Glass columns – not only for biochromatography
Mar 24, 2010

• 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

HPLC-Tip: Degassing of the mobile phase
Dec 23, 2009

• 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’ wish
Dec 23, 2009

• 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.

Preheating of mobile phases - "nice-to-have" or "need-to-have"?
Dec 23, 2009

• 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.

HPLC hint: The advantage of premixed solvents in HPLC
Dec 23, 2009

• 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

Melamine in pet-food
Dec 23, 2009

• 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.
