Adjustments to the concentration of water and salts within the urine takes place mainly in the distal parts of the tubules and in the collecting tubules, by altering the permeability of the membranes of cells lining the nephron walls. These changes are brought upon to two hormones, ADH and aldosterone.
Use for Colorimetric and Turbidimetric Determinations. These photometric colorimeters use specific light filters to give readings on a unique KlettTM scale. The readings are directly proportional to the concentration or optical density of a solution, in accordance with Beers Law.
A colorimeter is commonly used to test the concentration of disinfectants like chlorine used in drinking water, pool and spa applications, industrial wastewater plants, paper manufacturing, and other industries.A colorimeter can be a single-parameter, multi-parameter. colorimeter is commonly used to test the concentration of disinfectants like chlorine used in drinking water, pool and spa applications, industrial wastewater plants, paper manufacturing, and other industries.
