Mass Spectrometer 🔬🧪
The Mass Spectrometer stands as an indispensable analytical tool in medical and pharmaceutical research, owing to its unparalleled sensitivity and selectivity. The instrument works by ionizing molecules, separating them based on their mass-to-charge ratio ($m/z$), and measuring the abundance of each ion. In diagnostics, this technology is paramount for identifying and quantifying thousands of biomolecules, including proteins, peptides, and metabolites, within clinical samples like blood or urine. This capability is foundational to metabolomics, which maps altered biochemical pathways in disease states, and proteomics, which analyzes the entire protein profile of a sample.
The instrument's utility is expanding rapidly from complex biomarker discovery in the research setting to routine clinical applications, such as therapeutic drug monitoring, newborn screening for metabolic disorders, and toxicology. Despite its power, a key challenge for broader adoption is the need for greater standardization in sample handling and analytical procedures to ensure inter-laboratory reproducibility. Addressing these standardization…
