Nitrogen-phosphorus detectors (NPD) for gas chromatography are specific to nitrogen- or phosphorus-containing compounds and are well suited for environmental and forensic applications.

• Long-life bead
• More stable operation throughout the bead’s lifetime
• For nitrogen-containing compounds: similar sensitivity and selectivity specifications
• For phosphorous-containing compounds: superior sensitivity and selectivity specifications

Nitrogen-phosphorus detectors (NPD) for gas chromatography are specific to nitrogen- or phosphorus-containing compounds and are well suited for environmental and forensic applications. The key component to NPD performance is its bead. Agilent has acquired the worldwide manufacturing rights to the Blos bead, based on a high-performance glass material technology.
