Which of the following statements are correct for a successful mass sp...
Explanation:
Successful mass spectroscopic analysis requires several key factors to be in place. Let's analyze each statement to understand why option 'D' is the correct answer.
Statement 1: Each component must exhibit at least one peak that differs markedly from the others
In mass spectroscopy, different components in a sample are separated based on their mass-to-charge ratios (m/z). Each component will produce a peak on the mass spectrum corresponding to its unique m/z value. For a successful analysis, it is important that each component has a distinct peak that can be differentiated from other peaks. This allows for accurate identification and quantification of individual components in the sample.
Statement 2: The contribution of each component to a peak must be linearly additive
Mass spectroscopy measures the abundance of ions at different m/z values. It is assumed that the abundance of ions is directly proportional to the concentration of the corresponding component in the sample. Therefore, the contribution of each component to a peak should be linearly additive. This linearity allows for accurate quantification of components based on the intensity of their peaks.
Statement 3: The sensitivity must be reproducible to 1% relative
Sensitivity refers to the ability of the mass spectrometer to detect and measure low concentrations of analytes. Reproducibility of sensitivity is crucial to ensure consistent and reliable results. A relative reproducibility of 1% means that the measured values should not deviate by more than 1% from the true values. This level of reproducibility ensures the accuracy and precision of the analysis.
Statement 4: Suitable standards must be available for calibration
To accurately quantify the components in a sample, calibration is necessary. Calibration involves analyzing known standards with known concentrations to establish a relationship between the intensity of the peaks and the concentration. Suitable standards are essential for calibration, as they provide reference points for accurate quantification.
Conclusion:
All four statements are correct for a successful mass spectroscopic analysis. Each component should have distinct peaks, the contribution of each component should be linearly additive, the sensitivity should be reproducible to 1% relative, and suitable standards must be available for calibration. Therefore, the correct answer is option 'D'.
