Suppressor Module for Anion Chromatography
Suppression plays a key role in ion-exchange chromatography and conductivity detection. It is widely used, e.g., for the analysis of anions and organic acids. Metrohm is pleased to present a new brochure putting the theoretical aspects and practical benefits of suppression in ion chromatography in a nutshell.
Suppression as a practical solution for ion chromatography: decreases the background conductivity of the eluent; minimises baseline noise; optimises the signal-to-noise ratio; increases the sensitivity of the measuring system.
To this date, the Metrohm Suppressor Module (MSM) is the most efficient and robust technical solution to implement suppression in ion chromatography. The patented MSM consists of a small rotor containing three cartridges filled with cation exchanger resin. While the first cartridge is used for suppression, a regeneration step is performed on the second cartridge. The third cartridge is rinsed automatically during this time. Hence, with each
shifting of the rotor, a freshly regenerated suppressor cartridge is always available for every new sample.
The practical benefits of the MSM are striking: due to the excellent signal-to-noise ratio, anions and organic acids can be determined down to the ultratrace range; measurements can be started just half an hour after switching the IC system on; applications can be changed at any time with no impact on system performance; due to the robust design and the working principle of the MSM, the MSM comes with a 10 year warranty. In practice this means that it is bought once with the IC system and will never have to be replaced.
31236pr@reply-direct.com Product for High Resolution SFC or HPLC Chiral Separations Launched
ES Industries is launching ChromegaChiral CCC™ a new product for high resolution chiral separations and purification by super critical fluid chromatography (SFC) or high performance liquid chromatography (HPLC), available in bulk or packed columns, the new standard for difficult separations and purifications.
“Having listened to the comments of separation scientists with difficult enantiomeric separations, we wanted to create a solution that was selectively different, rugged, and reproducible for separations that are not obtained easily using other chiral stationary phases,” said David Kohler, President. “ES Industries and ChromegaChiral are well-known and respected chromatography brands, and we felt the time was right to extend our offering to provide our customers with a solution for enantiomeric mixtures that are difficult to separate limiting their characterisation by SFC and HPLC.”
“By design, ChromegaChiral CCC media, based upon modified cellulose coated on ultra-high purity metal free silica, is proven to provide alternative and complementary separations for many enantiomers,“ noted Vice President and Technical Director Dr. Matthew Przybyciel. “The use of cellulose modified with chlorinated phenyl group moieties provides for the separation for many previously unresolved/poorly resolved chiral mixtures.”
ChromegaChiral CCC™ is offered in bulk with particle sizes from 3 to 20 micron and in packed columns from capillary to preparative.

High Vacuum Benchtop Solvent Evaporator
The EZ-2 Elite Centrifugal Evaporator from Genevac has been designed to provide unmatched final drying of stubborn samples and fast lyophilisation of HPLC fractions. Benefiting from a high performance scroll pump, that delivers deep vacuum, the EZ-2 Elite is able to routinely remove even very high boiling solvents such as DMSO and NMP. In addition internal heating of vapour duct and system components ensures that such challenging solvents only collect in the SpeedTrap™ condensor, and not anywhere else. The SpeedTrap condenser on the EZ-2 Elite comes the benefit of automatic defrost and drain technology. The EZ-2 controls the SpeedTrap and the Elite solvent collection vessel offering mid-method defrosting and draining. Using the EZ-2 Elite SpeedTrap, the Genevac LyoSpeed™ method of fast lyophilisation of HPLC fractions is possible on an EZ-2 Evaporator.
The EZ-2 Elite is able to concentrate or completely dry samples. The system is compatible with a wide selection of sample holders enabling evaporation from most common sample container formats including round-bottom flasks up to 500ml, tubes up to 160mm long, custom reaction blocks as well as shallow and deep-well microplates. To meet the need of the many life science companies switching their compound generation programmes from serial chemistry to parallel synthesis, the EZ-2 Elite is also able to take tubes, flasks and vials directly from the synthesis process, eliminating a manual handling step, increasing recoveries and removing the chance of cross contamination.
Running the EZ-2 Elite is highly intuitive. Just load your samples, select maximum safe temperature for samples, select solvent type and hit start. Offering true unattended operation capability the EZ-2 Elite requires no user training, even a beginner can competently use the system within 5 minutes.
