Hadamard Transform Time-of-flight Mass Spectrometry
Hadamard transform TOF mass spectrometer is an instrument that can be used with a continuous ion source. Whereas traditional TOF MS analyzes one packet of ions at a time, waiting for the ions to reach the detector before introducing another ion packet, HT-TOFMS can analyze several ion packets simultaneously traveling in the flight tube. The ions packets are encoded by fast modulating the transmission of the ion beam in a manner based on a Hadamard matrix. The resulting spectra, however, can be deconvoluted based on knowledge of the encoding scheme.

Famous quotes containing the words transform and/or mass:
“The inspired scribbler always has the gift for gossip in our common usage ... he or she can always inspire the commonplace with an uncommon flavor, and transform trivialities by some original grace or sympathy or humor or affection.”
—Elizabeth Drew (1887–1965)
“In really hard times the rules of the game are altered. The inchoate mass begins to stir. It becomes potent, and when it strikes,... it strikes with incredible emphasis. Those are the rare occasions when a national will emerges from the scattered, specialized, or indifferent blocs of voters who ordinarily elect the politicians. Those are for good or evil the great occasions in a nation’s history.”
—Walter Lippmann (1889–1974)
