New Analyser for Particle Size, Shape & Concentration Measurement


Fully Automated AOX/TOX Column Preparation and Introduction


TE Instruments (the Netherlands) presents the TUSCAN, an AOX/TOX column auto sampler with 42 positions. Combining the column auto sampler with the XPREP-A series results in an exceptional high- throughput system. Due to fully automated column preparation and introduction, the analysis runs practically unattended.


The XPREP-A series is the fastest column sample preparation system in today’s market. Specially designed to meet international standards like ISO, EPA and DIN methods (e.g. ISO 9562, EPA 9020). It automatically runs 100 mL water samples over the AOX/TOX columns at controlled sample flow of 3mL/min. Once the water sample has passed through the columns a wash cycle automatically starts, which removes the inorganic load from the surface of the activated carbon. The complete process is fully controlled by TEIS Software.


The EyeTech (the Netherlands) Particle Size and Shape Analyser combines two technologies to measure particle size and shape using Laser Obscuration Time (LOT) and Dynamic Shape Analysis. Real time video ensures “Seeing is Believing“. All automated through powerful Windows 8.1 software with numerous features to make your life easy. The versatile EyeTech is fully equipped to meet any environmental particle-application requirement like flocculation-dynamics in waste-water treatment plants, oildroplets in water, tap or waste-water, membrane filtration or sedimentation (sand, silt, clay) studies. This direct measurement gives high resolution, can even handle high and low concentrations, bimodal distributions! Transparent, shiny, non-spherical particles are no problem as also minor fractions will be detected. No need for Refractive- and or Absorbance Index. No need for calibration. 40 ISO shape parameters. Particerange o,1-3000 micron. Suitable for Temperature and Kinetic studies! Beyond the limits of laser diffraction!

New HPLC Columns: The Reliable Cornerstone for Your LC Lab


Solid, reliable Roc HPLC columns from Restek (USA) are pressure rated for any 400 bar HPLC system and deliver


the peak shape, reproducibility, ruggedness, and performance you demand for all of your conventional HPLC applications. An exceptional value for routine analyses and large-volume workflows, Roc columns are made from high- purity silica backed by quality manufacturing and are available in a variety of phases. And newly designed minimal packaging offers compact storage with serial #-specific certificates of analysis available for download at Restek’s website.


These rugged new columns are built to give you dependable data for a wide range of everyday methods. Roc HPLC columns are available with C18, C8, Phenyl-Hexyl, Cyano, and bare silica phases on either 3 or 5 µm fully porous spherical particles. Choose 3.0 or 4.6 mm ID in 100, 150, or 250 mm lengths for coverage of 98% of USP methods.

Running the analysis, practically unattended, has become the new reality. Up to 42 columns can be loaded into the TUSCAN column auto sampler. A full run will take approximately 6-7 hours. While the XPLORER is analysing, fresh columns can be prepared with the XPREP-A6 again. This takes only 45 minutes for 12 columns, and provides the user enough time to refill the column auto sampler before the next run.


For high demanding laboratories, TE Instruments offer the XPREP-A12. With the XPREP-A12 a laboratory can double its sample pre-treatment capacity allowing an even higher sample throughput. This column pre-treatment system is capable of producing enough columns to feed two combustion analysers full throttle on a 24/7 basis.

Breakthrough in EOX (PCB) Analysis

Fast and Accurate analysis of Extractable Organic Halogens and especially the PCB’s (Poly Chlorinated Biphenyls) problematic? Discover the TE Instruments XPLORER Series’ Hybrid Introduction Module. The challenge of measuring PCB’s accurate and efficient is over!


TE Instruments presents a new liquids introduction module to introduce EOX samples, the Hybrid Introduction Module. The direct vertical injection into the liquids module completely eliminates the requirement for a boat analysis together with its long analysis time. Better controlled injections and larger injection volumes provide a higher accuracy, a lower detection limit and superior analysis time. The design of the Hybrid liquids introduction module ensure optimal combustion of PCB samples with high boiling components.


Each TE Instruments XPLORER has a standard built-in semi-automatic syringe drive, which


offers full control over the injection rate and sample volume. For high demanding laboratories, TE Instruments provides the module as a fully automatic configuration together with the ARCHIE liquids auto sampler. The strong combination between introduction module and auto sampler saves time and reduces errors. Changing from semi-automatic to fully automatic injection in a later stage is done in a matter of minutes, no adjustments need to be made.
