[5. Product Performance]

5.1 Working conditions

The ⑴ is used in the laboratory;

⑵ temperature: 15~27℃ (optimal: 18~21℃).

⑶ humidity: maximum relative humidity of 20%~80% (no condensation).

⑷ power supply requirements: voltage 220 V, frequency 50 Hz, 16 A

The ⑸ room should be clean and dust-free, with good exhaust air. Mass spectrometer should be placed smoothly on the workbench, without strong mechanical vibration around it

Dynamic and electromagnetic interference sources.

⑹ is well grounded with zero ground voltage <2 V.

⑺ This product is a vertical mass spectrometer movable all-in-one machine, in the fixed use in the laboratory environment

Do not move during the turn, can move after shutdown.

⑻ This instrument can reach a steady state through all necessary hardware diagnosis and tuning correction.2

The ⑼ normal operating atmospheric pressure range is 86kPa~106kPa.

5.4 The mass spectrometer ranges from 20 to 2000 D a.

5.5 Quality Accuracy

The mass of the ion measured by the mass spectrometer is in the range of ± 0.2 Da.

5.6 Mass stability

Within 24 hours, the mass spectrometer measured the resulting ion mass stability in the ± 0.05 Da range.3

5.7 Mass resolution

Half peak width can be set at 0.4,0.7, mass resolution not less than 1500.

5.8 Scan speed

The maximum scanning speed of the mass spectrometer was 10,000 D a / sec.

5.9 SIR scan speed

SRM scans with a speed ranging from 1 pair / s to 500 pairs / s.

5.10 SIR executable number

The ⑵ heating temperatures can be set from 0℃ to 650℃.

5.13, Detection function

5.13.1 Detection limit

The detection limit of the analysis was determined by using a certain amount of processed samples to be tested.

(1) The minimum detection limit of the sulfonamide solution in the ESI positive ion mode is 1pg.

(2) The minimum detection limit of chloramphenicol is 10 pg in the ESI negative-ion mode.

5.13.2 Linear

In view of the specific standard substances, a series of standard solutions are used to determine the linear range of the method.

(1) In the concentration range of 0.4 to 90.0 ng/mL, the linear correlation coefficient r should be> 0.990.

⑵ is within the concentration range l. 0 to 50.0 of chloramphenicol water in µ g/mL, and the linear correlation coefficient r should be> 0.990.

5.13.3 Repeatability

Determine succinylacetone and nonderivatized multiple amino acids, carnitine determination kit (tandem mass spectrometry), and tacromer

The reproducibility of different concentrations of substances to be tested, such as Si solution, glucool solution 1,5-dehydrated, and potassium bromate solution, with relative standard deviation

Poor RSD of 10.0%.4

5.13.4 Accuracy

Can meet one of the following indicators:

A concentration of 1.0 ng/mL ± 0.5 ng/mL was the absolute deviation of the measured value from the theoretical value

Should not be greater than 5.0%.
