The DryVap® Concentrator System was intentionally designed to provide enhanced recoveries of semivolatile organic compounds, such as those found in EPA Method 8270. Its unique design of using an internal immersion heater vs. an external water bath, vacuum, and a sparge gas which is directed onto the surface of the solvent during the final stages of the evaporation process, allows the DryVap® System to achieve very good recoveries for a variety of tests.

Thin-layer chromatography (TLC) is a commonly used method development tool for flash purification. Product mixtures separated using TLC generally can be purified by flash chromatography using the identical solvent system. The method transfer accuracy of TLC to flash is based on the TLC silica and flash silica properties. When identical, the equation 1/Rf = CV holds, where Rf is the retention factor of a compound separated by TLC, and CV is the number of column volumes required to elute a compound. Cartridge loading capacity is based on the difference in CV (DCV) between two adjacent compounds.

The utilization of bound reagents for the solution phase synthesis has become an important tool in synthesis of biologically active molecules. The disadvantage of this technique is the relative slow rate of reaction. Microwave irradiation has been used to overcome this problem and increase rate of reaction of solid-assisted solution phase synthesis. This presentation covers developing efficient and robust strategies for the preparation of an array of cyclic tertiary amines using microwave irradiation in conjunction with bound reagents and scavengers such as MP-cyanoborohydride.

The crossreactivity of molecularly imprinted polymers (MIPs) and its
practical implications are discussed. Screening of MIP libraries is presented as a
fasttrack route to discovery of resins selective towards new targets, exploiting the
fact that MIPs imprinted with one type of template molecule also show recognition
to related and sometimes also to apparently unrelated molecules. Several examples
from our own and others’ studies are presented that illustrate this crossreactivity and
the pattern of recognition is discussed for selected examples.

The US EPA monitors a variety of chemicals in water that may cause harm to humans or wildlife to minimize exposure. Method 625 was developed by the Office of Science and Technology in the Clean Water program to monitor a large suite of semivolatile chemicals in wastewater for compliance with the National Pollution Discharge Elimination System (NPDES).

Safety is always a prime consideration in a laboratory. While working with organic solvents and samples that may contain harmful analytes, it makes sense to shield the operator from hazardous conditions whenever possible.
