ENERGY EXPENDITURE USING DOUBLY LABELLED WATER. Iso-Analytical provides a full range of analytical services for customers wishing to determine Energy Expenditure using doubly labelled water. The Doubly Labelled Water (DLW) method uses the natural occurring stable isotopes of water (D2O and H218O) to assess energy expenditure, body composition and water flux in humans and animals.
In less dense liquids the hydrometer will float lower, while in more dense liquids it will float higher. Since water is the standard by which other liquids are measured, the mark for water is probably labeled as 1.000; hence, the specific gravity of water at about 4Â°C is 1.000. Hydrometers have many uses, not the least being to measure the salinity of water, or even urine, for science classes in schools.
