Can ct scan detect ms lesions? Because CT scans typically do not help to identify the more chronic lesions, the tumefactive MS lesion may appear as a solitary enhancing mass, which leads to neurosurgical intervention. Fortunately, this situation is relatively uncommon.
How do you test for fluoride in water? To perform the test, the user must mix a 4 ml water sample and 1 ml zirconium xylenol orange reagent. The color changes from pink to yellow depends on the fluoride concentration in the sample. By comparing the color produced with the color chart, the fluoride content in the water can be quantified.
How do you test for fluorine? For fluorine testing, the appropriate size solid sample is weighed and inserted into a micro bomb. The bomb is then charged with the appropriate reagents to completely digest the fluorine compound. The apparatus is clamped shut and heated in a flame for 60 seconds. The contents are washed out and diluted.
Why do we test for fluoride in water? The levels are usually lower in estuarine areas due to dilution by fresh water, unless fluoride pollution is occurring upstream. Measuring fluoride in water is important as fluoride is toxic to humans and aquatic life.
