Isocyanates are a group of highly reactive compounds which contain the NCO group. They are commonly found in many glues and spray paints. Even brief or low level exposure to these compounds has been implicated as a cause of occupational skin disease. This is because once sensitization occurs further ...

The development of a method for imaging the distribution of mesotrione and azoxystrobin in the plant after foliar uptake is described. MALDI-TOF-MS images have been obtained using an Applied Biosystems/MDS Sciex Q-star pulsar i fitted with an orthogonal MALDI source and an Nd:YaG laser. Solutions of ...

MDHS 25/3 was developed for the analysis of the most common di-isocyanates and as routinely used will probably not be able to determine the "light" NCO. The work presented here describes the extension of MDHS 25/3 to include the use of triple quadrupole mass spectro-metric detection (MS) so enabling ...

Polycyclic aromatic hydrocarbons (PAHs) are examples of hydrophobic organic contaminants (HOCs) which are widely distributed in soil and sediment in areas around the world where fossil fuel combustion and related activities have been and remain important sources.
It is widely acknowledged that PAHs ...

Drug contamination in sports supplements can lead to athletes testing positive for banned substances in urine tests. These contaminants can come from a range of sources but are not noted on the ingredient lists of the supplements. HFL offers a screening service designed to help nutritional and sports ...

The selectivity of the HPLC-MS/MS technique has enabled the determination of a wide range of dyes in complex foods and ingredients, in a single analysis. Considerable suppression of response (“matrix effects”) was observed when analysing such complex extracts so ensuring good quantification and confirmation ...

A new chemical ionisation mass spectrometer based on a proton transfer reactor (PTR) and a time-of-flight mass spectrometer (TOF-MS) is described. The resulting instrument, the PTR-TOF-MS, has some analytical features that make it very suitable for analytical applications where real time analysis of ...

This paper represents the results of a study examining the extent to which anthropomorphic environmental contamination has led to contamination of food and dietary intake of perfluorochemicals. An analytical method was developed for the measurement of perfluorooctanesulfonic acid (PFOS) perfluorooctanoic ...
