Future trends high volume

Electrospray in the mid 1980s revolutionized biological mass spectrometry, in particular in the field of protein and peptide sequence analysis. Electrospray is a concentration-dependent, rather than a mass-dependent process, and maximum sensitivity is achieved at low flow rates with high-concentration, low-volume samples (Griffiths 2000). Joint NMR, x-ray diffraction, electrophoresis, and chromatography techniques with mass spectrometry (MS) techniques would be a trend in the future. 

The U.S. Department of Health and Human Services also performs an annual survey of high school students to determine trends in their use of illegal substances. These annual results are published in a volume entitled Monitoring the Future. According to the most recent Monitoring the Future data, eight percent of all American tenth grade students say that they have used cocaine, and four percent say that they have tried crack. 

The variety of porous membranes, in terms of both materials and microstructures, makes them popular in different chemical reaction processes. They are applied mostly in a tubular configuration. However, the hollow fiber represents a trend for future development due to its remarkably high area/volume ratio. Table 2.5 summarizes the conventional inorganic porous membranes used in membrane reactors.
