Turner Designs has released UV Solid Secondary Standards for the C3 Submersible Fluorometers. Instrumentation configured for UV analyses typically rely on the use of liquid standards, such as Quinine Sulfate, for ensuring instrument integrity.
However, transporting and preparing liquid standards can be tedious and sometimes hazardous. The UV Solid Secondary Standard is compact, light weight, and safe to use as a convenient way to quickly check the stability of the Crude Oil, Refined Fuels, Dissolved Organics (DOM), and Brightener/Whitener sensors.
To ensure data integrity, the UV Solid Secondary Standard can be read before and after a deployment or sampling event. And, establishing a correlation between a primary standard’s known concentration and the UV Solid Secondary Standard’s signal eliminates the ongoing need for costly and time-consuming liquid calibration standards.
The UV standard (PN 2300-902) is inserted into the Solid Standard cap (sold previously including non-UV standards as 2300-900 and available separately now as 2300-905).
