BPA/BPS Testing of Thermal Receipt Paper

We’re looking to test thermal receipt paper for BPA and BPS residues. Our available sample is < 1 gram (one receipt).

Would you please confirm if your lab can:

• Accept sub-gram receipt samples (single receipt) for LC-MS/MS analysis;
• Provide quantified results (not just presence/absence) with stated LOD/LOQ;
• Share turnaround time and pricing for this smaller-mass test?

If helpful, we’re fine with micro-punching/shaving the receipt. Please also let us know your preferred packaging, minimum sample size, and any chain-of-custody requirements.
