摘要:
The present disclosure concerns a measuring probe (10) for non-invasive in vivo measurement of blood analytes (33) by Raman spectroscopy. The measuring probe (10) comprises a housing (20) having a skin engaging surface (21). The housing (20) comprises a first optical system (1, 3, 4) arranged for providing source light (11) to the skin engaging surface (21) for penetrating a subject's skin (31) by said source light (11) for interacting with the blood analytes (33). The housing (20) further comprises a second optical system (5, 6, 2) arranged for capturing scattered Raman light (12) from the blood analytes (33) for measurement of the blood analytes (33). The first optical system (1, 3, 4) is arranged for providing the source light (11) as a collimated beam (1c) onto the skin (31).

摘要:
Method for detecting one or more elements of the periodic system of elements, in particular one or more metal ions, in a fluid using LASER induced breakdown spectroscopy (LIBS), the method comprising (a) contacting a sample of the fluid with a surface comprising chelating groups bound to a surface of a solid element-extraction product the chelating group having specific binding affinity for one or more elements to be detected; (b) allowing said one or one or more elements present in the fluid to chelate with the chelating groups; (c) removing the fluid from the solid element-extraction product whilst the one or more elements chelated to the chelating groups remain chelated; thereafter (d) using the solid element-extraction product for a detection specimen, whilst the chelated element or elements remain chelated; (e) and subjecting the detection specimen to LIBS, under conditions that allow detection of the one or more elements chelated to the chelating groups.
摘要:
Methods are provided for determining whether a chicken egg, or a chicken egg pool, belongs to a class of organic chicken eggs. The yolk scyllo-inositol and myo-inositol concentrations, or concentration-related signals or values, are measured and the ratio between the scyllo-inositol concentration or concentration-related signal or value and the myo-inositol concentration or concentration-related signal or value is determined.
摘要:
The invention provides novel markers for classifying the housing systems of eggs. Classification methods as well as kits of parts using these novel markers are also herewith provided.
