Development and validation of a UPLC-MS/MS method for the quantification of isothiazolinones in the composition and emissions from consumer products.

Isothiazolinones, a family of biocides, are used as preservatives for their fungicidal, bactericidal, and algacidal properties. These compounds can be found in a wide range of consumer and building products, such as paints, varnishes, shampoos, and liquid detergents. A robust analytical UPLC-MS/MS method to identify and quantify seven isothiazolinones (MIT, CMI, BIT, MBIT, BBIT, OIT, and DCOIT) in consumer products and their emissions was developed and validated according to ISO/IEC 17025.

Characterization of VOC and formaldehyde emissions from a wood based panel: results from an inter-laboratory comparison.

Six European laboratories used the emission test chamber method (EN ISO 16000-9) for the determination of VOC and formaldehyde emissions from a wood based panel (particleboard). The tested panel was conditioned without wrapping over 28 d at 23 degrees C and 50% RH before shipping to each participating laboratory. Emission chamber testing was carried out with air sampling after 3 and 28 d.
