Abstract

A mass spectrometer 10 includes: an insertion port 1 through which a sample plate 8 is to be inserted; a reading device 6 including: a light emitter 61 disposed to emit light in such a manner that the light falls onto the sample plate 8 inserted through the insertion port 1 ; and a light receiver 62 for receiving reflected by or transmitted through the sample plate 8 to read an identifier 80 provided on the sample plate 8 ; an analyzer 101 for performing a mass spectrometric analysis on a sample 9 placed on the sample plate 8 , to obtain analysis information of the sample 9 ; and a storage section 51 for storing identification information 800 of the sample plate 8 and the analysis information 100 of the sample 9 placed on the sample plate 8 , which are associated with each other, the identification information 800 being indicated by the identifier 80 read by the reading device 6 , and the analysis information 100 being obtained by the analyzer 101.

First claim

The invention claimed is:

1. A mass spectrometer comprising:
an insertion port through which a sample plate is to be inserted;
a reading device including: a light emitter disposed to emit light in such a manner the light falls onto the sample plate inserted through the insertion port; and a light receiver configured to receive light reflected by or transmitted through the sample plate to read an identifier provided on the sample plate;
an analyzer configured to perform a mass spectrometric analysis on a sample placed on the sample plate, to obtain analysis information of the sample; and
a storage section configured to store identification information of the sample plate and the analysis information of the sample placed on the sample plate while the identification information and the analysis information are associated with each other, the identification information being indicated by the identifier read by the reading device, and the analysis information being obtained by the analyzer,
wherein:
the light receiver is configured to receive light reflected from the sample plate, and
an identifier indicating an absence of the sample plate is disposed at a position opposite from the reading device across the sample plate inserted through the insertion port.

2. The mass spectrometer according to claim 1 , wherein:
the identifier is a barcode, and

the reading device is a barcode reader.
