发帖数: 831 | 1 最近做SPME-GC实验搞断了几根fiber，很郁闷。
发现问题是GC inlet的septum很难用SPME syringe穿过，好不容易穿过后，septum的碎
屑沾在syringe头上，当脆弱的fiber出来的就断了。但是如果事先将septum的洞戳大的
话，又很可能会漏气。我在考虑是不是我的septum不适合SPME。我现在用Thermo
Scientific的Septa coated BTO 17 mm. 请问各位做SPME-GC的达人一般都用什么fiber
? 或是给我的问题提点建议？请各位大牛多多指教，谢谢先！ |

right liner and septumS. Check Spelco website and make sure you use the
right parts. |
