To meet the criterion of the spectrometric
method (NIEA W419.51A), two folds of the absorbance at 275 nm have to be smaller than 10% of the absorbance at 220 nm; otherwise, the matrix interference is too big to be omitted.
The obtained airborne magnetic and gamma ray spectrometric
data were reduced, assembled and finally presented in the form of contour and composite maps at a scale of 1:50.000.
Zero- and First-Order Derivative UV Spectrometric
Selected reaction monitoring-mass spectrometric
immunoassay responsive to parathyroid hormone and related variants.
3 shows the spectrometric
profile of pectin ARA 105 composition.
FACT--AOAP laboratories perform spectrometric
elemental wear metal analysis and physical property testing to determine the presence of abnormal wear metal particles and the lubricants serviceability at the time of analysis.
Airborne gamma-ray spectrometric
(AGRS) surveys provide valuable, systematic coverage of large areas, whereas ground gamma-ray spectrometry (GGRS) greatly improves the resolution of individual radioactive element sources.
"We need to simulate different possible Jupiter atmospheres in a lab so we can discover what spectrometric
signals they give," says Simon-Miller.
Otherwise, in the current proteomics--where proteins are identified primarily by correlation of mass spectrometric
data to sequence in a database, rather than de novo as during the age of chemical sequencing by Edman chemistry--there is great leeway for misinterpretation of proteomic data.
Sensitive methods for monitoring lead in environmental, clinical, and biological samples usually involve either atomic emission, absorption, or mass spectrometric
SRM 1727 is sold in solid form (a block 30 mm on each side) for spectrometric
analysis and may be chipped for use with chemical methods of analysis.
Evershed of the University of Bristol in England, employed a recently developed mass spectrometric
technique to identify milk fats on pots from the ancient sites, which range from about 1,500 to 6,000 years old.
