Description
The Nextteq n-Butylamine Tube No. NX108VL provides direct measurement of n-butylamine from 1–20 ppm using a single 100 mL pump stroke and a clear pale-purple-to-pale-yellow color change, with the tube scale calibrated on ammonia and n-butylamine concentrations determined via a simple conversion chart. With a 3-year shelf life, a narrow 59–77°F operating range, and calibration by permeation tube method, this tube is well suited for workplace and process monitoring relative to the 5 ppm TLV-C guideline, noting that other amines can produce similar stains and lead to higher readings.
