Diandree completed her PhD in Chemical and Process Engineering at the University of Canterbury in 2014.

Prior to that, she worked as a research scientist at two large research institutes (Mintek and Anglo Research) in South Africa, where she carried out investigations in the fields of extractive metallurgy and gold catalysis.

Diandree joined Syft as an Applications Scientist in 2014, and currently leads the sales team specializing in consumer, food, and environmental applications.

The impact of airborne particulates on health has been well-established, with volatile and semi-volatile compounds associated with particulate matter known to be contributing factors. However, proper understanding of the mechanisms behind the health effects of particulate matter is complicated by gas-particle partitioning and a lack of appropriate analytical techniques.

A recent collaboration between Syft Technologies, City University of Hong Kong and Guyline Asia, resulted in the first Selected Ion Flow Tube Mass Spectrometry – SIFT-MS application for aerosol analysis being introduced at the 13th annual Australia and New Zealand Aerosol Assembly (ANZAA) last month. The results of the real-time SIFT-MS analysis of desorbed volatiles from particulates absorbed on quartz filters, were presented by Dr Zhi Ning of City University of Hong Kong. This was achieved by means of coupling a Swab Desorber inlet system to the SIFT-MS instrument. The measurement of more than 20 VOCs and SVOCs, including inorganics, with analysis times of less than a minute, was demonstrated.

This promising initial study has enormous potential to further the understanding of the composition of particulate matter and its impact on human health.
