为了研究小行星对土卫六以及其他卫星和行星撞击产生碳质产物的情况，利用二级轻气枪进行了模拟实验。将约 6.5 km/s 的小型聚碳酸酯或金属子弹注入充满 1 atm 氮气的加压靶室内，与冰 + 铁靶或铁靶或冰 + 己烷 + 铁靶碰撞。撞击后，含有细颗粒的黑色烟灰沉积在室壁上。仔细收集烟灰，并通过高效液相色谱 (HPLC)、傅里叶变换红外光谱 (FT-IR) 和激光解吸飞行时间质谱 (LD-ToF-MS) 进行分析。 HPLC 分析的结果是，当使用冰 + 己烷 + 铁靶时，在样品中发现了约 0.04–8 pmol 的甘氨酸和少量的丙氨酸。在冰+铁目标和铁目标的情况下，产生较少的氨基酸。 FTIR 和 LD-ToF-MS 分析也支持了氨基酸的鉴定。
In order to investigate impact production of carbonaceous products by asteroids on Titan and other satellites and planets, simulation experiments were carried out using a 2-stage light gas gun. A small polycarbonate or metal bullet with about 6.5 km/s was injected into a pressurized target chamber filled with 1 atm of nitrogen gas, to collide with a ice + iron target or an iron target or a ice + hexane + iron target. After the impact, black soot including fine particles was deposited on the chamber wall. The soot was carefully collected and analyzed by High Performance Liquid Chromatography (HPLC), Fourier Transform Infrared Spectroscopy (FT-IR), and Laser Desorption Time-of-Flight Mass Spectrometry (LD-ToF-MS). As a result of the HPLC analysis, about 0.04–8 pmol of glycine, and a lesser amount of alanine were found in the samples when the ice + hexane + iron target was used. In case of the ice + iron target and the iron target, less amino acids were produced. The identification of the amino acids was also supported by FTIR and LD-ToF-MS analysis.
