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:

Turnaround Time

We make every effort to complete analyses within 5 working days.  Upon completion, your results will be reported by e-mail, fax, phone or mail. Priority and Same Day service is available for those times when a faster turnaround time is required.  Please call ahead for scheduling Same Day service.

Re-checks

Rechecks will be performed at your request.  Should the recheck confirm the original analysis, you may be charged for both.  Should the recheck differ significantly from the original analysis, you will not be charged for the recheck.
