Title:
MASS SPECTROMETRY TECHNIQUE
Document Type and Number:
WIPO Patent Application WO/2018/012220
Kind Code:
A1
Abstract:
Provided is a mass spectrometry technique in which a sample is heated and vaporized inside a mass spectrometer, the technique being capable of providing an accurate analytical measurement of a sample containing low boiling point components. According to this technique, a vaporized gas obtained by heating and vaporizing a sample in a depressurized sample chamber is ionized, and detection intensity is measured with respect to m/z value. This technique is characterized in that the vaporized gas is heated to its vaporization temperature or higher and then released into the sample chamber.
