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);
Skyray Instrument is the only legal distributor authorized by NIST/EPA/NIH in China mainland, which guarantees the latest version and free online upgrade of NIST (current version NIST ***1).
The data processing section searches target compounds in NIST ***1 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;
