Appendix J: Using the Secondary Solid Standard
Introduction
The Solid Standard (P/N: 2300-900)
for the C3 Submersible Fluorometer
provides a very stable fluorescent
signal which can be adjusted to:
• Match a specific sample
• Create a calibration correlation
Once a correlation is established
between the Solid Standard and a
liquid primary standard or typical
sample it can be used for future
calibrations. The Solid Standard can
also be used as a stable reference
point for checking signal stability
and/or instrument drift.
Benefits
• Adjustable for a range of
concentrations
• Can be used for quick and easy
correlation.
• Can be used for multiple sensors
• Set screws ensure accurate
positioning
Features
Installation and Use
1) To establish a correlation between
a known concentration and its
respective fluorescence output,
immerse the sensor in a sample
with a known concentration of
your fluorophore.
2) Dry off the C3 Submersible
Fluorometer’s optics, attach the
Solid Standard Cap.
3) Align Solid Standard Cap numbers
with C3 sensor head numbers and
snap on the Solid Standard Cap.
4) Slightly rotate cap until it is set into
position. Note: You will feel/hear
a click when cap is positioned.
5) Insert up to 3 Solid Standards into
the desired optical port position of
the Solid Standard Cap.
