{"product_id":"mass-spectrometry-by-the-numbers-daniel-leo-sweeney-9798640748734","title":"Mass Spectrometry by the Numbers: Identifying Small Molecules from Accurate-Mass Fragmentation Data","description":"The most common approach for identifying unknown analytes using mass spectrometry combines fragmentation rules with circular reasoning - working backwards from the answer. 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.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Daniel Leo Sweeney\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 864074873X\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9798640748734\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 05\/10\/2020\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 176\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.09lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 10.00h x 7.99w x 0.46d","brand":"Daniel Leo Sweeney","offers":[{"title":"Paperback","offer_id":43942921109759,"sku":"9798640748734","price":39.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/products\/img_8817653b-65bd-4959-aeb8-8c9990e40dc3.jpg?v=1681495140","url":"https:\/\/www.whiterainbookhouse.com\/products\/mass-spectrometry-by-the-numbers-daniel-leo-sweeney-9798640748734","provider":"WR Book House","version":"1.0","type":"link"}
