Our laboratory performs testing in accordance with DIN EN ISO 17226-1 professionally and in an accredited testing environment. This standard describes a chemical test method for determining the content of glutaraldehyde in leather. Glutaraldehyde is commonly used in leather production as a tanning agent or preservative and must be monitored due to potential health risks.
As part of the test procedure according to DIN EN ISO 17226-1, defined leather samples are comminuted and extracted with water under controlled conditions to transfer the glutaraldehyde into solution. The aqueous extract is then analyzed using high-performance liquid chromatography (HPLC). The standard specifies a selective and sensitive analytical method that enables reliable quantitative determination even in complex sample matrices.
In the test report issued by our testing laboratory, the glutaraldehyde content of the tested material is reported in mg/kg. The results support the assessment of chemical safety in leather and assist manufacturers and distributors in complying with legal requirements and industry-specific standards, particularly for leather products in the consumer goods, furniture, and automotive sectors.
