It is the policy of SOS Analytical, Inc. that all samples and results are the property of the client.

Samples are held for no longer than 30 days, depending on their stability and the amount of storage space required. Samples which require special means of disposal will be returned after analysis at the client's expense.

Quality assurance consists of a multitude of tests and includes initial calibrations, continuing calibrations, retention time checks, method blank analyses, method detection limit analyses and so on. The quality assurance program used by SOS Analytical, Inc. meets or exceeds that required by the analytical method. In addition to participating in the certification/accreditation programs for the state of Michigan, SOS Analytical, Inc. has its own internal quality control program where samples are analyzed to check the performance of all technicians and chemists. We also participate, on a bi-yearly basis, with a third party auditing program in which check samples are provided and the results are compared to the 'true' results and to the results reported by other laboratories in the country.


Our warranty is limited to the accuracy of analyses of samples as received. We assume no responsibility for the purposes for which the client uses the test result, nor liability for any other warranties, expressed or implied, including warranties of fitness for particular purpose or for merchantability made by the client. These terms and conditions shall supersede any conflicting terms and conditions stated on any purchase order, or other work order submitted by the client.
