Title: Mass spectrometer including a quadrupole mass analyser arrangement
Inventor: KALINITCHENKO IOURI
IPC: H01J49/06
Filed: 2001-08-17
Abstract: A mass spectrometer (10) having an ion optics system (32, 34, 36, 40, 42) in a first vacuum chamber (28) which diverts ions travelling in a first direction from a source (12, 16, 24) through an angle such that neutral particles and photons from the source continue in the first direction and are removed. The diverted ion beam (38) is then directed into a quadrupole mass analyser arrangement (52) in a second vacuum chamber (48) which comprises a configured, for example curved, set of fringe electrodes (56) followed by a linear mass analyser (54) and then an ion detector (46).  The configured fringe electrodes (56) again divert the ions prior to their passage into the linear quadrupole mass analyser (54) whereby additional neutral particles possibly created by passage of the ion beam through residual gas in the vacuum chambers (28, 48) are shielded from entering the linear mass analyser (54). The use of the configured set of fringe electrodes (56) in front of the linear mass analyser (54) has been found to substantially reduce background count rates, particularly for detection of isotypes of low atomic masses.

IPC: C12Q1/68
Filed: 2001-01-23
Abstract: L'invention concerne des techniques d'analyse homogène destinées à l'hybridation, la détection et l'évaluation d'acides nucléiques. Cette analyse consiste à obtenir des signaux depuis un échantillon d'essai, avant et pendant l'application d'une tension audit échantillon, et à établir une corrélation entre ces signaux qui indiquent l'affinité de liaison entre la sonde et la cible. Cette analyse permet de déterminer l'ampleur de la correspondance entre la sonde et la cible, la tension pouvant être étalonnée de manière à déstabiliser de façon significative toute hybridation à l'exception d'une hybridation parfaitement complémentaire. Les signaux dont l'amplitude correspond à une affinité de liaison peuvent être une conductance électrique et/ou une intensité de fluorescence. On mesure et on compare de préférence les deux paires de signaux de manière à accroître la fiabilité de l'analyse. Cette analyse permet de détecter une hybridation spécifique entre des sondes monocaténaires et des cibles bicaténaires non dénaturées pour former des triplex, ce qui rend superflue la dénaturation des cibles. Les techniques d'analyse de l'invention peuvent également s'appliquer à des complexes d'hybridation de duplex.
