Learn about the importance of sample lines in achieving perfect results from your CEMS
A recent article, written by Tobias Henrich, the expert in heated sample lines who works for AGT-PSG in Germany, emphasises the importance of
the sampling apparatus and set up if you are to achieve maximum accuracy from your CEMS. This article is available to download for free on
www.envirotech-online.com.
Whilst much time and investment is spent on the analyser itself, the importance of achieving a perfect sample, in some very difficult environments in which to operate is a vital consideration that can be overlooked. CEMS operators now have the opportunity to significantly improve their analytical technology’s performance and reduce long- term costs significantly. Mr Henrich discusses how the accuracy and longevity of the system can be improved by focusing on how to achieve reliable and trouble-free samples and reduce costs and time lost from needing top perform tiresome maintenance tasks.

New series of portable isokinetic samplers for stack emissions
Mega Systems have recently launched the Lotus, a new handheld isokinetic controller in compliance with EN 15259, UNI EN ISO, 16911-1, EN13284-A, ISO 9096.
The instrument has a 4.2” colour LCD display, a USB port for easy report downloads through a pen drive, and a rechargeable lithium battery to ensure wide range working autonomy. Three independent sensors for barometric, static and differential pressure, guarantee reliable and highly accurate measurements of flue gas conditions, calculating velocity and flow rates in real time.
Lotus can be used with a Darcy tube for stack inspections and measuring thermodynamic parameters or with the Aster isokinetic pump and a sampling probe (heated or non-heated) for complete automatic samplings.
The instruments connect via serial RS 232. Lotus reads flue gas velocity and flow rate through the Darcy tube and the differential pressure sensor and then regulates the pump suction power accordingly to quickly track variations while remaining within the correct isokinetic grade.
The Aster isokinetic pump is equipped with a 7” touch screen display, allowing easy and convenient set up and data review.
Through the display, it is possible to check the sampling data, view its progress (textual or graphic), manage the integrated database and carry out diagnostics. As per tradition, control, flow rate regulation and compensation are completely automatic. The pump guarantees high precision in regulating flows throughout the operating range.
The high prevalence of the pump (> 600 mmHg), combined with the electronic management and control system, enable automatic compensation for variation in load losses caused by filter clogging, and maintenance of constant flow rate throughout the sampling period. Whenever an alarm situation arises (failure to maintain constant flow, power failure, etc.) the anomaly is recorded and reported.
The volumetric meter is a dry type with ± 2% accuracy. An electronic sensor detects the temperature of the air sampled at the meter inlet to calculate volume normalisation. The reduced weight and dimensions of all models allow for easy portability even in areas that are difficult to access. Aster has a dual power supply: it can be powered by a fixed network or via the optional battery box.

Ambient air Quality monitoring System is a systematic, long-term facility to measure wind speed, direction, other weather parameters, concentration of air pollutants (such as SO2
, THC etc), and particulate matters (PM2.5, PM10) in the
surrounding, outdoor air continuously all year round. The monitoring station is tailor-made according to the customer’s special request.
