We describe an evaluation of a transportable quadrupole mass spectrometer and the modifications required for the direct measurement of trace levels of organic solvents in breath. The instrument has been used in human volunteer breath studies and has potential as a non-invasive measure of industrial
It was recently demonstrated that in a liquid scintillation spectrometer hard p-emitters (""P, 24Na, lo6Rh, 144Pr, Q"Y, 40K, \*04T1, s"Sr, 13'Cs, 42K) can be measured in aqueous solutions without the addition of scintillator (l-3). This is due to the fact that fast fl-particles in water give rise to
The development of a non-invasive prenatal diagnostic test using fetal nucleated red blood cells (NRBCs) isolated from the maternal circulation is hampered by the low frequency of these cells in maternal blood, requiring extensive enrichment procedures before any analytical procedure can be performe
