24 XRF Feature


Determination of Trace-level Chlorine in the Presence of Sulphur in Crude Oil , an energy dispersive XRF (EDXRF) benchtop system, has now been equipped to meet the analytical challenges of the petrochemical industry.


PANalytical (the Netherland) recently announced a new dedicated solution for the analysis of very low chlorine concentrations in crude oils. Epsilon 3XLE


Chlorine and sulphur are unwanted elements in crude oil and other petrochemical products. They can cause corrosion in the oil-processing and refinement installations and are harmful for the environment. EDXRF is widely used for the analysis of sulphur in oil; however, the simultaneous determination of very low chlorine concentrations poses an analytical challenge due to the proximity of both elements in the periodic table of the elements. PANalytical’s Epsilon 3XLE


energy dispersive X-ray fluorescence spectrometer is perfectly able to meet this challenge. The combination of a


proprietary chromium-anode tube, excellent resolution and sensitivity of the silicon drift detector and the powerful software enables the system to process high sulfur count rates and at the same time resolve possible line overlaps between chlorine and sulphur.


Crude oil samples are simply poured into disposable cups for liquid samples before being measured by the compact benchtop spectrometer. “The lower limit of quantification for chlorine in the presence of percentage levels of sulfur is below 2 mg/kg (ppm), which makes the Epsilon 3XLE


the perfect solution for this challenging task,” says Taco van der Maten,


petro segment marketing manager. “Furthermore the system caters for variable characteristics of crude oil composition thereby enabling a more robust and accurate determination of chlorine. The possibility to analyse all other relevant elements from Na to Am with similar outstanding accuracy and repeatability, makes it a valuable asset for a wide range of petrochemical applications”.

New Spectrometers Redefine ED-XRF With Exceptional New Levels of Elemental Analysis Performance


Why the S8 TIGER?


SPECTRO Analytical Instruments (Germany) have announced its new line of SPECTRO XEPOS spectrometers, representing a quantum leap in energy dispersive X-ray fluorescence (ED-XRF) technology and providing breakthrough advances in the multi-elemental analysis of major, minor, and trace element concentrations.


New developments in excitation and detection introduced with the new SPECTRO XEPOS ED-XRF spectrometers deliver outstanding sensitivity and detection limits and yield remarkable gains in precision and accuracy. The analysers excel at critical tasks from rapid screening elemental analysis for environmental and waste sampling to demanding applications in research, academia, and geological science. They support precise product quality control at-line for a variety of applications such as chemical and petrochemical


production, and the manufacture of cement, cosmetics, food, pharmaceuticals, and more.


Spectacular sensitivity: Innovations in adaptive excitation plus tube and detector technologies that dramatically improve sensitivity — often by 10´ or more — to boost precision, realise significantly lower detection levels, and deliver a fast and accurate analysis of a wide range of elements, from sodium to uranium. Enhanced with new high-count detector and tube designs, new sensitivity, and minimised backgrounds, the new analysers’ proprietary adaptive excitation technology enables exceptionally low limits of detection (LODs) for a wide range of elements.


Unparalleled precision: Unlike most ED-XRF elemental analysers, the X-ray tubes in SPECTRO XEPOS spectrometers remain powered on between measurements to prevent on/off variations from affecting readings. This ensures long-term stability, realises an exceptionally high degree of precision in elemental analysis — up to 3´ better than before, and delivers substantially improved analytical accuracy for concentrations from trace elements to major components.


Faster measurements: For operators who require speed more than utmost precision, SPECTRO XEPOS analyzers can dramatically cut measurement times, while still maintaining precision levels comparable to traditional ED-XRF spectrometers. The system’s high speed helps to achieve analyses of most samples within a few minutes.


Redesigned operating software provides proven ease and power, while the unique new TurboQuant II software quickly and accurately analyses practically any unknown liquid, powder, or solid sample. In addition, the new SPECTRO XEPOS spectrometers exhibit a significantly lower cost of ownership than wavelength dispersive X-ray fluorescence (WD-XRF) spectrometers — thus delivering WD performance at an ED price for many applications.


Optional AMECARE M2M (machine-to-machine) support extends the new analysers’ self-diagnostic functions with proactive alerts, backed up by direct connection with a remote SPECTRO service expert’s PC.


The new line of SPECTRO XEPOS ED-XRF spectrometers is available immediately from SPECTRO Analytical Instruments. Four advanced versions are available, enabling users to prioritise their selection according to measurement speed, ultimate precision, or groups of targeted elements in specific matrices.

Managers, operators and quality control personnel in the oil and gas, power generation, automotive, aerospace and metal recycling industries can now assess the chemical composition of metals with a new analyser that is smaller and lighter than any X-ray fluorescence (XRF) alloy analyser on the market today.


The Thermo Scientific (USA) Niton XL5 analyser [http://www.thermoscientific.com/en/about-us/promotions/niton-xl5-handheld-analyzer. html?ca=XL5] is designed to provide results rapidly and with a high level of accuracy. Weighing only 2.8 pounds (1.3 kilograms), the compact Niton XL5 analyser enables operators to access difficult-to-reach areas to maximise test coverage, reducing user fatigue and providing exceptionally low limits of detection (LODs). Other features include a new electronics processor that enables real-time results display and a hot-swappable battery and travel charger for improved operator efficiency in the field.

Since the initial launch of the Niton XL5 analyser in September 2015, Thermo Fisher has added an expanded precious metals element suite. Thermo Fisher designed this feature to allow precious metals foundries and refineries to increase efficiency by determining the quality of incoming raw materials and final end-products with accuracy and precision.


“Precise quality control testing of metal chemistry is becoming increasingly important, especially in the high-growth metals fabrication market,” said Mark Lessard, business development manager, portable analytical instruments, Thermo Fisher. “We designed the Niton XL5 analyser to increase user productivity and confidence while providing a powerful solution designed to help our customers achieve increased levels of quality assurance, quality control and analytical performance.”


The Niton XL5 platform provides enhanced communication capabilities through WiFi, Bluetooth and GPS connectivity. The Thermo Scientific NitonConnect companion PC software delivers easy data transfer and remote viewing functionality when the analyser is mounted on a test stand.


The Thermo Scientific Niton XL5 analyser also offers a new powerful 5W x-ray tube to provide detection of light elements and micro and macro cameras for enhanced data collection. A new user interface and display that includes a touchscreen with swiping functionality; and improved ingress protection for rugged environments has further enhanced the XL5. Additionally, customisable profiles that can be created for different applications prior to testing.
