Question
### Mass Spectrometry Analysis The image displays a mass spectrum, which is a graphical representation of the relative intensity of ion signals as a function of the mass-to-charge ratio (m/z). Here’s a detailed explanation of the elements in the spectrum: #### Axes Description: - **Horizontal Axis (x-axis):** Represents the mass-to-charge ratio (m/z), ranging from 10 to 130. This axis is used to identify the ions based on their mass divided by their charge. - **Vertical Axis (y-axis):** Represents the relative intensity of detected ions. The scale ranges from 0 to 100, indicating the abundance of each ion compared to the most abundant ion, which is set to 100. #### Key Features of the Spectrum: - **Peak Labels:** The label "MS-1W-2851" indicates the sample or instrument used for generating this spectrum. - **Peaks and Intensity:** - Several notable peaks are present, particularly at m/z values around 40, 50, 80, 100, and 120. - The tallest peak, reaching an intensity of 100, is the base peak, representing the most abundant ion in the sample. - Smaller peaks at other m/z values signify ions with lesser abundance. #### Interpretation: - **Structural Analysis:** Each peak corresponds to a fragment of the molecule being analyzed. The m/z values can be used to deduce structural information about the compound. - **Identification:** By comparing with known spectra, the compound or mixture in the sample can be identified. This mass spectrum is an essential tool in analytical chemistry, frequently used for the identification and quantification of molecules in various fields, including biochemistry and environmental analysis.
