熱裂解氣相層析質譜儀 Gas Chromatograph/ Mass Spectrometer

製造商：SHIMADZU
型號：GCMS-QP2010
單價：$600,000
數量：一式
地點：桃園平鎮
製造日期：2006
規格：
氣相層析儀為利用氣體作為移動相之層析方法，氣體僅扮演攜帶功能(carrier gas)並不具分離效果，一 般常用氣體為：N2, He, H2。氣相層析主要分離之功能由管柱材質(固定相)及管柱溫度所決定，依管柱性質可區分為：氣液相層析(Gas-Liquid Chromatography, GLC)及氣固相層析(Gas-Solid Chromatography, GSC)，其中氣液相層析為最常用之分析方法。
氣相層析質譜儀係經由氣相層析之高分離效果與質譜之高辨別性结合之機器，將氣相層析分離之成分蒸氣進入質譜儀分析獲得分子結構之資訊，特別適用於具揮發性且對熱安定性化合物或混合物之分離 及質譜檢測。

Introduction:
The GCMS-QP2010 Series instrument is a bench-top type gas chromatograph/mass spectrometer intended for high-precision GC/MS analysis. The instrument enables mass spectrum measurement for qualitative analysis or identification of unknowns and Selected Ion Monitoring (SIM) measurement for quantitation of trace constituents.
The standard model includes the following components:
  • GC-2010 high-performance gas chromatograph
  • Vacuum differential pumping* by the turbo molecular pump with the rotary backing pump
  • Vacuum gauge for chamber pressure monitoring*
  • Direct-coupled GC/MS interface
  • Electron Impact (EI) ion source with independent temperature control
  • Electron energy/current variable dual filament ion source
  • Quadrupole mass filter with pre-rods
  • Electron multiplier detector with conversion dynode
  • Power source and instrument control circuit
    • *For Single TMP models, the vacuum differential pumping becomes a single pumping, and the ion gauge is not included. GCMSsolution Ver. 2 software is used to control the GSMS-QP2010 and perform data acquisition and post run analysis. The software includes the following functions:
  • Control of GSMS-QP2010 and peripherals such as the autosampler, and automatic adjustment of the instrument by autotuning
  • QA/QC functions support data precision and quality management.
  • Creation of analysis methods
  • Scan and SIM data acquisition
  • Qualitative processing which includes the display and processing of mass spectrum as well as library searches
  • Quantitative processing which includes the creation of compound tables, calibration curves and concentration calculations
  • Customizable reports
  • Sequential data acquisition/analysis by batch processing
