Sample Collection

Sampling is a crucial part of the analytical process.  When trying to establish the homogeneity of a lot, several samples should be taken from the lot of material and analyzed individually.  When checking for inclusion of ingredients in blended material, several samples should be taken and composited for analysis.  The sample should be large enough to ensure that it is representative.  For most analyses a 100 g (4 oz.) sample is adequate.

Sample Submission

Samples submitted should be accompanied by the following information: company name, contact, complete address, phone number, fax number, customer PO #, sample identification, analyses desired and expected levels or range.  The expected levels are useful for determining the dilution and for matching the matrix in order to minimize interferences.  Samples that do not have expected levels may require a second assay that will delay results.  The sample should be sent to:
