    全二维气象色谱质谱联用 SAI

    技术参数

    1.英国SAI公司的GCxGC TOF质谱。

    2.对用户已有的所有型号的Agilent 6890气相色谱升级为GC TOF或者GCxGC TOF(包括计算机及软件)。

    GC-ToF-MS

    SAI now offer a comprehensive GC system using the Zoex loop modulator and specialised software in combination with a GCToF MS system.

    GC x GC is a rapidly growing technique for the analysis of complex samples. Because GC x GC is both a qualitative and quantitative technique, most GC applications can be accomplished using GC x GC. It enables the analyst to separate and identify trace levels of compounds in a variety of matrixes. When combined with a ToF systems offering high scan rates and sensitivity, the full potential of GC x GC can be fully realised.



    Some GC x GC applications are:

    Petroleum Liquids Environmental Forensics PCBs/Dioxins/Pesticides Flavours & Fragrances Air Toxics Industrial Process Diagnosis Pyrolysates (Fire Debris, Tobacco) Catalysis Soils and Sediments Chemical Warfare Agents



    Gas Chromatograph

    The kit comprises of the Zoex loop modulator that can be fitted to most GCs, and 1st and 2nd dimension columns. Fully integrated hardware and control of the whole system by software.



    Real time display of 2D chromatogram as it is being acquired. Optional GC image program that features automatic peak detection and quantification capability. GC Image is a software system for visualising, processing, analysing, and reporting on images produced in two-dimensional gas chromatography(GCXGC). GC Image software, featuring automatic peak detection and quantification capability, has two main interfaces:

    • GC Image

    • GC Project



    GC Project provides support for organising or managing and reporting on the sets of data developed during GCXGC analyses.

    Examples of GCxGC ToFMS data.

    仪器介绍  

    近年来,GCxGC TOF应用越来越广泛。其有用性已经逐渐被人们所认识,可能的应用领域会比已开展的广泛的多。一般来说,当样品中物质的个数多于 100 时,使用 GCxGC TOF会比一维 GC 好得多。当柱系统选择得当时,此种技术更适于需族分离的复杂样品分析。即使样品中物质个数在 30~100 间, GCxGC TOF也会具显著优越性。 由于GCxGC TOF的高度峰容量和分辨率,这个技术将会在复杂体系的分离分析中占据越来越重要的地位。这些典型的复杂样品包括:阻燃剂如多氯联苯( PCBs )、多溴二苯醚和联苯( PBDEs 和 PBBs ),氯代烷 (PCAs) ,多氯萘 (PCNs) ,香气如多环麝香化合物,氯代二恶英和呋喃,农药和除草剂如毒杀芬和多氯三苯 (PCTs) ,石化产品、精油及食用油等。复杂体系中的手性物质的分离, GCxGC TOF技术也会发挥很大作用。对咱们中国来说,传统中草药中挥发性化合物的分析和传统名白酒中香味成分的分析也是此种技术发挥作用的地方。
       广泛应用于:石油化工、环境科学、农药、中药等等。
