1. Precursor ion scanning refers to monitoring for a specific loss from the precursor ion.
2. Precursor ion scanning refers to monitoring for a specific loss from the precursor ion.
3. Another key feature of SIFT-MS is the upstream mass quadrupole, which allows the use of multiple precursor ions.
4. From this spectrum, one can select a prominent product ion which can be the product ion for the chosen precursor ion.
5. Similar to the precursor ion scan, this method is useful in the selective identification of closely related compounds in a mixture.
6. It's difficult to find precursor ion in a sentence. 用precursor ion造句挺難的
7. Many commercial mass spectrometers are designed to expedite the execution of such routine sequences as selected reaction monitoring ( SRM ) and precursor ion scanning.
8. Note that precursor ion is synonymous with parent ion and product ion with daughter ion; however the use of these anthropomorphic terms is discouraged.
9. For a precursor ion scan, the product ion is selected in the second mass analyzer, and the precursor masses are scanned in the first mass analyzer.
10. When the precursor ion has an internal energy equal to E s ( AB + ), the rates of formation of AD + and AB + are equal.
11. Types of analysis include product ion scan, precursor ion scan, selected reaction monitoring ( SRM ) ( sometimes referred to as multiple reaction monitoring ( MRM ) ) and neutral loss scan.
12. By detecting a unique fragment ion, the precursor ion can be detected in the presence of other ions of the mass to charge ratio, reducing the background and increasing the limit of detection.
13. A recent technique for structure elucidation in mass spectrometry, called precursor ion fingerprinting, identifies individual pieces of structural information by conducting a search of the product-ion spectra of structurally characterized precursor ions.
