Miniature pumps with extremely long service lives by Schwarzer Precision (Germany) are some of the main components in portable gas analysis devices. Indispensible for reliable functioning, these devices cannot be small enough not to hamper their carriers – and to even save lives, when it counts.
The pump steadily sucks in the ambient air and transports it to the sensor for analysis. Apart from absolute leaktightness to prevent falsified analyses, minimum power consumption if also very important. This is the only way for the accumulators, and thus the devices, to become increasingly smaller.
Industrial Air Pollution Monitoring A. G. Clarke (Editor)
Hardback • 324 pages Pub date: 1997 ISBN: 9780412633904
Online price: £137.71 (RRP: £153.00)
The worldwide smallest eccentric membrane pump from Schwarzer Precision meets all these requirements. With dimensions of merely 13 x 22 x 32 mm and a weight of only 15 g, the SP 100 EC guarantees perfect measuring results. Optimally coordinated pump components and the innovative High Response Valve System permit this maximum reduction. And thanks to the modular design, the miniature pumps from Schwarzer Precision are adapted exactly to customer preferences. The objective at Schwarzer Precision is: Smaller and smaller, better and better! Revolutionary developments are part of the Schwarzer standard program.

airborne particles into a liquid media.
The liquid sample delivered gives access to cultivable, viable and non cultivable flora thanks to its compatibility with a large range of analysis including microbiology, immuno-assays, PCR, flow cytometry...
Giving accurate and reliable results in only few hours, it has been validated for indoor and outdoor air monitoring and it can efficiently collect
airborne pollens, bacteria, spores, molds and even airborne viruses... According to ISO 14698 recommendations, Coriolis®
µ is a perfect solution for the collection of bio-particles as far as it has
a d50 (the particle diameter at which the sampler efficiency is less than 50%) easily below 0,5µm (HPA report no 41/08). A high air flow rate (up to 300L/min) can be set to collect a representative sample and improve the probability of detecting a large panel of micro-organisms even if a low concentration is in the air. The collection efficiency has been tested by Pfizer US, and results have been published their results during the 4th Annual Global Conference on Pharmaceutical Microbiology (PDA) of October 2009.

A New Clever Solution for Measuring NOx The new Limas23 from ABB (UK)s a compact solution for the continuous measurement of nitrogen oxides, sulfur dioxide and
oxygen in one analyser. This specialist measures the components NOx as NO and NO2 without the use of a converter. The Limas23 is fully certified according to EN14181 and has an integrated web server with Ethernet connection.
Nitrogen oxides (NOx) are considered to be environmentally relevant gases, which cause harm to human beings and environment. NOx emissions are therefore limited. In Europe the NOx limits and their monitoring are specified for the individual emission sources in Directives. Energy generators, such as power stations, refuse incineration plants and boilers, are typical
emission sources, but automobiles, aircraft and ships and some chemical processes also emit NOx.

Titan industrial FTIR systems from MIDAC (USA) provide real-time, multi-component extractive gas phase analysis for applications including industrial hygiene, CEM, process optimisation/control, specialty gas QC, and research. The rugged industrial spectrometer is packaged with externally mounted, corrosion-resistant gas cells. Cell pathlengths range from 1cm to 60meters. Thermal isolation from the spectrometer allows operation from ambient to 240ºC, allowing moist sample streams to be analysed without condensation.
Titan gas analysers feature new dual ADC architecture and advanced mirror drive
control electronics. Combined with customised IR detectors for ultimate sensitivity, these systems can achieve low ppb detection levels for most of the compounds of interest, including formaldehyde, in real world conditions.
MIDAC’s powerful, fully proven AutoQuant Pro™ software package is optimised for quantitative gas phase analysis and can provide simultaneous display of trend charts, IR spectra, and concentration tables. MIDAC’s Standards digital spectral library, which contains over 150 of the EPA’s HAPs (Hazardous Air Pollutants), completes the Titan package for turnkey analytical capability.
Online, multi-stream models are available with NEMA rated enclosures and fully automated valve control for unattended operation. In addition, systems can be equipped with optical switching between sample cells to accommodate the need for different sample pathlengths or to prevent cross-contamination.
