Our annual review of new spectroscopy products introduced at Pittcon, or during the previous year.

Cement Analysis by the Pressed Powder Method on Benchtop WDXRF According to ASTM C114-11

November 02, 2016

Cement is one of the most important materials for construction. ASTM C114-11 covers chemical analysis of hydraulic cement. XRF spectrometry is used for chemical composition analysis of cement due to its simple sample preparation and high precision. This application note demonstrates quantitative analysis for Portland cement by the pressed powder method according to ASTM C114-11 on the Rigaku Supermini200, a benchtop sequential wavelength dispersive XRF spectrometer.

1631 - Zirconium on Aluminum

October 13, 2016

The measurement of zirconium (Zr) conversion coating on aluminum is demonstrated.

Characterization of the Elemental Composition of Black Pepper by ICP & ICP/MS for use as a Tool to Identify Potentially Adulterated or Contaminated Spices

September 30, 2016

Black pepper is often subject to counterfeiting and adulteration. Creating elemental profiles for an individual spice can be used as a tool to identify possible adulteration.

Gold Recovery from Used Ore by EDXRF

September 13, 2016

The measurement of gold is demonstrated in used ore material such as that from ore dumps and tailing piles. The recovery of uranium from the used ore material is also presented. The results how the Rigaku NEX DE EDXRF can achieve excellent results for monitoring and measuring the concentration of gold and other valuable elements in the recovery of used ore materials.
