My text doesn't provide much context, but here's a good definition of HC hang-up:
4. Does not read zero when sampling ambient air
If the hydrocarbons (HC) reading is above 20 ppm immediately following a zeroing and
the probe is not measuring vehicle exhaust, this is considered a Hydrocarbon Hangup
condition. This is caused by HC residues trapped somewhere in the sample system.

TIA!

hydrocarbon hang-up = hydrocarbon contamination
Example: "The minimum requirement to keep the sample stream clean is the use of a fine-enough, heated sample filter at the stack probe. Such filters typically are change filters from various sintered materials and need to be replaced quite often. While the stack probe filter is replaced frequently, the question is who cares about the hydrocarbon contamination (hang up) in the heated sample line (and sample probe)? May be someone sometimes, but in fact a heated line should be cleaned as often as the stack probe filter is changed. Such hydrocarbon hang-up easily becomes permanent over time and generates much higher THC readings than they are in the actual sample."
