"Hot plate" acid digestion

Traditional acid digestion procedures utilize a combination of concentrated acids to dissolve solid samples in preparation for elemental analyses by AA or ICP.

Microwave digestion systems

For complicated sample matrices or for samples where the volatile elements need to be preserved, microwave digestion is a preferred dissolution technique. Using a specially-designed laboratory microwave system, the temperature and pressure within each sample vessel can be monitored to ensure a proper digestion. Microwave digestion provides reproducible results while maintaining a high degree reliability and safety.

LECO - carbon and sulfur analyzer

Carbon and sulfur concentrations are determined by the use of infrared detectors following the combustion of the sample in an induction furnace.

Inductively coupled plasma - optical emission spectroscopy (ICP-OES)

ICP-OES is an analytical technique which introduces a sample to a plasma source to produce excited atoms and ions that emit electromagnetic radiation at wavelengths characteristic of an element. This technique provides a sensitive and rapid multi-element analysis for a variety of sample matrices.

Inductively coupled plasma - mass spectroscopy (ICP-MS) - NexIon 200

ICP-MS is an analytical technique which introduces a sample to a plasma source to produce singly charged ions. These ions are separated according to their mass-tocharge ratio and measured to determine elemental concentrations. This technique is highly sensitive and capable of detecting several elements at concentrations as low as one part per trillion.

Fire assay

Fire assaying is one of the oldest and most reliable methods for the quantitative analysis of gold and silver. The method is used for both ores and process products. This method is accepted as the industry standard.

Laser particle size analyzer

The particle size distribution of samples can be determined with the use of laser diffraction technology. Particles ranging from submicron to a few millimeters can be measured rapidly and accurately either as dry material or in solution.

Flame atomic absorption spectroscopy (FAAS)

FAAS is a spectroanalytical procedure for the quantitative determination of chemical elements (metals and metalloids) employing the absorption of optical radiation (light) by free atoms in the gaseous state. Metal ions in a solution are converted to atomic state by means of a flame. Light of the appropriate wavelength is supplied and the amount of light absorbed is measured against a standard curve. Typical concentrations range in the low mg/L (ppm) range.
