ICP-MS Aluminum Levels Verification

Need a Canadian expert to confirm false positives of ICP-MS – we need to investigate the discrepancy in detecting the presence of aluminum in our products. We need either advice or an expert to write a letter to show the buyers that this can happen. Is there a list of highly qualified lab recommendations for ICP-MS that can do the corrections needed to obtain accurate readings and prevent false positives?

We’re a small business and this may have us looking at potential lawsuits from our customers.
