Frequently Asked Questions

A matrix or baseline sample allows you to screen a blank matrix for analytes of interest, endogenous compounds, and interference with your test method.

When you purchase custom products with 3P BioSolutions, we prefer to send you a sample of the matrix so you can approve the lot before we manufacture your order. This helps avoid costly delays.

We include Certificates of Analysis with every order.  Need another one?  Email [email protected] with the product and lot number you’d like a CoA for and we’d be happy to send one over.

Our preferred carrier is FedEx, and we typically prepay and add to invoice.  If you’d like us to use an alternate carrier or your shipping bill to account, just let us know!
