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\u003cdiv\u003e\n\u003cstrong\u003eNumber of Pages:\u003c\/strong\u003e 176\u003c\/div\u003e\u003cdiv\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.46 x 10 x 7.99 IN\u003c\/div\u003e\u003cdiv\u003e\n\u003cstrong\u003ePublication Date:\u003c\/strong\u003e May 10, 2020\u003c\/div\u003e","brand":"Books by splitShops","offers":[{"title":"Default Title","offer_id":42102747070599,"sku":"9798640748734","price":53.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/2623\/2711\/files\/9b9aa690497c5b2155697469b6c4c35e.webp?v=1732406917","url":"https:\/\/booksby.splitshops.com\/products\/mass-spectrometry-by-the-numbers-identifying-small-molecules-from-accurate-mass-fragmentation-data-paperback","provider":"Books by splitShops","version":"1.0","type":"link"}
