Active Sampling refers to the process of connecting sample collection media (i.e., thermal desorption tube) to a sampling train consisting of inert tubing and a sample pump operating at a know flow rate. Once activated, the sample pump draws air through the sample media, resulting in a know sample volume. Passive Sampling refers to the process of allowing sample collection media (i.e., thermal desorption tube) to passively diffuse air through the sample media without benefit of 'forced air'. This allows for longer potential sample periods without concern for overloading the sampling media. •

What is the difference between active and passive data dictionary?

The integrated data dictionary is called active if it is checked by DBMS every time a data base is accessed. It is always consistent with actual data base structure. It is automatically maintained by the system.The integrated data dictionary is called passive if it is not used in day to day database processing.

What is the use of taking passive monitoring when direct monitoring is there in industrial hygiene?

Direct monitoring of contaminants in the air is a long established process of directly measuring contaminants in place. This often requires bulky equipment and is suitable for measuring only one agent or family of agents. Passive monitoring may be direct reading, in which case it is a subset of direct monitoring that usually involves very light and small devices that can be easily worn by an individual Passive monitoring can also be a method for collecting a sample of air to be analyzed in a laboratory with equipment able to assess a broad range of different agents in the same sample. In this case, passive monitoring (more properly called passive sampling) collects the sample without requiring the use of a pump or other active device to draw the air into the sampling medium. All variations of monitoring and sampling methods have advantages and disadvantages. As a result, different methods will be better suited for different situations.

Are the sampling techniques the same for solid liquids and gases?

No, sampling techniques differ for solid, liquid, and gas samples. For solids, techniques like grab sampling or core sampling are commonly used. Liquids can be sampled using methods like grab sampling, pump sampling, or composite sampling. Gases are typically sampled using techniques like grab sampling, passive sampling, or active sampling using pumps or sorbent tubes.
