  • Description

    LC/MS/MS is a simultaneously provide excellent selectivity spectral measurement range analysis speed quantitative accuracy and precise mass spectrometry at an exceptional level of sensitivity. This technology provides information suitable for various applications such as peptide mapping, protein intact mass analysis, metabolite identification, etc., enabling rapid and correct qualitative and quantitative analysis.
