Progress in direct solid sampling analysis using line source and high-resolution continuum source electrothermal atomic absorption spectrometry
(2007)
The literature about direct solid sample analysis of the past 10–15 years using electrothermal atomic absorption spectrometry has been reviewed. It was found that in the vast majority of publications aqueous standards were ...
Adaptive Background Compensation of Frequency Interleaved DACs with Application to Coherent Optical Transceivers
(Institute of Electrical and Electronics Engineers, 2021-03)
Digital-to-analog converters (DACs) with bandwidths larger than 70 GHz and sampling rates in excess of 170 GS/s will soon be required in ultra-high speed communication applications such as coherent optical transceivers ...
Relevant information of concomitants obtained from background signal using thermospray flame furnace atomic absorption spectrometry (TS-FF-AAS) and chemometric tools
(Royal Soc ChemistryCambridgeInglaterra, 2009)
IUPAC-consistent approach to the limit of detection in partial least-squares calibration
(American Chemical Society, 2014-08)
There is currently no well-defined procedure for providing the limit of detection (LOD) in multivariate calibration. Defining an estimator for the LOD in this scenario has shown to be more complex than intuitively extending ...
The long-term stability of portable spirometers used in a multinational study of the prevalence of chronic obstructive pulmonary disease
(DAEDALUS ENTERPRISES INC, 2006)
BACKGROUND: We report the performance of an ultrasound-based portable spirometer (EasyOne) used in a population-based survey of the prevalence of chronic obstructive pulmonary disease, conducted in 5 Latin American cities: ...
Calibration aspects of the JEM-EUSO mission
(Springer, 2015-11)
he JEM-EUSO telescope will be, after calibration, a very accurate instrument which yields the number of received photons from the number of measured photo-electrons. The project is in phase A (demonstration of the concept) ...
Science based calibration for the extraction of 'analyte-specific' HPLC-DAD chromatograms in environmental analysis
(Elsevier Science, 2011-01)
Multivariate science based calibration (SBC) has been applied to the resolution of overlapped peaks in liquid chromatography with diode array detection (LC-DAD). Complex river water samples spiked with 11 pharmaceutical ...
