  • Patent number: 7803273
    Abstract: A filter comprises at least one filtration unit with a filtration passage having an inlet and an outlet, wherein the filtration unit includes at least one groove formed in an inlet side surface of the filtration unit, said at least one groove extending to the inlet and dimensioned to hold back substances which may clog the filtration passage, by means of upper edges of said at least one groove. According to the present invention, by forming at least one groove in an inlet side surface of the filtration unit, the filtration passages of the filter can be effectively prevented from being clogged.

  • Patent number: 6799121
    Abstract: A strategy for semiautomatic sequencing of argentinated (silver-containing) oligopeptides is described. The method of sequencing described is based on a search algorithm that identifies a triplet peak relationship in a product ion spectrum of the [M+Ag]+ ion of an oligopeptide. The ions that constitute a triplet are [bn+OH+Ag]+, [bn−H+Ag]+, and [an−H+Ag]+, which are separated by 18 and 28 m/z units, respectively. The difference in the m/z values of adjacent triplets identifies the residue that is “cleaved”. Observation of the [yn+H+Ag]+ ion containing the cleaved residue confirms the assignment.
