DETERMINATION OF MERCURY (Hg), ARSENIC (As), SELENIUM (Se), ANTIMONY (Sb) AND BISMUTH IN CLINICAL SAMPLES USING ATOMIC FLUORESCENCE SPECTROMETRY

The determination of toxic metals Hg, As and Sb in biological samples of humans is an important clinical screening procedure. Exposure of these metals from the diet, local surroundings and industrial & occupational processes can lead to serious and significant health issues.
Analyzing the total concentration of these elements is important but, by no means, the whole story.

USING ATOMIC FLUORESCENCE SPECTROMETRY FOR THE DETERMINATION OF MERCURY (Hg), ARSENIC (As), SELENIUM (Se), ANTIMONY (Sb) IN ENVIRONMENTAL SAMPLES

Soils are the major sink of these metal contaminants, while in aquatic systems, sediments are the major recipients for these pollutants. With the addition of analyte separation capabilities (which is becoming more routine) allowing for speciation studies, PSA offers powerful analytical tools to help contract laboratories, research teams and regulators alike with these determinations.

USING ATOMIC FLUORESCENCE SPECTROMETRY FOR THE DETERMINATION OF MERCURY, ARSENIC, SELENIUM & ANTIMONY FROM FOOD, FEED AND BEVERAGE SAMPLES

The consumption of food and drink is one of the main sources of exposure to toxic metals. Selenium, is an essential nutritional element and is often added as a supplement
to food for health benefits. It is also an important element in animal feed to ensure livestock wellbeing. Coupling Atomic Fluorescence Spectrometry (AFS) with either cold vapour generation or hydride generation has been PSA’s core
competency for over 35 years.

BASIC PRINCIPLES OF LASER DIFFRACTION AND HOW TO SELECT LASER DIFFRACTION PARTICLE SIZE ANALYZER

At its very most basic, laser diffraction is about the relationship between particle size and the angle and intensity of scattered light. Light scatters more intensely and at smaller angles off of large particles than small particles.
