User-optimized emission test chamber systems with integrated online measurement system and automatic valve switching
EPH has developed low-maintenance emission test chambers that have proven themselves in daily use. The integration of an innovative analysis system for formaldehyde determination with valve switching from Grecon significantly reduces analysis effort and response times for process intervention.

method, the chamber gas is extracted from the test chamber using sampling pumps and passed through washing bottles in which formaldehyde is bound in an aqueous absorption solution. The subsequent quantitative determination is carried out using the acetylacetone method (Hantzsch reaction), in which formaldehyde is detected photometrically as a yellow-colored complex. This classic method is chemical-intensive and requires extensive laboratory equipment for several consecutive, time-consuming steps, including calibration. The implementation of a laser-based online measurement system fundamentally modernizes this process. All chemical reagents and large parts of the technical laboratory infrastructure are completely eliminated. The system enables direct, continuous measurement of the formaldehyde concentration in the chamber gas. Using automated valve switching, a single analyzer can sequentially monitor up to ten test chambers, thus ensuring clear, chamber-specific measurement. In addition, during the test, the integrated control system detects when the termination criterion defined in DIN EN 717-1 has been reached and reliably signals the end of the test to the operator. This provides the user with an innovative complete system that enables time-optimized, resource-efficient, and standard-compliant determination of formaldehyde emissions. The chamber system also meets the strict requirements for test parameters for determining VOC emissions for healthy indoor products. The systems will be offered by EPH GmbH and Fagus-GreCon Greten GmbH & Co. KG.
In established testing practice in accordance with DIN EN 717-1, formaldehyde emissions from products are measured using the test chamber method.
