A mass spectrometry apparatus, including a mass spectrometer and a sample plate. The mass spectrometer includes: a sample plate holder configured to hold a sample plate in an engaged position. The mass spectrometer is configured to perform a mass spectrometric analysis of a sample only when the sample is located on a sample plate that is held in the engaged position by the sample plate holder. The mass spectrometer includes one or more engagement features configured to engage with a sample plate so as to prevent the sample plate from being held in the engaged position by the sample plate holder unless the sample plate includes one or more engagement features configured to limit use of the sample plate to a specific analytical technique or a range of analytical techniques to be performed using the mass spectrometer. The sample plate is configured for use in the specific analytical technique or range of analytical techniques, wherein the sample plate includes the one or more engagement features configured to limit use of the sample plate to the specific analytical technique or range of analytical techniques.

Mass spectrometry apparatus

The present invention provides an ion selector gate having a first deflection zoneand a second deflection zonespaced from the first deflection zone, wherein in use, a single low voltage trigger pulse generated by timing electronics with a width in time equal to or proportional to the width of the gate pulse Tand at a position in time that the ion gate is required to be open to allow through ions of the correct nominal mass. The trigger pulse may go through an inverterand then to two high voltage pulsersand. The high voltage pulsers each produce simultaneously a signal that switches to ground and back on again from the same amplitude high voltage but the opposite polarity. The outputs of the high voltage pulsers are connected to interleaved wires of both ion gates. Thus, the high voltage pulsers are applied simultaneously to both ion gates.
