LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis. Find the best LC-MS equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.NanoLCNano LC is a nano scale liquid chromatography technique typically used for proteomic applications. The nano refers to the very low flow rate of the mobile phase in the system. The advantage of nanoLC is its high sensitivity. Often the system is integrated with a mass spectrometer in nano LC-MS or nano LC-MS/MS. When using nanoLC equipment consider column choice, software and accurate and precise flow rate control.ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.NanotechnologyLC-MSLiquid Chromatography-Mass Spectrometry (LCMS) is a powerful analytical technique that combines the separation power of liquid chromatography with the detection capabilities of mass spectrometry. It is widely used for qualitative and quantitative analysis of complex mixtures in pharmaceuticals, proteomics, and environmental studies.
