Dry Calibration Standards

Avoid challenges associated with liquid standards and
pipetting

Dry standards are foolproof vials filled with impregnated activated carbon spiked with a NIST-traceable mass of mercury. They are dispensed by simply opening the vial and pouring its contents into a ladle. Standards can be created at custom mass levels based on your calibration needs, and each lot includes Ohio Lumex Chain of Custody Documentation.

Our line of Dry Calibration Standards is specifically designed for calibration of the M324 Sorbent Trap Analysis System.
