Pyxis NDSA-10 Calibration Standard Solutions, 10ppb

Calibration solutions for handheld and inline devices able to monitor for NDSA (1,5-Naphthalenedisulfonic acid disodium salt, NDSA ≥95%).

The Pyxis NDSA-10 Calibration Standard Solution is a precisely formulated 10 ppb (parts per billion) reference solution designed for calibrating fluorescence-based sensors and instruments that detect 1,5-naphthalene disulfonic acid (NDSA). As a widely used fluorescent tracer in cooling water and closed-loop treatment systems, NDSA requires accurate low-level detection to ensure proper chemical dosage and system performance.
