But you no longer have to work backwards from the answer. Using this new Rational Numbers Excel Add-In described in this book and accurate-mass fragmentation data, the mathematical and graphical powers of Excel can be directly applied to analyzing mass spectral data obtained using LCMS. This Excel Add-In is designed to help identify small molecules from less-than-perfect mass spectral data. All data must be accurate mass fragmentation data with a minimum accuracy of +\/- 5 mDa, which has become common recently. This book is not concerned with the technical or experimental aspects of ion formation, mass selection or mass measurement; it deals primarily with the analysis of accurate mass fragmentation data of to identify small molecules . In this book, there are no fragmentation rules, chemical drawings of hypothetical fragment ions, or quantum mechanics. This book is basically the author's perspective about a new tool that can help chemists, not just mass spectrometrists, to identify analytes quickly from LCMS data generated using electrospray ionization.\u003c\/p\u003e","brand":"Independently Published","offers":[{"title":"Paperback","offer_id":45569907785879,"sku":"9798640748734","price":3494.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9798640748734.webp?v=1767936704","url":"https:\/\/atlanticbooks.com\/products\/mass-spectrometry-by-the-numbers-identifying-small-molecules-from-accurate-mass-fragmentation-data-9798640748734","provider":"Atlantic Books","version":"1.0","type":"link"}
