Provided are methods and uses of polyoxyethylenepolyoxypropylene copolymers for treating bleeding and hemorrhage in animals, including human or veterinary subjects, and thus, treating hemostatic dysfunction, resulting from, for example, drug, disease-, trauma- or surgical-induced bleeding. According to an aspect of the invention, a peak position on a flight time scale and a total intensity are determined for each peak in the individual spectrum. A slit 18 is provided in the cylinder portion 12. Moreover, the manufacturing method of the touch panel with a shielding structure is a simple process, which reduces the manufacturing cost. The demister can operate at freezing temperature, is not dirt-sensitive and requires no maintenance.
