The LightCycler was an open platform not restricted to one fluorescence method
or probe design, setting a precedent for future instruments.
Detection of acid fast bacilli in saliva using Papanicolaou stain induced fluorescence method
versus fluorochrome staining: an evaluative study.
The cupellation method delivered accuracy, however, the x-ray fluorescence method
is also matching those accuracy levels with values of 0.1% or better, with a measurement time of less than 2 minutes.
With the fluorescence method
, we centrifuged the heparinized whole blood samples at 1,500 X g (Allegra X-22R centrifuge; Beckman Coulter, Fullerton, CA, USA) for 15 min at 4[degrees]C to isolate the plasma.
These limitations make it necessary to standardize a fluorescence method
by using some sort of volumetric device.
Using a fluorescence method
to track the bacteria, the scientists found that, during winter, the coral-infecting bacterium takes refuge in a marine fireworm, Hermodice carunculata.
A key development of the project was a matrix-independent x-ray fluorescence method
created by a NIST scientist, in which calibration standards are prepared from primary reference materials using borate fusion.
Kiyoshi Yoshikawa, Institute of Advanced Energy, Kyoto University, Japan, describes Potential Well Measurements by the Laser-Induced Fluorescence Method
in an Inertial-Electrostatic Confinement Fusion Device.
After correcting for the injection volume and dilution of the ink, the mean concentrations Of L-dopa and dopamine were obtained for each ink sac analyzed by the fluorescence method
These preliminary studies indicate that a fluorescence method
may be less ambiguous and better suited for detecting crop residues from soils than the reflectance method.
The X-ray fluorescence method
is especially economical for screening the components as a first step of the inspection process.
