A gas chromatography/mass spectrometry (GCMS) analysis of the headspace from the faeces of neonates was undertaken to record the volatiles associated with preterm babies on a neonatal unit. The compounds ethanol, acetone, 2-ethyl-1-hexanol, 3-methylb... Read More about An analysis of volatiles in the headspace of the faeces of neonates.

A sensor system for monitoring the simple gases hydrogen, carbon monoxide, hydrogen sulfide, ammonia and ethanol in exhaled breath (2008)
Journal Article

A sensor array system was constructed incorporating electrochemical sensors for hydrogen, carbon monoxide, hydrogen sulfide and ethanol, a ceramic sensor for total volatiles and a dye-based optical ammonia sensor. The system was calibrated using stan... Read More about A sensor system for monitoring the simple gases hydrogen, carbon monoxide, hydrogen sulfide, ammonia and ethanol in exhaled breath.

Detection of disease by analysis of emissions (2008)
Patent
Probert, C. S. J., & Ratcliffe, N. M. (2008). Detection of disease by analysis of emissions. 1949852

A method of determining the cause of disease is described, which method uses the detection of "signature" or "fingerprint" volatile compounds in an emission, especially flatus, from a patient.

Identification of Campylobacter infection in chickens from volatile faecal emissions (2008)
Journal Article
Garner, C. E., Smith, S., Elviss, N. C., Humphrey, T. J., White, P., Ratcliffe, N. M., & Probert, C. S. (2008). Identification of Campylobacter infection in chickens from volatile faecal emissions. Biomarkers, 13(4), 413-421. https://doi.org/10.1080/13547500801966443

Volatile organic compounds from chicken faeces were investigated as biomarkers for Campylobacter infection. Campylobacter are major poultry-borne zoonotic pathogens, colonizing the avian intestinal tract. Chicken faeces are the principal source of co...

A study of methods for evaluating the integrity of plate type heat exchangers used in the dairy industry (2007)
Journal Article
Dowman, A. A., & Ratcliffe, N. M. (2007). A study of methods for evaluating the integrity of plate type heat exchangers used in the dairy industry. International Journal of Dairy Technology, 53(1), 30-20. https://doi.org/10.1111/j.1471-0307.2000.tb02650.x

An overview of leak testing methods for heat exchangers is presented. The problems associated with the presence of residual liquid during testing were assessed as it was shown experimentally that complete drainage of plate type heat exchangers is ver...
