NMR sample holder Bruker MATCH tube holder system Bruker Multiple Adjustable Tube Clamp Holder Bruker MATCH tube holder system http://msi-ontology.sourceforge.net/ontology/NMR.owl#msi_400211 GROUP:<http://msi-ontology.sourceforge.net> NMR instrument PERSON:Daniel Schober The Bruker Multiple Adjustable Tube Clamp Holder MATCH system is a holder for 100 mm long NMR sample tubes with diameters ranging from micro tubes up to 5 mm NMR tubes. The MATCH insert fits into a standard 10 mm Bruker spinner and is suitable for all non-spinning applications.n The MATCH system provides an easy and cost efficient means of optimizing the signal-to-noise ratio of each sample. By matching the NMR tube diameter to the size of the sample, most of the sample can be placed in the active column of the NMR coil. This leads to an enhanced signal detection compared to diluting the same sample quantity in a larger tube. metadata complete
