The capillary is often the output of a capillary column from gas chromatography instrumentation. In this case, the capillary column provides separation (this is also known as gas chromatography mass spectrometry or GC/MS). Desorption of both solid and liquid samples is facilitated by heat as well as the vacuum of the mass spectrometer.

adsorbents derived from iron(III), aluminum, zirconium, and manganese(IV) have been reported to be effective in phosphate adsorpti on (Pan et al. , Ge nz et al. 2004, Goh et al. 2008). Among these metals, zirconium is a superior adsorbent owing to its strong surface complexing ability for phosphate and high chemical stability under acidic and

If irrigation water is high in salt content, then leaching is the only effective way to remove the salts. Blueberry plants are extremely sensitive to salt; therefore, high salt content in the soil will reduce water uptake, desiccate the plant, cause leaf burn (Figure 1), reduce yields, and diminish fruit quality.

Oct 21, · Prion diseases are considered to be transmissible. The existence of sporadic forms of prion diseases such as scrapie implies an environmental source for the infectious agent. This would suggest that under certain conditions the prion protein, the accepted agent of transmission, can survive in the environment. We have developed a novel technique to extract the prion protein from soil matrices.
