This product is for research use only. Do not administer it to human.

Q-TOF (quadrupole-time-of-flight) mass spectrometers are used in proteomics/metabolomics research, etc. because this instrument allows simultaneous identification/determination of unknown substances in complex samples.
This is a solvent in which inpurities interfering ESI ionization using a high-sensitivity/high-resolution Q-TOF mass spectrometer are reduced as much as can be. This product, tested by ultimate high-performance liquid chromatography (UHPLC), is compatible with high-sensitivity LC/MS.
White spots, seen in the cap occasionally, do not affect the quality because they are air bubbles made in the cap formation.
