Abstract
An analytical instrument for cellular analysis of cellular particles tagged with elemental tags, such as lanthanide-based elemental tags. The analytical instrument has a sample introduction system for generating a stream of particles from the sample. An inductively coupled plasma ionization system atomizes and ionizes particles in the stream as they are received. The instrument has an ion pretreatment system and a mass analyzer. The ion pretreatment system is adapted to transport ions generated by the ionization system to the mass analyzer. The ion pretreatment system can filter out low mass ions, such as using a high-pass mass filter or a bandpass mass filter, to allow the elemental tags to pass therethrough. The mass analyzer is adapted to measure the amount of at least one element in individual particles from the stream by performing mass analysis on the ions from the atomized particles. The instrument can be adapted to measure the amount of many different tags, for example at least five different tags, at the same time to facilitate multi-parametric analysis of cells and other particles.
