We are working with a food ingredient that is known to have lead, and are looking to establish an in-house monitoring program to examine the content of lead in this ingredient.
Ideal limit of detection is < 10 ppb and no more than 15 ppb.
We were sending the samples to an external lab, but the test is expensive and results take several days to be received.
We are looking for a method that we can implement in house that is reliable and can give us a good idea on the lead content of the ingredient. We would still send some samples to the external lab for verification but we are hoping that we can also manage some of the testing internally to save on costs and time.
Does anyone have any recommendation for this program or is familiar with a lead testing equipment / test kit that can be used internally?
