Abstract:
Es wird eine Vorrichtung (110) zur Bestimmung mindestens einer optischen Eigenschaft einer Probe (112) vorgeschlagen. Die Vorrichtung (110) umfasst eine durchstimmbare Anregungslichtquelle (114; 410) zur Beaufschlagung der Probe (112) mit Anregungslicht (122). Die Vorrichtung (110) umfasst weiterhin einen Detektor (128, 130; 312) zur Detektion von von der Probe (112) ausgehendem Detektionslicht (132, 136; 314). Die Anregungslichtquelle (114; 410) umfasst ein Leuchtdiodenarray (1 14), welches zumindest teilweise als monolithisches Leuchtdiodenarray (114) ausgestaltet ist. Das monolithische Leuchtdiodenarray (114) umfasst mindestens drei Leuchtdioden (426) mit jeweils unterschiedlichem Emissionsspektrum.
Abstract:
The invention proposes an apparatus (110) for determining at least one optical property of a sample (112). The apparatus (110) comprises a tunable excitation light source (114; 410) for applying excitation light (122) to the sample (112). The apparatus (110) also comprises a detector (128, 130; 312) for detecting detection light (132, 136; 314) coming from the sample (112). The excitation light source (114; 410) comprises a light-emitting diode array (114) which is at least partially in the form of a monolithic light-emitting diode array (114). The monolithic light-emitting diode array (114) comprises at least three light-emitting diodes (426) each with a different emission spectrum.

Abstract:
Die Erfindung betrifft die Verwendung von Rylenderivaten der allgemeinen Formel (I) als Markierstoffe für Flüssigkeiten, wobei die Symbole und Indizes die in der Beschreibung angegebenen Bedeutungen haben.
Abstract:
The invention concerns the use, for marking mineral oils, of anthraquinones of formula (I) in which R is hydrogen, optionally substituted C1-C18 alkyl or optionally substituted phenyl and R is hydrogen or a group of the formula X-R in which X is oxygen or sulphur and R is optionally substituted C1-C18 alkyl or optionally substituted phenyl. The invention also concerns mineral oils marked with the above anthraquinones and dye mixtures containing an oil-soluble dye and one of the above anthraquinones.
Abstract:
The invention relates to a method for producing compounds of general formula (I) by converting the compound of general formula (II), where L, L' independently of one another are the same or different and represent Cl or OH, in the presence of a) chlorine compounds Cl-M2 R1 R2 R3, Cl-M3 R4 R5 R6, with the proviso that both L and L' are not OH at the same time, or b) hydroxy compounds HO-M2 R1 R2 R3, HO-M3 R4 R5 R6. The invention also relates to the use of compounds of general formula (I) as tracer substances for liquids and to methods for detecting tracer substances in liquids
