小中大【求助】岛津气相色谱，如何设置不完全分流模式？

前辈们好！SPME进样，气相测定MTBE的文献中，有这样一种进样模式。我查了很多资料，猜想大概应该是不完全分流模式吧？文献中讲述的，我不太懂。希望做过的前辈，给我指导一下！多谢了！文献如下：
The injection port of the gas chromatographic instrument had a splitless flow into the column for 1 min to ensure that the desorbed species were trapped at the beginning of the column. After that, the gas flow rate became split with a 25:1 flow ratio for the remaining run time. The reactant and products were separated with a 30 m by 0.25 mm Phenomenex ZB-624 column, designed to separate volatile organic compounds.TwoGCoven temperature control methods were used to analyze the compounds. The first method used an initial oven temperature of 0 °C, which was held at this temperature for 5 min, and then ramped at a rate of 10 °C/ min to 100 °C. The oven temperature was then ramped at 50 °C/min to a final temperature of 225 °C.
