NAGCO Benzene Specific Detector Tubes 0.5-10 ppm | N10-101-01

The NAGCO N10-101-01 Benzene Specific Detector Tubes provide direct-reading measurement of benzene (C6H6) in air using a manual gas sampling pump. The standard measurement range is 0.5–10 ppm using three 100 mL pump strokes for a total sample volume of 300 mL.

For applications requiring measurements outside the standard range, the N10-101-01 can also be used from 0.25–5 ppm using six pump strokes or from 1.5–30 ppm using one pump stroke with the appropriate correction factor.

Cross-Sensitivity & Interferences

The N10-101-01 uses a pre-tube to help remove interfering compounds. NAGCO documents cross-sensitivity testing with isobutylene, n-hexane, n-heptane, toluene, m-xylene, methane, carbon monoxide and hydrogen sulfide. Hydrocarbons and similar reducing gases are listed as other possible interferences. Refer to the NAGCO datasheet for complete cross-sensitivity and correction information.

Pump Information

NAGCO recommends using NAGCO detector tubes with NAGCO sampling pumps. CPS Calibrations can assist customers transitioning from another detector tube system with selecting the appropriate NAGCO tube and sampling equipment for their application.

Important: Detector tube readings may be affected by temperature and interfering compounds. Always follow the NAGCO datasheet and pump operating instructions for the specific measurement being performed.
