Title:
生物物質の同定のための方法および装置
Document Type and Number:
Japanese Patent JP5671461
Kind Code:
B2
Abstract:
Biological material is detected in a sample using a MALDI-MS technique (Matrix Assisted Laser Desorption and Ionization-Mass Spectroscopy). A liquid comprising the sample and a MALDI matrix material is prepared and used to form a continuous stream of the liquid. The stream is separated into successive parts to form drops, which are launched into flight, or the stream is launched into flight and then separated into drops. Drop forming techniques may be used that are known from ink jet printers. Material from the drops is ionized while in flight. Mass spectra from the ionized material of respective drops are measured. Preferably, before the drops are formed the liquid is diluted to a level where the majority of drops at most one micro-organism is present per drop.
