Portable Screening Devices - DSC_0949

In this simulated demonstration, FDA scientists show how to evaluate dietary supplements for toxic metals using a portable XRF analyzer. Within 30 seconds, the instrument will indicate if the sample passes or fails the screening test. Samples are marked, packaged and sent to a lab for further testing.

Portable rapid spectroscopic technologies—which analyze the dispersion of an object’s light to determine the object’s chemical or molecular composition—may hold the key to a new era of product-safety screening. By allowing investigators to screen products earlier in the supply chain, these portable devices could significantly cut risks from contamination or counterfeiting of medicines, dietary supplements, cosmetics, and perhaps even foods.
