The GT90 Dioxin+ is designed specifically for an automatic and long-term sampling of dioxin emissions. The MCERTS certified system represents the cutting-edge technology for dioxin sampling and fulfills all requirements of the dioxin measurement standard. The system can be used in a variety of industrial processes such as waste incineration and cement production. Gasmet offers a full dioxin sampling solution package which consists of a system, lifetime service and support, documentation and training, and our expertise of over 30 years.

Solution for Long-term Sampling

The system is the perfect solution for the long-term isokinetic sampling of hazardous organic compounds in industrial and domestic waste incineration plants. In addition to dioxins, the system is capable of sampling furans and other persistent organic pollutants (POPs), such as polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs). To get even more out of the system, the GT90 Dioxin+ can also be equipped with the ParTrace option, enabling heavy metal and fine dust collection.

Technical Highlights

  • Automatic isokinetic sampling according to EN1948-1 / TS 1948-5
  • Dilution method enabling easy sample handling
  • Designed for industrial applications, especially for waste incineration
  • MCERTS certified solution
  • Lowest dioxin and dioxin-like compound concentrations can be sampled
  • Sampling up to 6 weeks
  • Allows remote access & control of the system

Dioxin Detection Technology Designed and Built for Purpose

Today, the Industrial Emissions Directive (IED) and some industry-specific BREF/BAT documents require monitoring of dioxins. The GT90 Dioxin+ was specifically designed to fulfill these limits and sample even the lowest dioxin and dioxin-like compound concentrations in harsh industrial environments.

Unparalleled performance

Dioxin detection isn’t an easy task. This system has however been performance tested and validated, allowing measurements down to 0.0003 – 0.252 ng I-TEQ /m³. The system can withstand dust loads up to 150 mg/m3 and velocities up to 30 m/s without any effect on the performance. In short, this is a top-of-the-line solution.

Method for reliable dioxin sampling

The system uses the dilution method according to the EN 1948-1 standard. Thanks to the heated sample line and dilution method used, the system works free from condensation. After the sampling period ends, the dry filter unit is transported to an accredited laboratory for analysis. The dry sample is easier to transport to the laboratory and the dry sampling method is also more reliable since no condensate is formed which would need to be transported for analysis as well.

 Features that take the sampling to a new level

This minimizes the need for probe unit maintenance and makes sure that no dirt will enter the system. The system can also be equipped with remote access and control, allowing e.g., remote calibrations, leak tests and data download during operation.

Low temperature for sampled dust

In flue gas, dioxins are mainly absorbed on particles but also evaporated in the gas phase. When sampling, the flue gas is cooled down with dilution air to ensure that a high portion of the gaseous dioxins is or remains absorbed on the particles. At this low temperature, no further chemical reactions (losses) or synthesis (production) are possible, making the results accurate and reliable.

GT90 Dioxin+ versions

There are two versions available, Standard and Compact. The Standard version has two probes, which is especially good for stacks with large diameters. It also has the ParTrace option, which enables fine dust and heavy metal sampling. The Compact version has one probe and is more suitable for stacks with smaller diameters. Both are MCERTS certified providing high-quality measurements.

GT90 Dioxin+ System Overview

The system consists of a heated sampling probe unit, heated line and control cabinet.  The system has titanium probe tubes and cartridges as a standard. For very harsh measuring point conditions we can optionally provide titanium heat exchanger and sampling probe unit valves:  In this case, all materials in contact with the sample gas from the tip of the probe tube to the cartridge would be titanium.

Dioxin Sampling Requirements in Waste Incineration Plants

In December 2019 the BAT (Best Available Technology) Conclusions document for Waste Incineration plants (WI BAT) was published under the Industrial Emissions Directive (IED). There the new BAT-Associated Emission Levels (BAT-AELs) for the dioxins and dioxin-like PCBs were set. The BAT-AELs work as a framework for authorities to set plant-specific ELVs, i.e. Emissions Limit Values. You can read the more in-depth report here: WI BAT conclusions published – key findings in emissions monitoring.
