GGA Standards

CPI International carries an advanced selection of Glucose-Glutamic Acid (GGA) Standards intended for performing BOD5 Testing applications and created in compliance with the Standard Methods for the Examination of Water and Wastewater. Our GGA standards undergo stringent quality control testing and examinations including Total Organic Carbon, COD, conductivity, and heterotrophic plate count. All GGA Standards are well-packaged and safely stored in sterile plastic vials with a screw-off-cap closure for convenience.

We also offer custom standard requests to reduce workload and increase laboratory performance efficiency. Our reference materials are available in 1mL ampules or two 0.6mL ampules to increase your shelf life at no additional cost.

A certificate of analysis and a material safety data sheet are shipped with every standard and the accuracy of single element standards is guaranteed to ±0.3% for 18 months from the date of shipment.
