HPLC Basics | Thermo Fisher Scientific - US
Liquid chromatography-mass spectrometry (LC-MS) utilizes a mass spectrometer instead of the traditional optical detector like a UV-Vis detector. Here the mass-to-charge ratio of the analyte is measured instead of optical properties.
HPLC vs. LC-MS/MS - What's the Difference? - This vs. That
LC-MS/MS is particularly useful for analyzing complex samples, such as biological fluids, as it can provide highly sensitive and selective measurements. Overall, while HPLC is a powerful separation technique, LC-MS/MS offers the added advantage of molecular identification and structural elucidation.
Principles of LC-MS analysis • HPLC flow rate 1-2 mL/min, 4.6 mm ID column, 3-or 5-µm silica-based particles, 5-30 µL injection. • Capillary LC flow rate 200 µL/min, 1 mm ID column, 1.5- to 3-µm silica-based particles, 1-5 µL injection • Nano LC flow rate 200 nL/min, 0.1 mm ID column, 3-µm silica-based particles, 0.1-2 µL injection
