This application note demontrates that the Biotage® fully automated extraction, drying and concentration systems used with the Atlantic™ HLB disk are capable of extracting PAH compounds from sea water.
Typical extraction times using the Biotage® Horizon 4790 range from 20 to 25 minutes while drying and concentration on the DryVap® with the DryDisk® took approximately 35 minutes.

In the laboratory many chemicals are used in small and larger volumes. Table 1 shows several of the typical kinds of analyses done for environmental compliance. Semivolatile organic compound extraction and evaporation can be a large source of solvent emission to the atmosphere if the solvent is allowed to go up the hood and is not recaptured.

The SolventTrap SVOC can help recover solvents evaporated during the concentration step prior to injection into the GC or HPLC.

Using a vacuum pump, the solvent vapors are pulled through a cold condenser coil, where the solvent vapors are chilled and converted back into a liquid form. The solvent then flows by gravity into a round bottom glass flask. When the flask is full a stopcock can be turned to drain the collected solvent into a disposal vessel.
Designed specifically to handle the volume of solvent vapor generated by the DryVap system, the Solvent Recovery SVOC operates at 0°C using a chiller and is capable of condensing and capturing approximately 90 to 95 % of the solvent vapor (95 % for dichloromethane (DCM)).
