Features
- 保留時間鎖定 (RTL) 功能保持不同進樣、不同色譜柱、不同儀器和不同實驗室之間的保留時間不變
- 微板流路控制技術 (CFT) 提供獨特的儀器功能，例如多維氣相色譜（GC-GC/Deans Switch 中心切割）、配備流路調制器的全二維氣相色譜 (GC x GC)，以及分析柱柱前、柱中和柱后反吹
- 單絲 TCD 無需單獨的參比氣，也無需手動調節電位計，能夠提供漂移極小的穩定基線
- 自動調節檢測范圍的 FID 能夠在單次進樣中實現十億分之一 (ppb) 到千分之一級的檢測和定量分析
- 集成 SCD/NCD（硫或氮化學發光檢測器）能夠在復雜基質中對硫或氮污染物進行低至 ppb 級的檢測、等摩爾響應和定量分析
- 氦氣節省模塊和替代載氣解決方案顯著降低氦氣的使用量，提高實驗室分析的靈活性并節省成本
- 可選的氫氣傳感器模塊系列 2 使用內置智能診斷功能持續監控運行狀態，可及早檢測到氫氣泄漏并關閉氣流，僅需每六個月校準一次即可
- 大閥箱 (LVO) 實現多種分析方法的組合并簡化維護流程
- 多模式進樣口 (MMI) 作為程序升溫氣化進樣器具備靈活的功能
- 安捷倫惰性流路大大提升了活性化合物從進樣到檢測的靈敏度
- 低熱容 (LTM) 模塊（最多可同時安裝和操作 4 個模塊）通過快速色譜柱加熱和冷卻技術提高了樣品通量

多維氣相色譜
Multidimensional chromatography increases the resolving power of the GC by adding a different stationary phase through heart-cutting or GC x GC. Complex samples often have coeluting compounds - adding the selectivity of a second column provides a solution to the problem of overlapping peaks. Learn More多維氣相色譜
