Details

Features

  • Analyzer, flow cell, heat trace control, insulation, purge control, and wiring termination pre-integrated
  • Drop-in replacement for existing analyzer technologies
  • Integrated tube-in-shell flow cell allows for tight sample heating control
  • Pressure and temperature compensation included
  • Advanced diagnostics with 50 days of data and spectra storage

Reliability

Auto gain graphs

Reference Cell
Internal reference cell in the laser module ensures peak locking during trace measurement.

 

Auto gain
Auto-gain enables wide signal ranges against dynamic variation of transmission.

 

Validation
Validation can be initiated manually, remotely, or automatically on a daily, weekly or monthly basis defined by the user.

TruePeak

With TruePeak we can measure the area of the absorbance peak. This eliminates effects from changing background gases, allowing for simple pressure and temperature compensation.

Overview:

Blue ammonia represents a significant opportunity for the ammonia industry. Unlike “green” ammonia, which relies on renewable energy and is still in the early stages of development, blue ammonia can be produced using much of the same infrastructure already in place for grey ammonia.
