New GSM/GPRS/EDGE Wireless Analyser

2009-02-24T05:34:00.000-08:00

Europe : NetHawk is introducing a new release of their analyser, the main new functionalities being intended to help the user in testing of a live GPRS/EDGE network by any major vendor.
One of the main new features is the correlated multi-interface call trace, which makes it easy for the user to follow all the ongoing circuit-switched calls and packet switched sessions in real time in Gb, Abis, and A interfaces. This, combined with the extended physical link capacity through the NetHawk portable C8 multiplexer, and powerful new filtering features make for the most advanced and versatile protocol testing tool on the market. NetHawk is not sacrificing ease of use for the added functionality; the new analyser’s Dynamic Abis support, along with other optimisations to the user interface, minimises the need for configuration and enables more efficient testing work.
The capabilities of the NetHawk Analyser have been further enhanced by including support for the SS7 and SigTran protocols, as well as for 2-Mbps HSL (high-speed signalling link) interfaces. In addition to this, the NetHawk Analyser can also handle Gb deciphering in real time in both Gb over Frame Relay and Gb over IP implementations. To respond to modern Europe’s railway operators’ needs, NetHawk is also introducing support for decoding GSM-R (GSM – Railway), which is the standard chosen by several railway operators for operational communications.
All these new features, combined with the unmatched portability of NetHawk tools, provide strong support to NetHawk’s customers in their efforts to develop their networks for new services and revenue sources, as well as for troubleshooting their live networks for increased quality and performance.

CleverStat is a nifty tool I've been using recently for web site content analysis. Unlike numerous online apps, CleverStat makes a copy of the site on your hard drive and analyzes the entire thing and not only individual pages.

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

CO2 Isotope Analyzer

2009-02-23T02:57:00.001-08:00

* 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.

Economical Ammonia Analyzer

2009-02-23T02:56:00.000-08:00

* 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.

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.

Gas Analyzer

2009-02-23T02:52:00.000-08:00

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.

A residual gas analyzer (RGA) is a small and usually rugged mass spectrometer, typically designed for process control and contamination monitoring in the semiconductor industry. Utilizing quadrupole technology, there exists two implementations, utilizing either an open ion source (OIS) or a closed ion source (CIS). RGAs may be found in high vacuum applications such as research chambers, surface science setups, accelerators, scanning microscopes, etc. RGAs are used in most cases to monitor the quality of the vacuum and easily detect minute traces of impurities in the low-pressure gas environment. These impurities can be measured down to 10 − 14 Torr levels, possessing sub-ppm detectability in the absence of background interferences.

RGAs would also be used as sensitive in-situ, helium leak detectors. With vacuum systems pumped down to lower than 10 - 5Torr—checking of the integrity of the vacuum seals and the quality of the vacuum—air leaks, virtual leaks and other contaminants at low levels may be detected before a process is initiated.
