Preparative Chiral Purifications with YMC*Gel Chiral NEA
Oct 28, 2010Chirality has become vitally important in the production of pharmaceuticals, agrochemicals and related products, due to the dramatically different pharmacology the various optical isomers can present, ranging from no activity through undesirable effects to having potentially catastrophic and sometimes life threatening adverse effects. This has led to the development of highly efficient chiral stationary phases (CSP) for analytical and preparative scale separations

Invitation to YMCâ€™s free vendor lunch seminar at SPICA
Jun 24, 2010Every 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:
Glass columns â€“ not only for biochromatography
Mar 24, 2010In 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
Mar 18, 2010Often client specific requirements for multipurpose equipment can not be solved with â€śoff the shelfâ€ś 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 microreactor Systems â€“ Microreaction technology got potential

HPLC-Tip: Degassing of the mobile phase
Dec 23, 2009A 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-Chromatographersâ€™ wish
Dec 23, 2009Simply high dynamic binding capacities (DBCâ€™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. â€śBioProâ€ť YMCâ€™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
Dec 23, 2009With 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 â€śFirst Choiceâ€ť column in method development!
Preheating of mobile phases - "nice-to-have" or "need-to-have"?
Dec 23, 2009Controlling 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.
As chromatographers, we all know the problems during method development - â€śWhich phase is suitable and allows a simple and robust separation?â€ť In the field of biochromatography, phase selection is a key to success!
Are you looking for a new ion exchange material? Have you tried the new BioPro material from YMC - it will give you a significant alternative.

Ultra Fast LC for Peptide mapping
Dec 23, 2009In 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: YMCâ€™s Applicationsbook for Ultra FastLC!
Dec 23, 2009The 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.
The method transfer from a conventional column to an ultra fast analysis for alkaloids has shown that the use of YMC-UltraHT 2 Âµm 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
Dec 23, 2009For 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
Dec 23, 2009With 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.
Facing the challenge of efficiency in bio-pharmaceutical industry
Dec 23, 2009With 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 â€ścost of goodsâ€ť in the production process.
FastLC Application for Curcumin
Dec 23, 2009The 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 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
Dec 23, 2009Melamine (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.
