ABSTRACT:
An apparatus to collect contaminants from a known volume of fluid and to present the collected contaminants for analysis. The apparatus has a first container to receive the known volume of fluid and a second container to receive the fluid from the container. A contaminant trapping material is located between the two containers so that as the fluid passes from the first container to the second container it passes through the contaminant trapping material. The second container is connected to a vacuum generator used to create a vacuum in the second container. The apparatus also has means to recirculate the fluid from the second container back to the first container so that the fluid can pass through the contaminant trapping material a given number of times thereby insuring an adequate collection of contaminants. A method of collecting contaminants from a fluid and presenting the contaminants for analysis is also disclosed.
