English term or phrase: vent pressure
The vent pressure was reduced to 5 kPa and the split vent
was set to 100 ml/min. After 4.8 s the split valve was closed
for 1.6 min and the liner was heated at a rate of 12 ◦C/s to
280 ◦C.

ciśnienie w boczniku
Explanation:
5.5. Dozowniki z dzieleniem strumienia (split)
Mała objętość gazu nośnego wpływa do kolumny (1-4 ml/min), podczas gdy dużo większa objętość (10-100 ml/min) uchodzi na zewnątrz poprzez bocznik. Po odparowaniu próbki pary mieszają się z gazem nośnym i są transportowane razem z gazem nośnym. Przyczynia się to do tego, że mała część odparowanej próbki jest wprowadzana do kolumny, a większa część próbki odprowadzana jest przez bocznik.

S/SL (Split/Splitless) injector; a sample is introduced into a heated small chamber via a syringe through a septum - the heat facilitates volatilization of the sample and sample matrix. The carrier gas then either sweeps the entirety (splitless mode) or a portion (split mode) of the sample into the column. In split mode, a part of the sample/carrier gas mixture in the injection chamber is exhausted through the split vent.
