WebbAs a general recommendation, the water content in an eluent used in LC-MS should be set to 5 to 80% in order to work trouble-free and with a stable spray. If the water content is below 5%, buffers may precipitate in the eluent and the HPLC system. A countermeasure can be the use of a suitable organic solvent or a decrease of buffer ...

WebbThe surface plasmonic resonance, surface wettability, and related mechanical nanohardness and of face-centered-cubic (fcc) chromium nitride (CrN) films have been successfully manipulated via the simple method of tuning nitrogen-containing gas with different nitrogen-to-argon ratios, varying from 3.5 (N35), to 4.0 (N40), to 4.5 (N45), … WebbIn general, purity increases as the number of clusters increases. For instance, if we have a model that groups each observation in a separate cluster, the purity becomes one. For this very reason, purity cannot be used as a trade off between the number of clusters and … business accounting consulting firms
