Can High Performance Liquid Chromatography-Tandem Mass Spectrometry Be Quantitative
High Performance Liquid Chromatography-Tandem Mass Spectrometry (HPLC-MS/MS) is a powerful and widely employed analytical technique in the field of bioanalysis. In HPLC-MS/MS, High Performance Liquid Chromatography (HPLC) serves to separate components within complex matrices, while tandem mass spectrometry (MS/MS) enables precise detection and quantification of the separated analytes. By integrating the separation efficiency of HPLC with the high sensitivity and specificity of MS/MS, this technique facilitates highly sensitive, high-resolution, and accurate quantitative analysis.
Quantitative analysis using HPLC-MS/MS typically involves approaches such as the internal standard method, external standard method, or calibration curve method. In practical applications, HPLC-MS/MS is extensively utilized for quantitative assessment in areas including biological matrices, environmental monitoring, and food safety. It supports the detection and quantification of a broad range of analytes, including pharmaceutical compounds, metabolites, environmental contaminants, pesticide residues, hormones, and biomarkers.
Nevertheless, achieving accurate quantitative results with HPLC-MS/MS requires careful consideration of various experimental parameters, including sample preparation protocols, chromatographic column selection, gradient elution conditions, and mass spectrometry parameter optimization. To ensure the precision and reliability of the quantitative outcomes, these variables must be rigorously controlled during both method development and routine analysis.
