6 Principle of a Mass Spectrometer (MS) Mass Spectrometer A high voltage is applied to the column eluate, and it is atomized by nitrogen gas. The charged droplets gradually become smaller, and ion evaporation occurs. As the ions pass through the mass separator, they are separated according to mass. In the detector, the quantity of ions is detected as a current value. Positive ion (protonated molecule) Proton added Proton removed Negative ion (deprotonated molecule) Proton (hydrogen ion) イオン化したい化合物の分子 Separated in a column Mixed sample injected Introduced into MS in order from component with lowest retention Mobile phase Column eluate Ion focusing unit Mass separator Detector Ion source Atmospheric pressure region Vacuum region

LAAN-E-LM If peak elution is late: If an impurity coincides with the target component: Mobile phase preparation errors Fluctuations in peak retention times Peak misidentification AB AB If an impurity coincides with the target component: Changes in area value Incorrect quantitation Risks Associated with LC Detectors
LAAN-E-LM The greatest merit in using an MS instrument as an LC detector: In addition to retention times, mass information for each peak can be obtained simply at the same time. m/z 264 m/z 278 m/z 267 m/z 281 The peaks (including those that cannot be separated by time) can be separated using mass information. This reduces the risk of qualitative and quantitative errors. Merits of MS Detectors Mass information is a powerful tool for reducing the risks associated with LC analysis, such as the following: Peak identification (i.e., qualitative) errors Quantitative errors due to the elution of unpredicted impurities
LAAN-E-LM Features of the LCMS-2020
LAAN-E-LM With the introduction of the Prominence Ultrafast LC (UFLC), which offers the ultimate level of speed, superior reproducibility, and comprehensive expandability, ultrafast LC analysis is no utilized in a variety of new fields min. HPLC min.2.0 UFLC Shimadzu's Ultrafast LC Lineup Prominence UFLC: Greatly reduces analysis time without sacrificing separation. Prominence UFLCXR:Achieves greater separation while maintaining ultrahigh speed. From HPLC to UFLC, Then to UFLC-MS
LAAN-E-LM A mass spectrometer responding to the performance of UFLC: LCMS-2020 What makes an MS instrument suitable for UFLC? The ability to acquire data at high speed without sacrificing data quality is required! The three things that enable ultrafast analysis: The ability to perform scan measurement at high speed UFscanning The ability to switch between positive and negative ion measurement at high speed UFswitching High sensitivity in high-speed measurement UFsensitivity UFLC-MS
