(XRF) X-Ray - Fluorescence Spectrometer
QUALITEST , are active in providing miners, jewelers, precious metal industries, research laboratories and quality control departments with the most technologically advanced testing equipment, offering the best in product quality and highest performance.
Our 15 years of research and continuous development has lead to the introduction of highly precise and top of the line range of x-ray fluorescence spectrometers. These are widely used in fields such as plating thickness, precious metals (Au, Ag, Pt, Pd, etc), electronic and electric industries. They are also applied in commodity inspection, scientific study, and RoHS detection.
XRF allows close monitoring of mining processes and of the product quality. XRF can be used to analyze the chemical and the mineral phase composition- element concentration, what elements are present, how much of each (weight %)?

FT-IR Spectrophotometers
F510/520 Series FT-IR Spectrophotometers are designed to meet the high validation standards set by QA/QC, method development and analytical service laboratories. All systems in the range offer fast throughput and rapid access to reliable and dependable FTIR results, day in and day out.
Atomic Absorption Spectrophotometers (AAS)
Atomic absorption spectroscopy (AAS) determines the presence of metals in liquid samples. Metals include Fe, Cu, Al, Pb, Ca, Zn, Cd and many more. It also measures the concentrations of metals in the samples. Typical concentrations range in the low mg/L range.
In their elemental form, metals will absorb ultraviolet light when they are excited by heat. Each metal has a characteristic wavelength that will be absorbed. The AAS instrument looks for a particular metal by focusing a beam of uv light at a specific wavelength through a flame and into a detector. The sample of interest is aspirated into the flame. If that metal is present in the sample, it will absorb some of the light, thus reducing its intensity. These instruments measure the change in intensity. A computer data system converts the change in intensity into an absorbance.

Sample Preparation Equipment for Spectroscopy
Qualitest covers a complete range of instruments for Optical emission spectrometry (OES) and X-Ray fluorescence which are most commonly used techniques for the analysis of metals and solid samples.
Sample preparation of metals and materials have become more and more important because of the rapid development and improvement of both software as well as OES and XRF-devices during the past few years that shifts the detection limit for trace analyses. It is crucial to have the sample properly prepared.
