Product Details
- 保留时间锁定 (RTL) 功能保持不同进样、不同色谱柱、不同仪器和不同实验室之间的保留时间不变
- 微板流路控制技术 (CFT) 提供独特的仪器功能，例如多维气相色谱（GC-GC/Deans Switch 中心切割）、配备流路调制器的全二维气相色谱 (GC x GC)，以及分析柱柱前、柱中和柱后反吹
- 单丝 TCD 无需单独的参比气，也无需手动调节电位计，能够提供漂移极小的稳定基线
- 自动调节检测范围的 FID 能够在单次进样中实现十亿分之一 (ppb) 到千分之一级的检测和定量分析
- 集成 SCD/NCD（硫或氮化学发光检测器）能够在复杂基质中对硫或氮污染物进行低至 ppb 级的检测、等摩尔响应和定量分析
- 氦气节省模块和替代载气解决方案显著降低氦气的使用量，提高实验室分析的灵活性并节省成本
- 可选的氢气传感器模块系列 2 使用内置智能诊断功能持续监控运行状态，可及早检测到氢气泄漏并关闭气流，仅需每六个月校准一次即可
- 大阀箱 (LVO) 实现多种分析方法的组合并简化维护流程
- 多模式进样口 (MMI) 作为程序升温气化进样器具备灵活的功能
- 安捷伦惰性流路大大提升了活性化合物从进样到检测的灵敏度
- 低热容 (LTM) 模块（最多可同时安装和操作 4 个模块）通过快速色谱柱加热和冷却技术提高了样品通量
多维气相色谱
多维色谱在流路中引入具有不同固定相的第二根色谱柱。复杂样品通常具有共洗脱化合物，因此通过中心切割或 GCxGC 增加额外色谱柱的选择性，从而提高气相色谱分离能力，并为峰重叠问题提供解决方案。
