Abstract
T o ensure drinking water quality, continuously monitoring the volatile organic compounds in the source water and the treated water is very important for any water treatment plant. On-line, real time information will be crucial to the engineers and operators. For volatile organic compounds analysis, gas chromatography (GC) is one of the best choices to carry out this task, due to its high sensitivity and selectivity. As a result, an in-house on line GC System was developed for this purpose. It includes the following parts: 1. A stream selection device to connect and monitor the source water and treated water using one instrument. 2. A self-cleaning filter to remove sands and suspended solids from the source water before it is introduced into the sample concentrator. 3. A Purge and Trap (P&T) device (from Tekmar) to extract and concentrate the volatile compounds before the compounds being injected onto the GC column. Since GC is a gaseous device and analytes introduced into the GC must be in a volatile format, either in volatile organic solvent or in gaseous state. 4. A GC (from Hewlett-Packard) equipped with a Flame Ionization Detector (FID). 5. A computer with Windows xp and ChemStation to control the sampling valves through a DAQ (from National Instruments) and to control the GC and P&T through a GPIB-USB interface (from Agilent). To control cost, in the development of this system, the GC and P&T are retired from regular use but still in good working condition
