Gas chromatography-mass spectrometer

Gas chromatography-mass spectrometerShimadzu anti pollution type high sensitivityGas chromatography-mass spectrometerGCMS-QP2020 is a fast mass spectrometry product with excellent hardware performance and intelligent software among similar products. Equipped with an efficient vacuum system and integrated high brightness ion source and shield technology, it has reached the level of FG in both quantitative and qualitative aspects. It is widely used in various fields such as food safety, environmental protection, analysis and metabolite analysis, research and development of high-performance new materials and chemicals, discovery of biomarkers, and diagnostic markers in the medical field.

Anti pollution type high sensitivityGCMS-QP2020It has the following characteristics:

1. Integrating high sensitivity and low experimental cost

Relying on mass spectrometry technology, compatible with multiple carrier gas types (He, H)₂，N₂）Explore the limits of mass spectrometry technology analysis. No need to replace the ion source, easily switch ionization modes.

（1）High sensitivity

adoptIntegrated Inert High Sensitivity Ion Source with Shield TechnologyandThe "OD lens technology"cooperate, coordinate, collaborateNew low-noise CPU boardEffectively reducing matrix interference and electronic noise in complex samples, achieving higher sensitivity (S/N ≥ 2000:1) in industry GCMS, and becoming a powerful tool for trace substance analysis in complex samples. In addition, setting tuning parameters can also be applied to the analysis of high concentration samples. Thus, ideal high-precision analysis results can be easily obtained within a wide dynamic range from low to high.

（2）New ultra efficient large capacity vacuum system

GCMS-QP2020 is equipped with a brand newLarge capacity and ultra efficient vacuum system——By using a turbo molecular pump with an ion source (200L/sec) and a quadrupole mass analyzer (200L/sec) for exhaust, a dual inlet differential exhaust volume of up to 400L/sec can be achieved, while the compressed gas effect is increased by more than three times, effectively ensuring the mass spectrometry state under any carrier gas conditions. *Efficient vacuum system * supports the following applications:

1) Support the simultaneous installation of two chromatography columns of different polarities into a vacuum system to form a 'Twin Line MS Dual Column System'. Effectively reducing the time required to replace chromatography columns in different applications without sacrificing sensitivity, switching between two chromatography columns can be achieved directly through simple software operations.

2) The ultra-high efficiency and large capacity vacuum system ensures a high vacuum degree in the mass spectrometry system, effectively reducing ion source contamination and thus reducing ion emissions

Maintenance operations of the source.

3) Support rapid start-up of the instrument, allowing for actual sample analysis within 30 minutes of startup, improving the stability and accuracy of the instrument

The reliability of the data.

4) The flow rate of the large column can reach 15 mL/min, so it can be connected to a wide caliber capillary column with an inner diameter of 0.53mm to achieve a large volume

Analysis with high throughput and high expansion requirements such as injection.

（3）Ultra fast scanning performance(technologyASSP^TM)

Adopting a high-precision all metal quadrupole mass analyzer, coupled with a newly designed high-speed data acquisition and processing platform, it has the advantages of being among similar products currently availableFaster scanning speed (20000 u/sec)And when collecting data at high speed, useAdvanced Scanning Speed Protocol（ASSP^TM）TechnologyBy accelerating ion transport and effectively reducing high-quality end discrimination, the sensitivity and accuracy of mass spectra can be reduced at high-speed scans of less than 10000 u/sec. Compared with traditional methods, the sensitivity is increased by more than 5 times, especially in the application of Fast GCMS, Scan/SIM simultaneous determination FASST mode, GC × GC/MS, which can effectively improve the sensitivity of scan data and obtain classical mass spectra, making GCMS-QP2020 more excellent in rapid analysis. （：U6610979）

3. Easy maintenance and * design

4. Ecological Model Design

（1）Ecology ModeEco Mode

GCMS-QP2020 can switch to the "Ecology Mode" ecological mode during standby, saving instrument power consumption and carrier gas consumption, which helps reduce daily instrument consumption and environmental emissions. Calculated based on working for 6 hours and standby for 18 hours per day, it can save 36% of power consumption compared to traditional models.

Shimadzu's management philosophy is "for the health of humanity and the earth", therefore, we attach great importance to environmental protection. The instrument adopts the Ecology mode design, which enables the emission of CO from the GCMS production line₂The quantity is only 30% of the previous manufacturing process.
