Abstract: The purpose of the present invention is to provide an injection apparatus and an injection method for a liquid sample for standard gas production, wherein the injection apparatus for injecting a liquid sample present in a liquid state at room temperature into a standard gas container has an improved structure that minimizes the area in which the liquid sample directly contacts the injection apparatus so as to prevent the problem in which the liquid sample is adsorbed into the injection apparatus. Furthermore, another purpose of the present invention is to provide an injection apparatus and an injection method for a liquid sample for standard gas production, in which a step of volatilizing the remaining liquid sample by heating is eliminated during the injection of the liquid sample, thereby preventing the apparatus from being damaged by heating to thereby improve the durability of the apparatus.

Abstract: A corrugated constant pressure cylinder apparatus having no micro leaks and its method of use. The internal pressure of the corrugated cylinder (b10) is maintained at a constant pressure so as to allow for transport or storage in a state without micro leaks. The corrugated constant pressure cylinder apparatus is able to keep substances that exist in gaseous or liquid form at room temperature such as mixed refrigerant gases, volatile organic compounds (VOC), hydrocarbon mixtures-in liquid form, or is able to keep the pressure constant even if the internal volume changes due to the contents inside the cylinder.

Abstract: The present invention relates to a corrugated constant pressure cylinder apparatus having no micro leaks and its method of use, and more specifically, a corrugated constant pressure cylinder apparatus having no micro leaks and its method of use where the internal pressure of the cylinder is maintained at a constant pressure so as to allow for transport or storage in a state without micro leaks. Therefore, this invention relates to a corrugated constant pressure cylinder apparatus having no micro leaks and its method of use where mixed refrigerant gases, volatile organic compounds (VOC), hydrocarbon mixtures, and other such substances that exist in gaseous or liquid form at room temperature are kept in a cylinder that maintains a constant internal pressure to keep the contents in liquid form, or is able to keep the pressure constant even if the internal volume changes due to the contents inside the cylinder.
