  • calculate
  • Helium Pycnometry is used to calculate a materials bulk (or skeletal) density by measuring the volume of He displaced by a material inside a chamber, against that of a highly accurate calibration standard (and by knowing the mass). (warwick.ac.uk)
  • analysis

  • Specifically the technique has been adopted for use in the oil industry for detection of hydrocarbon composition in oil wells and pipeline monitoring. (wikipedia.org)
  • chromatography
  • Typically, when an aqueous solution is used to transport the sample through the column, the technique is known as gel-filtration chromatography, versus the name gel permeation chromatography, which is used when an organic solvent is used as a mobile phase. (wikipedia.org)
  • field
  • Either technique should not be confused with gel electrophoresis, where an electric field is used to "pull" or "push" molecules through the gel depending on their electrical charges. (wikipedia.org)
  • high
  • The high R 2 value suggests that two techniques are measuring the same underlying reality, but ADMIXTURE produces lower West Eurasian admixture (by about 38%) over the technique of Reich et al. (blogspot.com)
