HT8700 Open-path NH3 Analyzer

Product Introduction

The HT8700 Open Path Ammonia Analyzer is an instrument designed to measure the concentration of ammonia in the atmosphere with high accuracy. The following is a detailed introduction to the HT8700:

How it works

1. Quantum Cascade Laser Absorption Spectroscopy (QCLAS):

   • Laser source: The HT8700 uses a mid-infrared quantum cascade laser (QCL), which can emit light in the characteristic absorption band of ammonia. QCL has high sensitivity and high resolution, and can accurately measure the weak absorption signal of ammonia.

   • Optical path design: The instrument uses two high-reflectivity mirrors to design an open path, so that the laser is reflected multiple times in the atmosphere, forming an effective optical path of tens of meters. This can enhance the interaction between light and ammonia and improve detection sensitivity.

2. Absorption peak measurement:

   • Spectroscopic analysis: The instrument determines the concentration of ammonia by measuring the absorption of laser energy by ammonia at a specific mid-infrared wavelength. The spectrum curve of the absorption peak is integrated in real time to invert the trace concentration of the gas.

Features and advantages

• High Accuracy and High Sensitivity: The HT8700 provides high-precision ammonia concentration measurement and is suitable for applications requiring high-sensitivity detection.

• Real-time data: Able to display and record changes in ammonia concentration in real time, supporting real-time environmental monitoring and data analysis.

• Durability: Designed to withstand a variety of environmental conditions, including varying climate conditions and terrain.

Application areas

• Environmental Monitoring: The HT8700 is widely used to monitor and study ammonia emissions in the atmosphere, such as in agriculture, industrial emissions, and landfills.

• Climate research: Helps quantify the impact of ammonia on climate change.

• Ecosystem research: The HT8700 can be combined with a flux observation system to measure the ammonia net exchange flux in different ecosystems.
