Microanalysis of fractions of a cubic millimeter of gas.
The method here described permits the sampling, transfer, and deter mination of respiratory gases in approximately 0.35 cmm. samples with errors not greater than ~0.2 volume per cent and in 0.07 c.mm. samples with errors not greater than ~0.5 volume per cent. It will handle up to 100 per cent absorbable gases. The analysis takes 4 to 6 minutes. The method is useful in general when only a minute...
متن کاملElectron microscopic microanalysis of bronchoalveolar lavage: a way to identify exposure to silica and silicate dust.
OBJECTIVES The diagnostic implications of finding non-fibrous inorganic particles in bronchoalveolar lavage (BAL) fluid has not been fully assessed. The aim of this study has been to measure the silica and non-fibrous silicates in BAL fluid from populations with different exposures to inorganic dust, and to find whether such measurement is useful for diagnostic purposes. MATERIALS AND METHODS...
متن کاملIdentification of thorium dioxide in human liver cells by electron microscopic x-ray microanalysis.
Thirty-two years after injection of thorium dioxide (Thorotrast) for diagnostic x-ray studies in a female patient deposits were found by light microscopy in the liver macrophages (Kupffer cells). They were shown by electron microscopy to be located inside secondary lysosomes, and by autoradiography and x-ray microanalysis they were identified as thorium.
متن کاملHigh‐throughput microanalysis of large lignocellulosic sample sets by pyrolysis‐gas chromatography/mass spectrometry
High-throughput analytical techniques to assess the chemistry of lignocellulosic plant material are crucial to plant cell wall research. We have established an analytical platform for this purpose and demonstrated its usefulness with two applications. The system is based on analytical pyrolysis, coupled to gas chromatography-mass spectrometry a technique particularly suited for analysis of lign...
متن کاملMicromachined oxygen gas sensors for microscopic energy consumption measurement systems.
Although the indirect calorimeter is a useful tool, its size and expense mean that it is seldom used in hospitals. Furthermore, its flow-through measurement technique dilutes respiratory variations, so they can only be detected with some form of high-precision instrumentation. This study employs MEMS techniques to develop an oxygen sensor as one part of a microscopic energy consumption measurem...
