Magnesium (Mg)
| Engelsk navn: | Magnesium | |
| Analyseinstrument: | Advia®1800 | |
| Reagensprodusent: | Siemens Medical Solutions Diagnostics | |
| Analyseprinsipp: | Xylidyl Blue Magnesium ions reacts with xylidyl blue in an alkaline medium to form a water soluble purple-red chelate. The increase in absorbance of xylidyl blue at 505 nm is proportional to the concentration of magnesium in the sample. (Metoden tatt i bruk: 1/7-01) | |
