Ashing below 150°C retains inorganics
Pyrometer shows that Tracerlab's LTA-600 can ash samples thoroughly at temperatures well below 150°C — low enough to leave all inorganic constituents u n a l t e r e d . A cold plasma of atomic oxygen does the ashing, while our accessory pyrom eter keeps you posted on the tem perature. This low-temperature dry asher permits more accurate quantitative elemental and structural analyses of plant and animal tissues, bones, coal, oil well cores, polymers, and radioactive materials. Prepares pure samples for atomic adsorption spec trophotometry, mass spectrometry, emission spectroscopy, X-ray diffrac tion, and electron microscopy.
