Benefits of using the Solid Secondary Standard:
It can be used in place of a primary liquid standard once a correlation between a primary standard and the solid standard has been established (Blue PhytoFlash only).
It can be used to check the fluorometer stability, and/or check for loss in sensitivity resulting from the growth of bio-fouling organisms on the sensor optics.
One Solid Standard has two sides that yield either a High or Low fluorescence response. The Solid Secondary Standard provides a very stable fluorescent signal.
