Instrument Performance：Extractor Ion Source - The ‘push-pull’ principle of the Extractor Ion Source delivers more ions to the mass analyzer and increases confidence of your trace analysis methods.

Instrument Detection Limit (IDL)：Replace signal-to-noise ratio (S/N) with the new industry standard that measures the true sensitivity of your mass spec instrument.

Equipped with CI ion source：Increase the types of the target analyte，Heated Gold Quadrupole.

Triple off-axis detector(TAD)：Optimizes signal-to-noise by combining efficient ion collection and amplification with the elimination of neutral noise.GCMSD MassHunter with MSD ChemStation Data Analysis - Supports the MassHunter data analysis workflow for all instruments and the classic MSD ChemStation workflows for your GC/MSD and GC only operation.

General Measuring Principle：Gas chromatograph consists of carrier gas source、inlet system、chromatographic column、Oven、detector and a data processing system. Its working principle is based on gas as mobile phase, Samples are vaporized into the gasification chamber, And with the carrier gas into chromatographic column, and then be separated (Different components in the stationary phase has different adsorption reaction),Isolated components entered into the mass spectrometer. Mass spectrometer is mainly composed of sample parts, ion source, quality filter (analyzer), ion detector and other major parts. Its basic principle: the electron bomb ardent or other way to make the material being measured ionization, the formation of various sorts of mass-to-charge ratio (m/e) of ions, and then by using the theory of electro-magnetism and the ions according to different the mass-to-charge ratio of different types of ion separation and measurement, to determine the molecular weight and structure of the materials to be tested.

Test components：air、soil、water、plants、persistent organic pollutants (pops) in sediments, such as polycyclic aromatic hydrocarbons (PAHs) and Oxygen、Nitrogen derivatives (OPAHs, NPAHs), Hopane, Polychlorinated biphenyls (PCBs), etc.

Sample Pretreatment：Samples need to be extracted by the solvent and then can be measured.

Test parameters：SIM IDL<10 fg (n=8, Sample 100 fg octafluoronaphthalene/C10H8).
