Standards

Analytical standards and internal standards play an important role in providing accurate test results. One of the major items developed at PSI is the manufacture of  Standards and Internal standards used for HPLC, HPLC-UV, UPLC-MS/MS, and GC/MS analysis. Other standards and internal standards were prepared at the request of members of the dietary supplement industry and are available to laboratories both in bulk (mg to g quantities).

Note:  For other standards or internal standards, please inquire.
