一般描述
用于需要插头隔膜的 Shimadzu GC。
隔膜是注射器注射系统的重要组成部分。通常由弹性体、自密封材料（如硅橡胶、氯丁橡胶或氟橡胶）制成。它适用于方便地引入样品，而不会导致系统泄漏。不适当的隔膜在毛细管入口的高温条件下分解，导致基线中断和色谱图中的鬼峰。
应用
Thermogreen ® LB-2 Septa 适用于以下应用：
- 在通过 GC-MS 进行分析的过程中，尽可能减少从小瓶中固相微萃取 (SPME) 纤维上的分析物的萃取或损失。
- GC 仪器采用耐热隔膜，避免载气泄漏、外来峰和邻苯二甲酸盐污染。
- GC 仪器采用耐热隔膜和粗针保护器，避免微量注射器造成不可逆损伤。
- 也可用于气相色谱仪进水进样口。
