5.4 Turbidity
The Turbidity channel has a detection range of 0.5 to 1000 NTU. A primary Turbidity
standard is required for calibration. We recommend using a Turbidity standard in the range
of 10 to 100 NTU. The Polystyrene cuvettes are preferred for best turbidity results.
Turbidity standards can be purchased from
GFS Chemicals .
10 NTU - GFS Part Number 8545
100 NTU - GFS Part Number 8546

5.5 Fluorescent Tracer Dyes
Fluorescent tracer dyes provide an accurate, cost effective method for measuring water flow
levels, mixing zones, time of travel, groundwater transport, leak detection, retention times,
etc. The two most commonly used tracer dyes are Fluorescein and Rhodamine WT. The
Fluorescein dye can be detected using the Blue channel on the
Aqua Fluor
®
and Rhodamine
dye is detected using the Green channel. The linear detection range for both dyes is 0.4 to
400 ppb (active ingredient) in potable water.

’ website under Applications.
5.6 Cyanobacteria Monitoring
The Cyanobacteria channel of the Aqua Fluor
®
detects the fluorescence of either
phycocyanin (PC) or phycoerythrin (PE) pigments unique to Cyanobacteria.
Note: Readings on the Phycocyanin channel using cuvettes or vials have a maximum
range of approximately 3,500 ppb. Minicells P/N 7000-950 and Minicell adaptor P/N
8000-936 are required to achieve maximum range of approximately 20,000 ppb.
The fluorescence is measured
in vivo , without extraction or chemical treatment. For many
types of qualitative work, in vivo measurements alone may provide sufficient information.
For quantitative measurements, in vivo data is correlated with other measurements, such as
cell counts or extracted pigment analysis.
