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.Read More
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.
ONLINE WASTEWATER ANALYSIS FOR THE DETERMINATION OF MERCURY(Hg), ARSENIC (As), SELENIUM (Se) AND ANTIMONY (Sb) USING ATOMIC FLUORESCENCE SPECTROMETRY
In recent years wastewater treatment plants have been installing technologies to capture and remove the metals. The efficiency of these treatment processes needs to be monitored using accurate analytical systems.PS Analytical offers 2 fully automated online wastewater analysers are PSA 10.226 Online Hg and PSA 10.256 Online Excalibur (for As/Se)Read More
WHAT IS RAMAN SPECTROSCOPY?
Raman spectroscopy is a molecular analysis technique that has been adopted by industrial, forensic, environmental and research scientists to: • Identify and quantify unknown materials (e.g., Forensic evidence, art restoration) • Understand molecular structure (e.g., crystallinity, polymorphism) • Study spatial relationships between sample components (e.g., failure/defect analysis, depth profiling) Advantages of Raman Spectroscopy You may…Read More
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.Read More

WHAT IS DYNAMIC CONTACT ANGLE (DCA)?
When we talk about “Dynamic Contact Angle” (DCA), there are two quite different subjects that may be addressed:
– Time-Dependent Contact Angle (tDCA)
– Motion-Dependent Contact Angle (mDCA)
