The growing popularity of tattoos, especially among young adults, raises concerns about the composition of tattoo inks and any potential long-term health effects they present. The European Commission Joint Research Centre recently noted that about 12 percent of Europeans have…
PANALYTICAL says the combination of the latest excitation and detection technologies means that its upgraded Epsilon 3X benchtop X-ray fluorescence (XRF) spectrometers can match or even surp[ass the performance of more powerful instruments for the detection of light elements. The…
ELEMENTAL analysis of halogens, phosphorus, and sulphur by oxygen flask combustion can be performed safely and economically using the OFCU-1 unit, says Exeter Analytical. Oxygen flask combustion is a common preparatory step when determining bromine, chlorine, fluorine, and iodine, as…
A NEW application note demonstrating the precise determination of the carbon, hydrogen, and nitrogen (CHN) content of soil samples has been released by Exeter Analytical. This useful document includes details of the analytical methodology, used plus data demonstrating the quality…
INDUCTIVELY Coupled Plasma – Optical Emission Spectrometry (ICP-OES) is a powerful and sensitive technique employed by Warwick Analytical Service to determine total sulphur in both organic and inorganic samples. The method can be used across a broad range of sample…
A KEY factor in predicting the performance of petroleum fuels and lubricants is the percentage of carbon, hydrogen, and nitrogen (CHN) they contain. However, the volatile nature of these materials means that conventional elemental analysis is difficult to carry out.…
PURPLE Moor Grass, Molinia caerulea, is a common plant in northern Europe and is of scientific interest for the ratios of carbon and nitrogen in contains. The analysis of the material is itself straightforward, but preparing samples for analysis has…
A PROTOCOL for the direct determination of total CHN (carbon, hydrogen, nitrogen) in filter samples using the Model 440 elemental analyser has been published by Exeter Analytical. The company says using this technology to determine the percentage C, H, and…
THE CHN (carbon, hydrogen, nitrogen) elemental analyser is a mainstay of many analytical laboratories, and a new white paper from Exeter Analytical helps to throw some light on the factors affecting the performance of these instruments. Looking at the way…
