一般說明
胶垫是加样针进样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。不适当的胶垫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。
它是经典Thermogreen LB-1隔垫的改良版。
- 可以在较宽的入口温度范围内(100°C至350°C)保持极低流失
- 经过预处理,开封即用
- 易于进针,并具有较高的穿刺耐受次数(适用于自动进样)
- Supelco独有的橡胶材料配方
應用
Thermogreen® LB-2隔垫适用于以下应用:
- 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 仪器采用耐热胶垫,避免载气泄漏、外来峰和邻苯二甲酸盐污染。
- GC 仪器采用耐热胶垫和粗针保护器,避免微量加样针造成不可逆损伤。
- 也可用于气相色谱仪进水进样口。
