3.5Setting Up the Intake Line and Strainer
For each sampling location, the intake line should be as short as practical, and be free of any sharp bends, coils, or loops. Install the intake line with a downward slope from the sampler to the sample source because:
•This will assure the complete drainage of the intake line when it is air- purged before and after each sample, and will help to prevent cross- contamination of the individual samples.
•Complete drainage is important in freezing conditions, as any liquid slugs that remain could freeze and plug the line.
Place the sample intake and strainer in the mainstream of the sampling source, in an area of turbulent and
Also, take in account the vertical location of the intake. A position too near the surface may yield excess lighter materials, while a position too near the bottom may yield excess heavy materials. The constituents of interest must be considered when positioning the intake strainer.
