Off-the-Shelf LIMS for Radiolabelled Environmental Studies is Released


Debra 6.1, LabLogic’s (UK) latest addition to the Debra platform, incorporates the previously standalone system Trace as part of its core functionality. This new module is aimed at solving the problems of isolation of metabolites and residues from matrices, which can be a long and complex process.


Keeping track of the extraction systems used and the calculations necessary to determine the concentration of each component in the extraction system presents a number of problems, all of which are addressed by this new module. It allows the scientist to keep track of complex extraction procedures used to isolate residues and metabolites from samples. These fractions and residues can then be analysed by the typical Debra routes of weighing/LSC counting to ensure recovery of the radioactive sample along each step of the pathway. Final analysis by radiochromatography can be performed to see the major analytes in the sample data from Laura. Chromatograms can be linked to enable reporting of recovery or concentration of these metabolites.


To aid the user further, visual representation of the extraction steps are shown in a sample tree to enable the scientist to see how the pathway of the end-product was isolated.


The key benefits of using Debra to perform this work over manual data entry into spreadsheets are the time savings and accuracy of data recorded with direct data collection from lab instrumentation as well as integration of chromatography data.


For more information about Debra 6.1 please contact Huw Loaring, LabLogic’s Systems Director, who will be pleased to demonstrate the capabilities of the the new module.

Measuring Oil Content in Off-Shore Drill Cuttings Using Portable IR Analysers


Large amounts of drill cuttings are produced in off-shore drilling and must meet an allowable limit on the amount of total petroleum hydrocarbons (TPH) they contain for ocean disposal. As an example, the North Sea currently has a 1% limit for disposal of drilling cuttings. Transporting the cuttings to shore is labour intensive, costly and could cease due to bad weather. Limit requirements also must be met for on- shore disposal or reuse. Whether on-shore or off-shore disposal, InfraCal Analysers from Wilks (USA) can verify that the oil content of the drill cuttings is below the allowable limit in less than 15 minutes.


are measured at 3.4 micrometers (2930 cm-1 specifically designed for non-technical users.


The InfraCal Analyser is a compact, fixed-filter mid-infrared analyser with no moving parts. Hydrocarbons ). The analyser is rugged and portable -- weighing less than 5 pounds -- and the user interface is


The analysis procedure involves several simple steps allowing an operator with minimal training to do the analysis. 1. The sample is collected in a container. 2. The solvent (hexane, pentane, cyclohexane, perchloroethylene or S-316) is added at a ratio of one part solvent to ten parts sample. For solids testing, the ratio is one part solids to one part sample. 3. After shaking for 2 minutes the solvent partitions and a portion of the solvent is introduced to the infrared analyser for measurement. With soil, the solids are filtered from the solvent prior to testing. 4. The complete analysis from sample collection to final result takes less than 15 minutes.

Waters Corporation (USA) recently introduced CORTECS Columns, a new family of 1.6 micron solid-core UltraPerformance LC Columns that set a new standard in LC column performance. The higher efficiency brought to chromatography with CORTECS Columns allows laboratories to produce greater amounts of information faster with every chromatographic separation.


Available in C18, C18+ or HILIC chemistries, Waters offers the columns in 30 unique column configurations and is making them available for shipping worldwide. Waters introduced the new columns at HPLC 2013, the 39th Annual Symposium on High Performance Liquid Phase Separations and Related Techniques.


The industrys most significant new column introduction in years, when used together with the low-dispersion Waters ACQUITY UPLC, ACQUITY UPLC I-Class and ACQUITY UPLC H-Class Systems, CORTECS Columns offer previously unattainable levels of performance.


With the introduction of CORTECS columns, Waters is again responding to the need of laboratories for greater resolution, speed and sensitivity, said Michael Yelle, Vice President, Consumables Business Operations, Waters Division. This family of columns represents a leap forward in chromatographic particle design, column hardware, packing technology and, most importantly, overall performance.


CORTECS Column particles feature a solid, impermeable silica core encased in a porous silica outer layer where the interactions between the stationary phase and the analytes occur. The three CORTECS chemistries and their intended uses are: CORTECS C18 Column is a general-purpose, high-efficiency, reversed-phase column offering balanced retention of acids, bases, and neutrals at low and mid-range pH; CORTECS C18+ Column is a general-purpose reversed-phase column with a positively charged surface that delivers excellent peak shape for basic compounds at low pH; CORTECS HILIC Column is designed for the retention of extremely polar analytes while offering orthogonal selectivity versus C18 columns.


The product of more than 40 years of bonding and surface technology know-how and a decade of synthesizing and packing sub-2- micron particle columns, Waters CORTECS Columns deliver the full benefit of solid-core particle technology.....

Free Professional Webinar Series for the Industrial Market Launched


Oxford Instruments Industrial Analysis (UK), a specialist global supplier of high quality instruments used for materials identification and thickness gauging analysis announced recently plans to roll out a free professional webinar series geared toward methods and techniques for X-Ray Fluorescence (XRF) and Nuclear Magnetic Resonance (NMR) analysis. For more than 30 years Oxford Instruments has been involved in manufacturing analytical system and components for both research and industry with a vision to pursue responsible development and deeper understanding of the world through science and technology.


The Oxford Instruments’ complimentary online webinars are geared toward providing effective learning and solutions for even the toughest industrial analysis applications and most complex technical dilemmas across a broad range of industries. These webinars will provide access to industry experts and contemporary application practices that can help companies to improve efficiencies, minimise risks, streamline quality control processes, and save money. Many of these laboratory and field techniques are essential practices for many companies and industrial professionals, across a wide range of industries and geographies, concerned with quality control, materials verification, supply chain management, compliance testing, and reporting. Webinars are an ideal way to learn and share important information because participants can connect with others of similar discipline from around the world and they don’t need to spend time and money to travel; the webinars can be joined from virtually any location from around the globe, and many of the archived webinars are slated to be made accessible upon demand.
