Soil organic C was determined by dry combustion (Nelson and Sommers 1982) in a LECO high-frequency induction furnace (LECO, Saint Joseph, Michigan, USA) corrected for inorganic C using a gasometric
method (Dreimanis 1962).
open system enabling laboratory and field conditions, accurate measurement of changes in the concentration of co2 and h2o based on infrared spectroscopy and enabling the subsequent calculation of co2 assimilation rate, transpiration rate, intercellular co2 concentration and stomatal conductance of plants.
Gasometric experiments were carried out at 303 and 333 K as described in literature (Oguzie, E.
1 shows gasometric plot for the corrosion of mild steel in different concentrations of [H.
Using colorimetric and gasometric
techniques, his work influenced the practice of medicine and played a major role in guiding the direction of clinical chemistry for the remainder of the century.
Its 29 chapters covered principles of spectrophotometry, flame photometry, gasometric techniques, electrophoresis, accuracy, precision, control charts, significant figures (still abused by most authors and journals), and normal values.
Deleted in the new edition (which was intended as a supplement to the first) were gasometric techniques (including the time-honored Van Slyke apparatus), plasma and blood volumes, and thyroxine.
microdetermination of nitrates by reduction with vanadium(II).
Calcite and dolomite contents were determined by the gasometric
method of Dreimanis (1962) utilizing a Chittick apparatus.
