Abstract: Methods for specifying the layout of a MALDI sample plate are provided. In general, the methods involve creating a file containing sample plate layout parameters that describe the layout of a MALDI sample plate, and storing the file on a computer readable medium prior to placement of the MALDI sample plate into a MALDI ion source. In many embodiments, the file includes information about the size or shape of the sample plate, or information about the size, shape or position of a sample on the sample plate. In many embodiments, a MALDI sample plate is placed in a MALDI ion source and a stored layout file for the sample plate is accessed and used to position an area of the sample plate in a laser beam. The subject methods, kits and apparatus find use in a variety of different mass spectrometry applications.

Abstract: A mass spectrometer that includes a tray on the outer housing of the mass spectrometer for receiving a portable user interface. Each of the user interface and the tray has a transceiver port for transmitting and receiving electromagnetic wave radiation as infrared radiation. More specifically, the tray also includes a serial port connector and the portable user interface includes a receptor for receiving the serial port connected when the user interface is mounted on the tray.
