Can High Performance Liquid Chromatography-Tandem Mass Spectrometry Be Used for Quantitative Analysis
Certainly. High performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) is a widely applied technique in bioanalytical research. In this method, high performance liquid chromatography (HPLC) serves to separate components from complex matrices, while the tandem mass spectrometer (MS/MS) is employed for the accurate detection and quantification of these separated analytes. By integrating the separation power of HPLC with the sensitivity and precision of mass spectrometry, HPLC-MS/MS enables quantitative analysis with high sensitivity, resolution, and accuracy.
Quantitative analysis using HPLC-MS/MS typically involves methods such as the internal standard method, external standard method, or calibration curve approach. In practical applications, HPLC-MS/MS is extensively utilized for the quantitative assessment of biological, environmental, and food-related samples, including the detection of pharmaceuticals, metabolites, environmental contaminants, pesticide residues, hormones, and biomarkers.
However, achieving accurate quantification requires careful consideration of multiple factors, including sample preparation protocols, chromatographic column selection, gradient elution conditions, and optimization of mass spectrometry parameters. Throughout experimental design and implementation, these variables must be rigorously controlled to ensure both the accuracy and the reliability of the quantitative results.
