Whereas conventional mass spectrometers have very limited
sensitivity for molecular masses beyond 15’000 Dalton our new,
patented macromizer has unchallenged sensitivity for macromolecular
analyses up to megadaltons.
The principle of this innovation is based on cryogenic STJ
(Superconductive Tunneling Junction) detectors that have mass independent
single molecule detection sensitivity.
Such new mass spectrometers are needed in the fast growing fields of
biotechnology, genomics, proteomics and life science analytics for
identification, quantification & analysis of macro molecules.
The first instrument was delivered to our beta test site on March 2003.
