Fundamentals of Purge and Trap

The recommended setting for the system is flow rate of 40 ml/min for a period of 11 minutes for a purge volume of 440 ml. Desorb Mode The purged analytes are now trapped onto a solid sorbent.

E-mail received from MICE on 6/19/2001: The desorb times specified in SW-846 are just recommendations. You can use lower desorb times as long as method performance is not adversely affected.

Desorbing Water in Vacuum Systems: Bakeout or UV?

Desorbing Water in Vacuum Systems: Bakeout or UV? Shorter pumpdown times or lower pressures can be achieved by using either bakeout or UV energy to desorb water vapor.

Suggestions for Successful Binding Experiments

Begin the desorb procedure (under working tools). Follow the instructions. One of the desorb solutions is kept on the low shelf next to the Biacore, the other can be found on the second shelf on the door of the fridge under the Biacore computer.

Purge-and-Trap System Guide

For traps that desorb at 220 ° C or less, Teflon ® ferrules work well. When traps desorb at 240 ° C or higher, Teflon tends to shrink, and therefore leak, unless the ferrules are constantly retightened.

Fast and Efficient Volatiles Analysis by Purge and Trap GC/MS

Many laboratories choose wide bore capillary columns with jet separators when running Method 8260B because they can easily accept the high flow rates required to efficiently desorb the trap.
