ISO 17226-1 Chemical Determination of Formaldehyde Content in Leather - Part 1: Standard Test for Method Using High Performance Liquid Chromatography

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 17226-1 testing. This standard specifies a method for the determination of free and released formaldehyde in leathers. Based on high performance liquid chromatography (HPLC), this method is selective and insensitive to colored extracts and is intended for the precise quantification of formaldehyde.

The formaldehyde content is taken as the amount of free formaldehyde and formaldehyde extracted from the skin by hydrolysis in a water extract under standard conditions of use.

The process is selective. Formaldehyde is separated from other aldehydes and ketones as a derivative by liquid chromatography and its amount is determined. The detected free formaldehyde and formaldehyde are hydrolyzed during extraction to yield free formaldehyde.

The sample is decomposed with a detergent solution at 40°C. The eluate is mixed with 2,4-dinitrophenylhydrazine, where aldehydes and ketones react to give the corresponding hydrazones. They are separated by a reverse phase HPLC method, which is detected and quantified at 360 nm.
