[求助] 关于GC-MS检测器的问题已有1人参与

To separate and identify all organic compounds present in soluUV-DADtion during catalytic testing, gas chromatography coupled with mass spectrometric (GC–MS) analysis was carried out with a Quattro micro GC Mass Spectrometer (RAB 241, Waters, USA) using a DB-5 column (30m×250mm×0.25mm).Ultra pure helium was used as the carrier gas at a flow rate of 1.0 ml/min-1. The aqueous reaction mixture was extracted with chloroform before GC–MS analysis. The temperature program was as follows; initial column temperature was held for 2 min at 70℃, ramped at 10℃/min to 280℃, with final hold for two minutes at 280℃. The sample was injected in the splitless mode. Product detection was by UV-DAD at 269 nm.
文章里面看到的，在GC里面用到了 UV-DAD检测器。使用GC会用到这种检测器吗，还是因为是GC-MS的原因？有点迷茫了。。。。
