Flash chromatography is a purification technique that is designed for rapid separation by using air pressure as opposed to slow and inefficient gravityfed chromatography. It differs from the conventional column technique by using slightly smaller silica gel particles and pressurized gas at 50–200 psi.
Extraction Techniques for Environmental Samples
July 1st 2006Because most samples are usually unsuitable for direct analysis, extraction is perhaps one of the most important sample preparation techniques for environmental samples. The most common types of extraction techniques include solid phase extraction (SPE), Soxhlett/liquid?liquid extraction (LLE), and advanced extraction techniques. The method used for a particular application depends on the nature of a sample.
Market Profile: Pharmaceutical Market Demand for Life Science Instrumentation
May 1st 2006Globally, 2005 sales of pharmaceuticals have been estimated at approximately $550 billion. A significant fraction of this amount was due to the top pharmaceutical companies in the world. The top five companies alone were responsible for total revenues of $168 billion, or 30% of the entire market.
Market Profile: Life Science Research
April 1st 2006Without a doubt, life science technologies are providing valuable information and have become the core that discovery relies upon. Life science instruments are used predominantly by four industrial segments, which include academia, biotechnology, government, and pharmaceutical research labs. Due to the amount of money being spent, these industrial segments are under pressure to deliver exciting new discoveries.
