A barium sulfate water-extract conductivity result is incomplete without the extraction procedure. Compare results only after the water, powder ratio, temperature, time and measurement method are aligned.
Keep the extract separate from the whole powder
Conductivity describes an electrical property of the prepared liquid under its test conditions. It does not identify every dissolved species, establish total BaSO4 purity or prove corrosion performance in a finished coating. Ask for the specific chemical evidence when those are the purchasing questions.
Vanderbilt Minerals’ paint filler reference provides mineral-filler selection context. It is not a substitute for the offered grade’s agreed extraction method or an ENVO test limit.
| Method field | Why it matters |
|---|---|
| Water blank | Separates the test water and equipment contribution |
| Mass-to-liquid ratio and extraction | Defines the sample being measured |
| Temperature and instrument conditions | Makes the electrical result comparable |
| Acceptance basis | States what decision the result supports |
Investigate a high result without inventing the cause
Repeat or investigate under the quality team’s approved procedure, retaining the initial finding. If a specific ion or contamination source is suspected, use an appropriate analytical method rather than naming it from conductivity alone. A low extract result does not waive unrelated grade requirements.
Send ENVO the current method, units, extraction conditions and intended coating requirement. Request actual lot evidence where agreed. This question is separate from coarse-particle defects: an electrical extract test cannot establish the absence of coating specks.
