If anything smells off or separates weirdly that’s usually a raw quality issue not you

Most small labs can only do basic screens not full heavy metal profiling

A lot of solvent problems end up being contaminated or poorly dried powders.

Without ICP-MS or ICP OES their detection limits aren’t great

If the carrier looks cloudy after sitting it’s often impurities in the raw not the oil

A lot of heavy metal tests from small labs are just colorimetric kits not reliable

If your reaction is inconsistent from batch to batch it’s a supplier inconsistency

Turnaround time can be a clue real metal testing isn’t done in 24 hours
