摘要:
A compact, portable or handheld device for measurement of breath VOCs such as acetone is described, which incorporates a flow measurement sensor, a mini preconcentrator unit and an spectroscopy unit, such as a cavity-enhanced absorption spectrometer. The preconcentrator includes a chemically selective material to trap VOCs, which is supported on a metal foam. The apparatus is suitable for measuring sub ppm levels of breath VOCs such as acetone and for tracking blood ketone levels.
