14 New Automated Sample Preparation System for Dioxin and PCB Analysis Processes 3,500 Samples per Year
LCTech GmbH presented its new automated sample preparation system DEXTech™ Plus from 28 August to 2 September at Dioxin 2016 in Florence. Tedious and elaborate sample preparation makes the sample processing time and cost-intensive. When developing its new system for automated sample preparation in dioxin and PCB analysis LCTech focused on shortening the process time, increasing the fl exibility of the system, allowing easy handling, and achieving lower costs per sample.
With the system DEXTech™ Plus, LCTech as the specialist for automated sample preparation succeeded in reducing the processing time to only 35 minutes depending on the sample including conditioning and fractionation. This allows to process up to 3,500 samples per year with only one system. 4 systems in parallel achieve a sample throughput of up to 14,000 samples per year, making the system a perfect solution also for high throughput laboratories.
The 3 column system can be equipped with different ready-to-use columns depending on the analysed matrix or the requested fractions. Insertion of the columns is very simple: The columns are clicked into the system in seconds, without any tools and without screwing. Afterwards they are electrically locked (patented system).
The method set-up is done via touch-screen, where the parameters can be confi gured freely or pre-stored default methods can be selected.
After the sample vial has been placed into the system, the sample will be quantitatively loaded into the sample loop by the syringe pump. During the whole process the sample doesn’t come in contact with the syringe pump at any time. Due to that, as well as for the systemic rinsing of the device and the exchange of the columns, cross-contamination is reliably avoided.
Various safety features like leakage sensor, overpressure control, and waste level sensor ensure the safety of the users. The locking of the columns is only possible, if the door is closed and the system operates entirely in the low voltage range. An extractor hood is not required.
DEXTech™ Plus provides an integrated USB-port for reporting and documentation and is compliant with the EPA method and European regulations.

New Chromatogram Modeler Propels Method Development Forward
New and Improved Glass Chromatography Columns The new Omnifit®
EZ glass chromatography columns from Diba Industries, Inc provide
enhanced performance for low- to mid-pressure liquid chromatography or flow chemistry applications. With improvements based on surveys with thousands of lab technicians, the columns are redesigned from conventional Omnifit columns for easier use and more versatility.
EZ columns’ redesigned end pieces allow easier assembly, and improved ergonomics simplify height adjustment of the threaded adjustable plungers. PEEK™ column tube threads won’t chip or break, and upgraded anti-roll features prevent accidental breakage. Omnifit EZ columns are available in new sizes, including 5mm ID in a range of lengths, and 33cm lengths for all ID sizes. The fittings kit was enhanced to include Diba’s patented Click-N-Seal® conical port connections to ensure the correct torque is always applied.
fitting for 10-32
EZ columns maintain many of the same popular features of conventional Omnifit chromatography columns. Precision borosilicate glass provides inertness, visibility and performance. Fixed or adjustable PTFE end pieces include dual o-rings for a secure seal. Superior frit placement ensures bed support and even distribution of sample flow.
EZ columns are manufactured by Diba Industries, Inc and distributed globally through Kinesis Inc.
Restek’s (USA) new and improved EZGC chromatogram modeler is still free and just as simple to use as the original software, but it now offers advanced options for selecting phases, changing carrier gases and control parameters, further optimising results, and much more. The software has been updated based on user feedback, allowing chromatographers to develop and optimise GC methods more effi ciently and effectively than ever before.
The new Pro EZGC chromatogram modeler allows you to do the following: Start with either the column you have or a column recommended by the program, select compounds from Restek’s libraries or bring your own list, target specifi c compounds for resolution, alter the GC conditions to optimise your model quickly and easily, repeatedly refi ne the temperature program, switch carrier gases, change the control method, view elution temperatures in the peak list, and see results for multiple phases.
This free, online software provides a customised, interactive model chromatogram that matches real-world chromatograms with exceptional accuracy. Users can zoom in, view chemical structures, and even overlay the mass spectra of coeluting compounds. The updated Pro EZGC chromatogram modeler is an easy, risk- free way to increase lab productivity through faster, more effective method development and optimisation.

Asynt has introduced GasTrap gas purifi ers for analytical laboratories using Gas Chromatography (GC), High Performance Liquid Chromatography (HPLC) or Mass Spectrometry (GC/MS) instrumentation.
Gas purity is essential in any GC, HPLC or GC/MS application requiring high sensitivity. Available in optimised models for Helium, Hydrogen, Nitrogen and pure air, GasTrap gas purifi ers dramatically reduce the levels of contaminants, enhance the purity of lower grade helium, and help ensure instrument stability, reproducibility as well as lowering running costs.
Laboratory gases for GC, HPLC and GC/MS are typically supplied in pressurised cylinders that contain trace impurities. Even with speciality high purity gas supplies trace contaminants of up to 20ppm Oxygen, water, Carbon Dioxide, Neon and Argon are present which increase proportionately as the cylinder pressure drops.
Unlike disposable gas fi lters that are time consuming, costly and cannot remove gases such as Neon, Argon or Nitrogen, based upon patented Pressure Swing Adsorption (PSA) technology, GasTrap gas purifi ers remove all of contaminant trace gases and self-clean every cycle.
Operated via intuitive touchscreen software, GasTrap gas purifi ers can save you up to £2000.00 per Gas Chromatograph thereby effectively paying for itself within six months. In addition, disposal of fi lters is dramatically reduced and using a GasTrap gas purifi er, labs can save money through using lower grade gases. GasTrap gas purifi ers have been designed to operate
automatically for 10 years with no servicing or consumables required. For further information please visit
