  Invitation to YMC Every two years the leaders in preparative chromatography meet for the Symposium on Preparative and Industrial Chromatography and Allied Techniques (SPICA). As a supplier strongly rooted in preparative chromatography, YMC will participate in two ways:

 

  Connectivity and Compatibility of Kronlab laboratory glass columns Sometimes one does not see the woods from the trees – or in other words: for some people it is evident, but not so for the others. With regards to Kronlab glass columns there are two questions still frequently asked..

 

  Glass columns In the laboratory glass columns are favoured by many chromatographers because of their inertness towards proteins. Also the possibility to clean the packed columns with highly alkaline caustic soda solutions, a widely-used purification step, is a good argument for glass columns.

 

  Binary prep. HPLC-system for processing large volumes of ureacontaining protein solutions Often client specific requirements for multipurpose equipment can not be solved with “off the shelf“ solutions. In this specific case, the Kronlab custom build approach proved very useful: every component has been specifically approved for the application at hand and following a specified procedure it is integrated into an LC system. The result is a made-to-measure system.

 

  NEW: YMC-Triart Multi-layered hybrid material for HPLC

 

  YMC Europe GmbH at Analytica 2010 in Munich Analytica 2010 is taking place from the 23rd to 27th of March in Munich, Germany and YMC will be taking part.

 

  New YMC microreactor Systems Microreactor technology, is currently one of the most innovative techniques in the field of chemical synthesis and similar fields. Now specific microreactors are coming to laboratories. Scientific advances throughout the world have demonstrated the many advantages which can be achieved through the use of microreactors for chemical reactions and processes.

 

  Binary Prep LC System for isolation of components from human blood serum Customised requirements for GMP-conforming extraction of substances are often not satisfied by “off-the-shelf” solutions. Every component in the well-established modular systems from Kronlab meets the requirements which will be demanded by the customers’ needs for an established procedure. The result: A made-to-measure system

 

  Workshop: Preparative liquid chromatography Run at our laboratory facilities in Dinslaken, Germany, this hands-on course is designed to introduce both theory and practical concepts of preparative liquid chromatography.

 

  Scalable and pH stable: New C8 and C18 hybrid phases from YMC

 

  HPLC-Tip: Degassing of the mobile phase A released gas in mobile phases during analysis causes noisy baselines and pressure fluctuations which affect sensitivity and reproducibility. It also severely compromises the use of fluorescence-, refractive-index- or UV-detectors (particularly at wavelengths below 210 nm). As a consequence effective mobile phase degassing must be employed for many analyses.

 

  The Bio-Chromatographers Simply high dynamic binding capacities (DBC’s) are no longer sufficient. High DBC, at high flow rates with close to 100% recovery, across a wide range of molecular weights, this is what chromatographers look for in modern ion exchange resins. “BioPro” YMC’s hugely successful ion exchange material offers exactly this. The growing user base confirms very good separation, high dynamic binding capacities and excellent recoveries for the anion as well as the cation exchanger material.

 

  New: YMC-Triart C18 With YMC-Triart challenging pH-Stability and high temperatures are no longer a limitation to your work.
Above all due to its unique particle composition a balanced hydrophibicty and silanol activity are achieved which makes YMC-Triart a “First Choice” column in method development!

 

  Ion Exchange Media for High Resolution Purifications of Biomolecules YMC-BioPro Q30 and S30 are high performance ion exchange resins designed for the purification of proteins, peptides, antibodies and oligonucleotides in laboratory and industrial scale.

 

  Preheating of mobile phases - "nice-to-have" or "need-to-have"? Controlling the temperature of a column is a prerequisite for reproducible results in HPLC.
Column ovens are part of most HPLC systems and many of them offer space even for semi preparative columns. But with increasing inner diameter the heat transfer from the air surrounding the column to the whole cross section of the column (filled with the cold mobile phase) becomes more and more difficult. This may result in bad peak shapes, as the radial temperature gradientcauses different separation conditions for every part of the sample depending on its distance to the outer diameter.

 

  New method development tool for Bio-LC

As chromatographers, we all know the problems during method development - “Which phase is suitable and allows a simple and robust separation?” In the field of biochromatography, phase selection is a key to success!

 

  YMC-BioPro: IEX columns for peptides, proteins and biomolecules

Are you looking for a new ion exchange material?

  Ultra Fast LC for Peptide mapping In order to succeed in developing protein-based drugs, a fast and easy detection of alteration within the protein structure is necessary. In many cases, peptide mapping is the method of choice, where proteins are analysed after digestion.

 

  New: YMC The new YMC-UltraHT brochure from YMC includes information on how to transfer methods form existing, conventional methods to ultra fast LC, without generating excessive backpressure and without the need of specialised ultra high pressure chromatography equipment.

 

  Fast routine analysis of alkaloids

The method transfer from a conventional column to an ultra fast analysis for alkaloids has shown that the use of YMC-UltraHT 2 µm column and adjustment of flow parameters for the smaller column dimensions can reduce the analyses time by about 85% accompany with significant solvent savings and significant solvent savings whilst increasing the sample throughput in the laboratory.

 

 

  HPLC hint: The advantage of premixed solvents in HPLC For several reasons the storage of 100% pure solvents in the reservoir bottles of an HPLC system can be a problem. Pure acetonitrile, in particular, affects the system by adsorption of polymers from transmission lines resulting in sticky surfaces that inhibit the opening and closing of the valves

 

  Simultaneous separation of pesticides by LC/MS With the constantly rising population and frequent uncertain weather, the need for high yielding agriculture is paramount. This means that use of plant protection agents, such as herbicides and insecticides is necessary, in order to secure harvests.

 

  Normal Phase Chromatography Normal phase chromatography is not very popular with most analytical HPLC users. Poor reproducebility of the results is often cited as an argument against normal phase chromatography.

 

  Ion Exchange Material for Capture and Intermediate Purification Applications The Ion Exchange capture material is based on the same hydrophilic polymer matrix already used for the successful analytical phase. Analytical BioPro columns (particle size: 5 μm, pore size 100 nm) have proven to show low non specific binding and high dynamic binding capacity.

 

  Facing the challenge of efficiency in bio-pharmaceutical industry With continuously increasing volumetric productivity in fermentation processes, new stationary phases can help to overcome shortcomings in downstream processing. In order to address this YMC has developed a new Ion Exchange resin with high dynamic binding capacity and low nonspecific interaction. This helps to reduce “cost of goods” in the production process.

 

  FastLC Application for Curcumin The plant pigment curcumin, found in the popular Indian curry spice turmeric, is well known as an antioxidant for foods. However, researches have paid attention to another characteristic. Curcumin is highly active against the growth of certain cancers.

 

  YMC Exphere - Takes the Pressure off Preparative LC

YMC is pleased to introduce Exphere, a new family of bulk packing materials, specifically designed for preparative liquid chromatography. Exphere combines YMC's novel high strength silica with a special polymeric surface modification technique.

 

  Melamine in pet-food Melamine (sometimes confused with the plant and animal compound, melanine or another compound, melanin) is an industrial chemical used in the manufacture of plastic products. Despite that, tests showed that a number of milk companies have used it in processing milk to artificially increase the apparent protein content by addition of non-protein nitrogen and so allowing illegal dilution of the product with water with a corresponding increase in sales value.
