Request for Proposals for the Purchase of Two Gas Chromatography Coupled with Single Quadrupole Mass Spectrometer (GC-SQ) Systems for the Orange County Water District

The Orange County Water District (District) is soliciting proposals from qualified vendors to provide two GC-SQ Systems for the Laboratory.


The District was formed in 1933 by a special act of the California State Legislature to protect Orange County’s rights to water in the Santa Ana River and to manage this important groundwater basin.

Since 1933, the District has replenished and maintained the groundwater basin at safe levels while more than doubling the basin’s annual yield.  This important source provides local groundwater producers with a reliable supply of high-quality water.

One system must be fully compliant with EPA Method 524.2 for the determination of volatile organic compounds, using a purge-trap system.
