The sampling apparatus includes an automatic sampling device, and a multi-sorbent trap connected to the automatic sampling device sample for adsorbing the volatile organic compound at room temperature, wherein the volatile organic compound includes a polar and a non-polar compounds.

Abstract: A real time monitoring system for automatically monitoring a gaseous pollution sample in environment. The system includes a sample preprocess apparatus (SPA) for immediately processing the gaseous pollution sample at room temperature, wherein the gaseous pollution sample includes a polar and a non-polar compounds, a sample separation apparatus for separating the gaseous pollution sample, a sample analysis apparatus for analyzing a target compound of the gaseous pollution sample, and a data processing device for automatically processing an analyzed data of the target compound to achieve the real time monitoring system.

Abstract: The present invention is related to a method for generating .sup.90 Y from .sup.90 Sr which includes steps of a) providing a crown-ether bonded silica gel, and b) having .sup.90 Sr stay with the crown-ether silica gel for a period of time. The present invention is also related to a .sup.90 Sr/.sup.90 Y generator for implementing the method, which includes a .sup.90 Sr/.sup.90 Y converting device including the crown-ether bonded silica gel for adsorbing .sup.90 Sr and converting .sup.90 Sr into .sup.90 Y, and an eluting device forcing an eluant to elute the .sup.90 Sr/.sup.90 Y converting device to obtain .sup.90 Y. The generator according to the present invention has advantages of simplicity, reusability, high yield and low cost. The obtained .sup.90 Y by the present method possesses high purity so that it is suitable for nuclear medicine use.
