Gas Analyzer
The Thermal and Evolved Gas Analyzer (TEGA) is a scientific instrument aboard the Phoenix spacecraft. TEGA's design is based on experience gained from the failed Mars Polar Lander. Soil samples taken from the Martian surface by the robot arm are eventually delivered to the TEGA, where they are heated in an oven to about 1,000ºC. This heat causes the volatile compounds to be given off as gases which are sent to a mass spectrometer for analysis. This spectrometer is adjusted to measure particularly the isotope ratios for hydrogen, oxygen, carbon, nitrogen, and heavier gases. Detection values as low as 10 parts per billion. The Phoenix TEGA has 8 ovens, which are enough for 8 samples.
Trace Ammonia Analyzer
* Unparalleled Precision
* Ultra-high Sensitivity
* Extremely Fast Response
LGR’s Trace Ammonia Analyzer (TAA) provides fast measurements of ammonia in ambient air with unparalleled precision and sensitivity. No longer do you have to wait for minutes before getting a useful reading – LGR’s TAA provides measurements every second with sub-ppbv precision. In addition, the TAA can report measurements quickly over a wide range of ammonia concentrations. For your convenience, we offer two versions of the TAA. If you require the fastest response rate possible (data rate up to 20 Hz), you will want to use our Trace Ammonia Analyzer - Fast. For applications requiring measurements of NH3 with highest accuracy, you’ll want the Trace Ammonia Analyzer – High Accuracy. In general, LGR Analyzers are not adversely affected by other atmospheric gases (no cross interferences) or changes in atmospheric pressure. Due to our low-power requirements, LGR analyzers may be operated on battery power with an appropriate AC/DC voltage inverter.
The Trace Ammonia Analyzer - Fast is designed to suit many applications including eddy correlation flux measurements using established micrometeorological techniques, which require response rates above 10 Hz.
The Trace Ammonia Analyzer – High Accuracy is designed for applications that require the highest sensitivity, precision and accuracy like semiconductor process monitoring and ambient air monitoring.
For customers interested in a less expensive ammonia analyzer with very high precision and fast response time, LGR offers the Economical Ammonia Analyzer.

Economical Ammonia Analyzer
* High Precision
* High Sensitivity
* Simple to Use
* Extremely Wide Dynamic Range
* Economical of Own and Operate
LGR’s Economical Ammonia Analyzer (EAA) provides sensitive measurements of ammonia in ambient air or in industrial process flows with extremely high precision and sensitivity. No longer do you have to spend a lot of money or wait a long time to measure ammonia with high sensitivity – LGR’s EAA provides measurements every second with ppbv-level precision. In addition, the EAA can report measurements quickly over a very wide range of ammonia concentrations. The instrument, based on LGR’s cavity enhanced laser absorption spectroscopy, is simple to use, inexpensive to operate, and includes all components (internal vacuum pump, keyboard,mouse, video monitor) to start recording data within minutes. Other atmospheric gases, including water vapor, carbon dioxide and methane, do not interfere with the ammonia measurements. The instrument includes an internal computer that can store data practically indefinitely on its internal hard drive (for unattended long-term operation), and that can send real-time data to a data logger through its analog and digital (RS232 serial) outputs. In addition, an Ethernet connection allows remote access to data files stored on the instrument’s hard drive. LGR’s EAA provides the high quality data necessary for the most demanding applications including semiconductor process monitoring and atmospheric trace gas monitoring. For customers interested in the highest precision with extremely fast response time, LGR offers the Trace Ammonia Analyzer.
