Name of Instrument: Gas chromatography Cascade MS/ MS

Type and Specification: Agilent 7890B-7000C

Manufacturer: Agilent

Purchase Time: 2014

Main Uses: It is to implement the high sensitivity qualitative and quantitative analysis of the organic molecular compound including the gasifiable pesticide, antibiotics, food additive and prohibited drug etc. in food and agricultural products.

Main Technical Indexes:

1. The operating temperature is 4˚C~ 400˚C,0.1˚C program setting;

2. Maximum operating time: 999.99 minutes;

3. Heating rate: 0.1~ 100 ˚C/min;

4. The electron parameter can be programmed to set the pressure, velocity and diversion ratio, and the electron flow controls the sweeping, and the great pressure can be up to 150 psi with the maximum service temperature 400˚C, pressure setting precision 0.001 psi and maximum diversion ratio 7300:1;

5. It can change the chromatographic column without unloading the vacuum;

6. It has the retention time locking function and the retention time locking chromatography library;

7. Range of liquid injection volume: 0.1- 50 μL, injection volume linearity≥99%, area reproducibility<0.3% RSD;

8. The mass analyzer is the hyperboloid triple- quadrupole tandem which can independently control temperature and promote the ion transmission efficiency and the ionic focusing and  anti- pollution ability;

9. Instrument detection limit index and precision: 4fg octafluoronaphthalene;

10. Sensitivity: 100fg octafluoronaphthalene, signal- to- noise ratio≥5000:1;

11. Scan rate of MRM: 800 MRM/s;

12. Resident time of minimum ion: superior to 1 ms ;

13. The temperature of ion source is independently controlled, and the highest temperature can be above 300˚C;

14. Detector: electron multiplier;

15. The system is the two- stage molecular- turbo pump high vacuum system, and the source region and analysis region form a difference pumping system.
