Unsure what ionization technique to choose?
Mass spectrometers require ionization for measurement. There are numerous ionization methods employed in MS, here is a guide that will help you better understand the possible options. Electrospray ionization (ESI) is used whenever possible(ESI), but if ESI was unable to generate satisfactory results, other techniques can be carried out. When in doubt, please ask . Also, please visit JEOL Analytical Instruments website if you would like additional information on different types of ionization methods. • • Do I need high resolution? High resolution is generally required for journal publications (≤ 1000 m/z). If you would like to have high resolution performed, on the submission sheets, please check the appropriate box for “High Res if Low Res Pass”. Please note that high resolution analysis will require a longer turnaround time and cost more than low resolution analysis. • Can I run all my samples by Open Access? The OA LC/MS instrument is equipped with an ESI ionization source. Your samp
