Journal Article
Boulind, C. E., Gould, O., Costello, B. D. L., Allison, J., White, P., Ewings, P., …Francis, N. K. (2022). Urinary Volatile Organic Compound Testing in Fast-Track Patients with Suspected Colorectal Cancer. Cancers, 14(9), 2127. https://doi.org/10.3390/cancers14092127

Colorectal symptoms are common but only infrequently represent serious pathology, including colorectal cancer (CRC). A large number of invasive tests are presently performed for reassurance. We investigated the feasibility of urinary volatile organic... Read More about Urinary Volatile Organic Compound Testing in Fast-Track Patients with Suspected Colorectal Cancer.

The detection of trace volatiles from complex matrices using gas chromatography mass spectrometry (GCMS) techniques and selected ion flow tube mass spectrometry (SIFT-MS) assessment of volatiles produced from nitric oxide producing smart dressings (2020)
Thesis
Gould, O. The detection of trace volatiles from complex matrices using gas chromatography mass spectrometry (GCMS) techniques and selected ion flow tube mass spectrometry (SIFT-MS) assessment of volatiles produced from nitric oxide producing smart dressings. (Thesis). University of the West of England. Retrieved from https://uwe-repository.worktribe.com/output/3807511

Volatile compounds (VCs) hold the potential to diagnose and monitor disease states in a cost effective, rapid, and most importantly non-invasive manner. Gas chromatography mass spectrometry (GC-MS) has been in use since the 1960s and remains the gold...
