Construction Products
Each of these regulations typically demands product testing in accordance with standard methods.
Fragrance Product
Analysis of fragranced goods is of great importance for manufacturers, whose reputation may rely upon the chemical composition of their products meeting consumer demands and regulatory requirements.
A vast range of fragranced consumer products may be monitored for their odours, including:
Profiling these products can often be a challenge, because of the presence of many VOCs at a wide range of concentrations, typically in a highly complex sample matrix.
Fragrance product analysis is currently focused on three main areas:
The ability to run a wide range of sample types is essential for profiling fragranced goods.
The use of trap-based preconcentration is also important, because it allows sensitivity for trace-level compounds to be dramatically enhanced. Moreover, systems featuring a backflushed trap enable a wider range of sorbents to be used, allowing simultaneous analysis of volatile and semi-volatile compounds from a single analytical procedure.
Plastics
Understanding the effect of manufacturing processes on emissions of volatiles from polymers is a key issue for routine product quality monitoring – for example, to check the levels of residual solvents or monomers.
Such assessments are also required for compliance with regulations such as the European CPR and REACH. However, in addition to this, there has been much regulatory attention devoted to certain chemical classes.
Chemicals of greatest concern to regulators have been those implicated in certain endocrine-related disorders. These include:
Thermal desorption is compatible with three common sampling techniques for assessing emissions from polymers:
