Split/Splitless Inlet

The most common inlet for capillary GC is known as the split/splitless inlet, which as the name suggests, can be operated in two modes, spilt or splitless. This module fully details the working principles of this inlet and the parameters that must be set for successful sample introduction. Common problems are also highlighted, ensuring you can troubleshoot or avoid them all together.
