1,3,6,8-PYRENETETRASULFONIC ACID TETRASODIUM SALT 
M.F.: C16H6O12S4·4Na
CAS NO. 59572-10-0

SPECIFICATION

ADVANTAGES: 

• High Quantum Efficiency, Ideal for Monitoring as low as 50ppb for Cooling & 5ppb for RO
• Colorless at the Target Concentrations & Easy to Dissolve
• Inert Fluorescent Tracer. Great Compatibility with Water Treatment Chemical Formulations
• Dust-Free for Easy Handling
• Long-Term Stability, 3-Year Shelf Life in the Original Package
• Nontoxic and easy to handle. It can be blended virtually into any cooling product formulation.
• Its neutral PH value will not influence the cooling water PH
• Reasonable price than molybdate .

USUAL PACKAGE: 25kg net paper drum

STORAGE
98% solid PTSA is hydroscopic. After the original PTSA factory package is opened, the package must be carefully sealed again to avoid PTSA absorbing moisture and causing weighing error for later use.
10% solution is stored in a dark container with light shielding and ventilation.

SHELF LIFE: Three Years

APPLICATION
PTSA can be used in cooling tower, no matter their size or design,
as fluorescent tracing dye indicating water treatment chemical concentration.
Fluorescent-traced cooling water treatment product can be formed by blending 10% PTSA solution into existing products directly.
A fiber drum (25KG) containing 1,3,6,8-Pyrenetetrasulfonic Acid, Tertrasodium Salt (PTSA), CAS# 59572-10-0. It is recommended to blend FDX-98 dye with water treatment formulation in 1:1,000 weight ratio. The concentration should be controlled at 50-200ppb in recirculation systems for the best monitoring performance.

Typical Applications
Concentration monitoring and dosing control in cooling tower and RO applications.
