Brimrose NIR Analyzer
A new series of miniature near-infrared (NIR) spectrometers is said to offer a cost-effective tool for inspecting incoming raw materials and product quality control. Compact, battery-powered Model 5030 ATOF-NIR Portable Analyzer from Brimrose Corp. of America, Baltimore, allows laboratory tests to be performed anywhere in a plant environment. The instrument, which sells for $28,000 (compared with $40,000 for larger units), is reportedly insensitive to ambient light, vibration, dust, and dirt. Its design allows for quick switchover from solids to liquids, and results appear instantly on its LCD. Applications include material identification or measurement of moisture content and active-ingredient levels. Once the instrument is calibrated, it reportedly can be used by an inexperienced operator.

CO2 Isotope Analyzer
* Measures 13C/12C in carbon dioxide
* Extremely wide measurement range
* Low power requirement (120 W with internal pump)
* Easy to use
The CO2 Isotope Analyzer is an autonomous instrument capable of measuring the 13C/12C ratio in ambient carbon dioxide with better than 0.25‰ repeatability (for an integration time of 60 seconds) and without the need for costly consumables. This is possible because the instrument itself is built around conventional telecommunications-grade diode lasers that operate in the near-infrared spectral region. In addition, since the measurement strategy is based on high-resolution direct-absorption spectroscopy (see www.LGRinc.com, Theory Section), the instrument is not affected by other atmospheric gases or by changes in ambient atmospheric pressure. Thus the need for regular calibration with expensive reference gases is also significantly reduced compared with traditional analytical instruments.
The instrument includes an internal computer that can store data practically indefinitely on its hard drive (for applications requiring unattended long-term standalone operation), and send real-time data to a data logger through its analog, digital (RS232), and Ethernet outputs.

INFRARED ANALYZER
INFRARED ANALYZER
The above diagram provides a graphic representation of the basic design of an infrared analyzer which is used to measure breath alcohol concentrations. The design is based on the fact that specific wavelengths of infrared energy are absorbed by ethyl alcohol molecules. In its simplest form, the instrument's detector measures the change in the amount of a specific wavelength of infrared energy that passes from the infrared source (lamp), through the sample chamber and filter wheel to the detector. The change in response on the detector, as a breath sample is submitted to the sample chamber , is monitored and analyzed by a processor in the instrument. The change in the signal is used to calculate an alcohol concentration

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.
