The experimental dataset includes mass-to-charge ratio (m\/z), retention time (RT), tandem MS (MS\/MS) spectra, and traveling wave ion mobility spectrometry (TWIMS)-derived Collisional Cross Section (TWCCSN2) values. Notably, 263 TWCCSN2 values were reported for the first time, with over 70% corresponding to VLMs. The TWCCSN2 values exhibited high repeatability, with inter-day variations of &lt;1% relative standard deviation (RSD). Moreover, the method demonstrated excellent TWCCSN2 accuracy, with a Collisional Cross Section (CCS) difference (DCCS) within \u00b12% of reported drift tube ion mobility spectrometry (DTIMS) and TWIMS CCS values. Significantly, the complexity of the urine matrix did not compromise the method&#8217;s precision. Utilizing the Metabolomics Standards Initiative guidelines, we identified 55 urinary metabolites with a confidence level of 1, of which 53 (96%) were VLMs. The enhanced confidence in metabolite identification was attributed to the inclusion of TWCCSN2 values, significantly increasing the number of confirmed compounds.<\/p>\n<p>This research marks a significant advancement in analytical techniques, paving the way for improved metabolite measurement and identification in human urine samples.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-49624\" src=\"https:\/\/www2.si.mahidol.ac.th\/en\/wp-content\/uploads\/2024\/05\/MSB-Analysis-Techniques_2567_WB-1280x728.png\" alt=\"\" width=\"1280\" height=\"728\" srcset=\"https:\/\/www2.si.mahidol.ac.th\/en\/wp-content\/uploads\/2024\/05\/MSB-Analysis-Techniques_2567_WB-1280x728.png 1280w, https:\/\/www2.si.mahidol.ac.th\/en\/wp-content\/uploads\/2024\/05\/MSB-Analysis-Techniques_2567_WB-768x437.png 768w, https:\/\/www2.si.mahidol.ac.th\/en\/wp-content\/uploads\/2024\/05\/MSB-Analysis-Techniques_2567_WB-1536x874.png 1536w, https:\/\/www2.si.mahidol.ac.th\/en\/wp-content\/uploads\/2024\/05\/MSB-Analysis-Techniques_2567_WB.png 1920w\" sizes=\"auto, (max-width: 1280px) 100vw, 1280px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We are thrilled to share the publication of groundbreaking research by the esteemed Assoc.
