Paulson, still semi leaded??? (2 Viewers)

[Jacks]

Weird, maybe the lead test is fake, but it reliably says no lead to BCC and CPCs, but I can’t find a Paulson chip with no reaction.

The known leaded chips do react visibly more.

Lead test kits that can be purchased for public use are notorious for false positives, IIRC.

It’s reliably indicating Paulson, so if false positive I’m guessing it’s detecting something that’s strongly correlated with the presence of lead and Paulson just happens to use it in their formulation as well.

But I’m wondering if there are any chemists that can help out!

I'm an organic chemist. I don't have much experience with lead, but I was working with it in large quantities for a reaction I was doing a couple years back. I needed to have a safety control for my risk assessment, and I was recommended D-Lead as a test kit by the safety officer because apparently there were no other options on the market/everything else was poor. I'm also not too convinced with how the cotton swab works as a one-step process.

That being said, if anyone has more experience I'm happy to be corrected.

Looking forward to seeing who has more experience than an organic chemist who worked with it in large quantities

I think we have one or two people here who have experience with heavy metal characterization/XRD/Surface? They would know more than me. @LowerBama1714

Is cotton a heavy metal?

I remember that thread.. Let's not go there

Is cotton a heavy metal?

Depends on what weight cotton.

So uhh, are any of these possibly in Paulsons?
