Abstract Information :

The enormous pressure for operator of Continues Emission Monitoring Systems (CEMS) growth significant: On the one hand, measuring and detection limits and requirements for the availability increase, on the other hand less resources are assigned to this field.

Quality and Market's Maturity
From a global perspective, the quality and standards for Emission Monitoring vary depending on the maturity of the market. As some like the emerging markets come from a relatively low level they face the challenge to pick up to higher requirements in a relatively short time. Mature and established markets again are measuring since a longer time but often in lower detection or measurement limits - which brings other challenges to this group of markets. Another big difference next to the measurement limits is often in the requirements for the online time of the measurement. European standards require a downtime no longer than the maximum of 10 days per year. This legal requirement sounds generous and easy to be reached but due to the very tough rule that rounds single events to half or even full hours the offline limits are faster reached than expected - an additional reason for high quality standards for all qualified analyser systems.

The Symphony of Probe Sampling Components and Analyzer
For all extractive Continues Monitoring Systems the probe sampling and all its components make the difference. As the costs of In-Situ systems are within the operation phase often higher than expected extractive analyser system come with high number of advantages. As the measurement value is the result of the entire chain of probe sampling and analyzer performance all the components have to be harmonized like a symphony. This circumstance leads to a careful selection of the probe sampling components from a technical and commercial point of view.

The commercial view: Total Cost of Ownership
The above descripted limitation of resources many operator face consequences to focus on the right choice of the components for the Gas Sampling. Analytics show that the operation costs of an extractive probe sampling system represent approximately 2/3 of the Total Costs of Ownership. Sometimes very low initial investment costs lead into high operation and maintenance costs which will again affect the availability of the system. All components starting from the Gas Sampling probe with different filter surfaces and back purging options can be equipped with additional components in order to optimize the operation costs and online time.

The technical view: Technical basis also for future Developments
One of the main advantages of extractive CEM systems is to analyze multi components at the same time. Other than In-Situ technologies which often require one measurement unit for each component there are no limits for the number of components which are measured in an extractive sampling system. If the right probe sampling components were chosen it is even possible to reach lower detection and certification limits by only changing the analyzer at the end.
