Analyzers for monitoring water quality in processor waste water streams require calibration with liquid standards. Traditional techniques for preparing these standards are cumbersome and often inadequate in their functions.
These problems are rectified with the use of permeation tubes to continuously add trace VOCs to a clean water stream to generate the standards on line. Permeation tubes have been used extensively and successfully in setting up gas standardsa, and this paper addresseses extending the method to liquid standards.
