Highlights
Hardware

• Electronic pressure/flow control system (EPC/EFC) for self-developed GC 6800 system
• Patented El filament set provides highly efficient electron emission, a maximum of 350u A
• Quality mass analyzer with pre-filter reduces quadrupole pollution
• High-energy dynode electron multiplier ensures good sensitivity
• Vacuum system with quality mechanical and turbo molecular pumps guarantees stability and reliability
• Full scale gauges monitor vacuum states in real time
• Self protection system guarantees safety of operators and core parts under abnormal conditions
• RF power supply digital compensation technology ensures better sensitivity and resolution in full mass range

Software

• The software "ChemAnalyst" controls auto sampler (AS), gas chromatograph (GC) and mass spectrometer (MS); data are acquired and transferred by high-speed network card
• Full Scan and selective Ion Monitoring (SIM) modes are available
• The system supports manual and automatic tuning, display of total ion current (TIC) and mass chromatogram (MC)
• The data processing section searches target compounds in NIST 2011 based on mass spectra of samples, displays search results which include retention times, structural formula and standard mass spectra, and compares the abundances of standard and real target ions.
• Users can make accurate qualitative and quantitative analyses
