一般說明

隔垫是注射器系统的一个非常重要的组成部分。它们通常采用弹性自密封材料制成,如硅橡胶、氯丁橡胶或氟橡胶。它有助于方便地导入样品,避免系统漏液。不合适的隔垫会在毛细管入口的高温条件下发生分解,导致色谱图的基线破坏和假峰。
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GC-MS分析过程中,最大限度地减少样品瓶固相微萃取(SPME)纤维的分析物的提取或流失。
  • 在GC仪器中使用耐热隔垫,以避免载气泄漏、无关峰和邻苯二甲酸酯污染。
  • 在GC仪器中使用耐药隔垫和粗针头保护器,避免由微量注射器引起的不可逆损坏。
  • 也可用于气相色谱仪的流入液采样口。
