Provided herein is a fluid sensor, which includes a closed reaction unit in which reaction of a fluid sample takes place. The output of the second air compressor is used as a source of compressed air for an air suspension system of a motor vehicle andor to pressurize air inflatable articles. The clamping device has a pair of clamping rings that drive pairs of jaws. An air-heater is located upstream of the atomizer, and heats the airstream to a temperature of 110\xb0 C. The mixture is stable on prolonged storage at room temperature and promotes collagen regeneration in vivo in cases of bone trauma.
