Calcium was determined by atomic absorption spectroscopy with a
Perkin-Elmer Model 603 spectrophotometer (1) using an air-acetylene
flame and the 442. If it actually originated from sea salt broken apart by
ultraviolet radiation in the stratosphere, as Beckmann contended, the
ATMOS instrument and various observatories should have detected it
streaming up from the stratosphere to the mesosphere, especially since
sodium is easily detectable by absorption spectroscopy, as Beckmann
himself pointed out.
A wide variety of instrumental techniques such as infrared and
ultraviolet absorption spectroscopy, mass spectrometry, nuclear magnetic
resonance spectroscopy thermal analysis, and gel permeation and size
exclusion chromatography are useful tools in rubber analysis (ref. |
