A device for collection of gases in molten metals, the device comprising an immersion end having a gas collection body, a gas supply line opening at the immersion end, and a gas discharge line for gases penetrating the gas collection body, wherein the gas collection body has an end face arranged on the immersion end and on side walls of the gas collection body, and wherein at least a portion of the gas collection body has a gas impermeable layer.
A method for measuring a gas content in a molten metal, comprising the steps of introducing at least two different gases into the molten metal, the gases entering into a gas exchange with a gas contained in the molten metal, and then taking up and feeding the gases to a measurement device for evaluation, wherein each of the at least two gases has a respective carrier gas and optionally an admixture of one gas, whose percentage in the molten metal is to be determined, and wherein, in each case of gas introduction, the concentration of the admixed gas lies either below or above the concentration of the gas contained in the molten metal and to be measured.
