Air Monitoring 15 New Powerful
Portable FTIR Launched Protea (UK) announces the first of its new generation of FTIRs - the ProtIR 404 HL System for process and industrial measurements where it is essential to accurately measure very high (percent) level concentrations of complex gas mixtures.
At the core of this new product is a state-of-the-art high-resolution interferometer system and a fully heated measurement cell that is both extremely robust and easy to service. Combined with Protea’s advanced chemometrics, the result is a powerful instrument with extremely high performance standards.
The ProtIR 404HL is designed to be used in any application where engineers need to make high concentration measurements in gas streams, typically for process and emissions control. It can be customised to measure an extremely wide range of gases, including ‘difficult’ mixtures. The reliability of the system is enhanced by use of a “single pass” optical cell that has no optical mirrors and is therefore far less susceptible to contamination effects such as optical fouling, loss of signal and instrument drift.
The instrument can be used either as a portable unit or within a fixed system, depending on the user preference. The flexibility of FTIR with chemometrics means that any system can be configured to measure across a broad range of industrial
applications. Typical examples would be monitoring and control of pre-abatement streams of acid, inorganic and organic gases or control of complex speciated VOCs such as those found in Vinyl Chloride production.
The analytical power behind the ProtIR 404HL centres around Protea’s 16 year experience in deploying FTIR systems to make complex gas measurements in the chemical and pharmaceutical industries. With its own UK based application laboratory, Protea can quickly and efficiently create customer-specific chemometric models that are expertly configured and tested before site installation. For those customers who prefer to gain this expertise in-house, Protea can offer extensive training on application building and deployment. Either approach will ensure that each ProtIR 404HL always meets the customer’s exacting standards.

Standards Compared in Moisture Measurement at Leading Institutes
When four of the world’s leading national metrology labs took the bold step of comparing their primary moisture standards, the tool of choice --a Tiger Optics LaserTrace --performed admirably. Measurements deviated less than 2 percent over the course of the three-year, multinational inter-comparison, thereby permitting the facilities to establish a much-needed baseline for future work.
The groundbreaking study --undertaken by the European Association of National Metrology Institutes (EURAMET) --relied solely upon the company’s LaserTrace, along with a back-up compact HALO instrument, also fromTiger Optics (USA).
The performance of the Tiger Optics instruments permitted scientists to compare standard generation facilities by shipping the analytical instruments --in lieu of cumbersome standards --to the participants in the United Kingdom (National Physical Laboratory), the United States (National Institute of Standards and Technology), Japan (National Metrology Institute of Japan), and Germany (Physikalisch-Technische Bundesanstalt).
The measurement of trace amounts of moisture contamination is of utmost importance to a number of manufacturers and suppliers of purge and process gases. The semiconductor industry, for example, regards moisture as one of the most difficult impurities to measure and to control. As manufacturers develop moisture analysers to detect ever-smaller amounts of contaminants, there is an equally pressing need for traceable calibration. Hence, EURAMET’s desire to compare facilities and quantify the variability among the standards and their accuracy at fraction amounts.
Until this study, an inter-comparison of such facilities was untenable, due to the characteristics of trace water-vapour standards. Such standards are produced via a dynamic method, for example; gravimetrically, or a frost-point generation, involving large, weighty, and complex pieces of equipment that are not readily brought together for comparison purposes. To resolve that problem, EURAMET elected to transport instruments, rather than standards.
The study was designed to compare the performance of each of the national metrology institute’s facilities over the range of 10 ppb to 2000 ppb. For the first time, participating laboratories were able to quantify the comparability of their trace water- vapour standard generation facilities, which proved to be excellent across the full range of measured amount fractions, as the graph illustrates.
“While we learned that such studies take considerably longer than anticipated, the chance to support the noble aim of achieving a comparable moisture standard worldwide was well worth it,” said Lisa Bergson, Tiger Optics’ founder and chief executive, adding, “Beyond that, we are proud of our analysers’ precision and robust performance. It’s great to be in a position to offer them to our friends in the institute community.”

orders@ilmpublications.com New Marine Ultrasonic Anemometer
The Model 85106 Marine Ultrasonic Anemometer from RM Young (USA) is an accurate no-moving-parts wind sensor with features for the marine environment. A reinforced transducer array accurately measures wind speed and direction and provides a serial NMEA signal.
Analogue voltage signals are also available from the junction box. For extra safety and piece of mind, internal electronics are coated for moisture resistance. Bird spikes are also incorporated into the structure to discourage perching.
Reader Reply Card No. 48 Portable Heated Sampling Pipe
To fulfill latest standards for portable measurement one year ago JCT Analysentechnik (Austria) launched the portable heated gas sampling probe JPES.
In many applications like emission monitoring and measurements according to authority standards also grid measurements are an important topic. In this concern JCT are pleased to introduce their portable heated sampling pipe JBER. The heated sampling pipe JBER can be added seamlessly to their portable probe JPES.
No additional tools or other equipment is needed for mounting. No additional power supply is needed because the JBER is plugged in between heated hose and probe. Heating time of the complete heated sample extraction set is less than 15 minutes to be ready for measurement as fast as possible.
