Nu Horizon IRMS仪器专为灵活性，可靠性和高性能而设计，具有用户友好的仪器控制和数据分析软件。该下一代仪器具有双入口（DI）和连续流量（CF）分析的独特功能，可与各种样品制备外围设备连接。收集器阵列使用获得zl的可变色散变焦光学器件来精确地重合监测2到100的质量。
样品制备
Nu Horizon配置了广泛的CF和DI样品引入系统。 CF进口通过自动隔离阀连接，包括毛细管气相色谱（Agilent 7890A）和元素分析仪（Eurovector或HEKAtech）。双入口位于独立的机柜中，离子源外壳上带有进样阀，可zei大限度地减少死体积和气路长度。 DI样品选项包括碳酸盐/磷酸制备单元，水平衡单元和具有任选裂化器的样品歧管。

The Nu Horizon IRMS instrument is designed for flexibility, reliability and high performance, with user friendly instrument control and data analysis software. This next generation instrument possesses unique features for both Dual Inlet (DI) and Continuous Flow (CF) analysis, interfacing with a wide range of sample preparation peripherals. The collector array uses the patented variable dispersion zoom optics to monitor masses from 2 to 100 with exact coincidence.
Sample preparation
The Nu Horizon is configured for a wide range of both CF and DI sample introduction systems. CF inlets are connected via an automated isolation valve and include capillary gas chromatography (Agilent 7890A) and elemental analysers (Eurovector or HEKAtech). The Dual Inlet is located in a separate cabinet with the sample inlet valve on the ion source housing, minimising dead volume and gas path lengths. DI sample options include a carbonate/phosphoric acid preparation unit, a water equilibration unit and a sample manifold with optional crackers.
