIL) agents, (4-carboxyphenyl)trimethylammonium iodide (d 0-CPTA) and its deuterated counterpart d 3-CPTA, 1-methyl-nicotinamide iodide (d 0-MNA) and its deuterated counterpart d 3-MNA, were designed and synthesized.Their mass spectrometry (MS) sensitivity enhancement effect was studied and compared with …

WebNo isotope fractionation Thanks to the fast and complete conversion process of the high-temperature combustion, no isotope fractionation is observed. Period. This results in precise, high-quality data that can be trusted to represent the actual isotope ratios of a wide variety of samples. The iso CHROM LC can be connected to any HPLC system WebEffective separation of lithium isotopes (6 Li and 7 Li) is of great importance for the development of nuclear energy.Crown ethers (CEs) are widely used and reported separation systems, but the distribution coefficient of Li (D Li) is relatively low by CEs (D Li, 10 − 2 –10 −5 Li) is relatively low by CEs (D Li, 10 − 2 –10 −5 Web@article{osti_5697889, title = {Fractionation of lithium isotopes in cation-exchange chromatography}, author = {Oi, Takao and Kawada, Kazuhiko and Kakihana, Hidetake … some old people are troubled by the fear
