Homogenizing your sample prior to analysis takes approximately 4 minutes.
The following steps will outline how to correctly homogenize a water/wastewater sample for PeCOD® analysis:
- Homogenize the raw sample for 2 minutes. Ensure you are using at least 50mL or more of sample.
- Prepare the sample with electrolyte in the range being used. Click here for the correct sample-to-electrolyte ratio for each colour range.
- For example, if you are using yellow range, take 2mL of sample plus 18mL of electrolyte.
- If dilution is required, prepare the dilution first with the homogenized sample, then prepare with electrolyte.
- Homogenize the mixture of sample and electrolyte for 1 minute.
- Place the PeCOD® intake tube (Port A) into the sample and press run the analysis.
- Rinse the homogenizer in deionized water, turn on for 30s while in DI water.
- Spray down homogenizer with DI water using a laboratory bottle with nozzle (common lab squeeze bottles).
