    • The invention relates to matrixes for ultraviolet matrix-assisted laser desorption-ionisation mass spectrometry made of the salt of an amine which reacts as a proton acceptor and an organic substance which reacts as a proton donator. Either the amine or the organic substance absorbs UV light. Said matrixes are characterised in that they represent an ionic liquid at room temperature and in that the amine is selected from the group which is made up of 3-aminoquinoline, pyridine, a primary amine whose N-Atom is bound to a phenyl radical or a straight or branched, saturated C1-C11-alkyl radical which can be substituted by an OH-group, a secondary and tertiary amine whose N-Atoms are bound to two or three radicals which can be the same or different and represent a straight or branched, saturated C1-C8-alkyl radical which can be substituted by an OH-group and a phenyl radical, imidazole and the C and/or N-alkylated imidazole derivatives and also characterised in that the organic substance is selected from the group which is made up of 2,5-dihydroxybenzoic acid and the isomers thereof, 2-hydroxy-5-methoxy-benzoic acid and the isomers thereof, picolinic-acid, 3-hydroxypicolinic acid, nicotinic acid, 5-chloro-2-mercapto-benzo-thiazole, 6-aza-2-thiothymine, 2',4',6'-trihydroxyacetophenone-monohydrate, 2',6'-di-hydroxyaceto-phenone, 9H-pyridol[3,4-b]indole, dithranole, trans-3-indolacrylic acid, osazones, ferulic acid, 2,5-dihydroxyacetophenone, 1-nitrocarbazole, 7-amino-4-methylcumarine, 2-(p-hdroxyphenylazo)-benzoic acid, 8-aminopyrene-2,3,4-trissulfonic acid, 2-[2E-3-(4-tert-butylphenyl)-2-methylprop-2-enylidene]malonitril (DCTB), 4-methoxy-3-hydroxycinnamic acid and 3,4-dihydroxycinnamic acid. Said liquid matrixes enable reproducible, error-free analysis values to be obtained. The combination of pure mass spectrometric analysis with additional knowledge of enzymatic reactions/modifications with the possible monitoring is also described.

    • The invention relates to an oligosaccharide mixture based on oligosaccharides produced from one or several animal milks and which are composed of two or more monosaccharide units. Said oligosaccharide mixture is characterized in that it comprises at least two oligosaccharide fractions which are each composed of at least two different oligosaccharides. The invention is further cahracterized in that lactose does not pertain thereto and the total spectrum of the oligosaccharides present in the oligosaccharide mixture differs from those present in animal milk or animal milks, wherefrom the oligosaccharide fractions are extracted and that a) if said oligosaccharides are extracted from only one animal milk, the proportion of neutral oligosaccharides to acidic oligosaccharides is 90 -60: 10 - 40 weight %, or b) if said oligosaccharides are extracted from at least two animal milks, the oligosaccharides extracted from two different animal milks each make up 10 weight % of the total amount of oligosaccharides present in the oligosaccharide mixture. The oligosaccharide mixture according to the invention approximates to human milk with respect to its positive properties and in particular its anti-infective activity.
