has proper occurrent part nanoelectrospray ionisation mass spectrometry high-performance liquid chromatography-nanoelectrospray ionisation mass spectrometry CHMO:0000489 HPLC-nanoESI HPLC-nano-HPLC A method where the sample mixture is first separated by high-performance liquid chromatography before being ionised by forcing a solution (usually in an organic solvent) of the sample through a small heated capillary (at a flow rate of nL min1) into an electric field to produce a very fine mist of charged droplets. The ions are then characterised by their mass-to-charge ratio and relative abundance. high performance liquid chromatography-nanoelectrospray ionization mass spectroscopy high performance liquid chromatography-nanoelectrospray ionization mass spectrometry high performance liquid chromatography-nanoelectrospray ionisation mass spectroscopy liquid chromatography-electrospray ionisation mass spectrometry high-performance liquid chromatography-mass spectrometry high-performance liquid chromatography
