PETRO-QUANT - Quick and Easy, Accurate and Precise Quantitative Elemental Analysis of Hydrocarbons
MASS SPECTROMETRY & SPECTROSCOPY
College Spectrophotometer Investment Oberlin College continues its emphasis on the highest level of education
with its investment in top research grade spectrophotometers for its chemistry and biochemistry teaching laboratories.
Oberlin chose the Biochrom WPA Biowave II UV/Visible Spectrophotometers to teach the nation’s next generation of scientists. These Biochrom spectrophotometers enable the students to engage in the most current molecular biology, life science, and chemistry protocols, combining life science methods with rapid scanning, kinetics and concentration capabilities. Along with the highest functionality these instruments are durable, low maintenance and designed for high usage.
Oberlin College in Oberlin, Ohio is one of the United States’ premier liberal arts and sciences colleges.
The Oberlin College Chemistry and Biochemistry department prides itself in offering flexible and interdisciplinary coursework with faculty-student research, which ranges from bioorganic chemistry to atmospheric chemistry, photochemistry to catalysis research, materials chemistry to peptide structure, and cancer biochemistry to natural products research.
X-ray fluorescence analysis (XRF) is used in the hydrocarbon processing industry and related branches for trace element determination in all kind of petrochemical materials. Often a single instrument has to provide full analytical flexibility and performance for all applications in quality and process control, research and development, fulfilling future demands and decreasing limit values for regulated elements. Bruker AXS offers the WDXRF spectrometer S8 TIGER with its innovative, optimised X-ray optics and user interface matching all needs in petrochemical labs.
While the S8 TIGER’s low temperature, high-intensity X-ray tube with protective coating excites the sample even more efficiently, the combination of the tube with the shortest beam path leads to the highest possible element sensitivities. The versatile beam path and wide selection of different crystals and collimators provide advanced analytical flexibility even for the most demanding applications.
Thanks to SampleCare users in the petro chemistry can rely on the S8 TIGER 100%. SampleCare constantly protects all important system components from contamination, which might lead to incorrect results or in the worst case to system stoppage. Our S8 TIGER with SampleCare prevents this safely in 4 ways: The DuraBeryllium tube shield protect the head of the X-ray tube; the mask changer and the unique vacuum seal protect the goniometer chamber. If, by chance anything should have gone wrong during preparation, and the sample breaks or leaks out, it is not a problem. System components are well protected, easy to access and can be cleaned with little effort.

Spectrophotometer Gains New Qualifications
For the first time, Jenway’s Model 6800 spectrophotometer is available with comprehensive IQ/OQ documentation, satisfying the requirements of customers, particularly those in the pharmaceutical sector and other regulated industries.
Installation qualification documentation enables customers to ensure that they install their equipment correctly, in accordance with the manufacturer’s guidelines. Covering issues such as location of the instrument, environmental requirements, PC connection and initial set-up, the IQ document contains step-by-step instructions and provision for all stages to be recorded for audit.
Operational qualification documentation is used to verify and document that the 6800 spectrophotometer functions within the defined specification. Approved protocols using traceable standards are set out for wavelength accuracy and repeatability, photometric accuracy, as well as instructions for checking stray light, bandwidth, noise and drift.
Covering the UV/visible wavelength range from 190 to 1100nm, Model 6800 is a true double-beam spectrophotometer with highly stable optics and a 1.5nm spectral bandwidth for excellent resolution and accuracy.
All functions of the Model 6800 are controlled via a PC using Jenway’s intuitive and user-friendly Flight Deck software. The instrument’s double beam configuration compares the light absorbance of test samples with a reference sample and the comprehensive range of measurement modes includes photometrics & multi-wavelength, spectrum kinetics and quantitation. DNA/RNA ratios can be analysed to calculate the concentration of double or single-stranded DNA.
The new IQ/OQ documentation is also available separately for customers who have previously purchased a 6800 spectrophotometer. Circle no. 348
XRF Spectrometer for Advanced Materials Characterisation
Thermo Fisher Scientific, Inc announced the new Thermo Scientific ARL PERFORM’X X-ray fluorescence (XRF) spectrometer for advanced materials characterisation. The ARL PERFORM’X integrates bulk elemental analysis capabilities with mapping and small spot analysis to create a solution that offers unmatched versatility and performance for the analysis of any solid or liquid sample.
The ARL PERFORM’X is a highly precise system offering users a choice of analysed area size from 35mm to 0.5mm. As well as measuring the standard chemical composition of samples, the system facilitates elemental small spot analysis enabling analysts to pinpoint focus on specimen sections as small as 0.5 mm, significantly improving the versatility of analyses. The instrument’s advanced X-ray mapping and sample visualisation capabilities also enable users to identify and characterise inhomogeneities, such as elemental inclusions, defects and gradients in samples previously unidentifiable. The ARL PERFORM’X has the capacity to handle samples of many sizes and types including solids, liquids, powders and thin films, providing laboratories with unrivalled versatility that outperforms other solutions.
Designed for analytical laboratories in areas as diverse as geochemistry, chemical, petrochemical, materials science, contract laboratories and process control, the system’s speed, reliability and flexibility make it ideally suited to solving composition problems in demanding industrial process and quality applications. With dual sample loading the ARL PERFORM’X is able to process more than 60 samples per hour in a typical multi-element analysis case, offering rapid and precise analysis of up to 84 elements. The system also provides the highest standards of safety with an innovative sample recognition capability that ensures easy and safe loading of solids and liquids. In addition, the instrument offers unrivalled long-term stability and repeatability of results.
The ARL PERFORM’X comes as standard with the latest version of the Thermo Scientific OXSAS software. OXSAS is an easy-to-use software solution that improves productivity through its rapid and highly accurate reporting features. Users also benefit from a synoptic panel that mimics real-time operation and internal functioning of the instrument on a separate display screen enabling users to visually monitor the status of their analyses.
