The invention discloses a cleaning solution for an ion source and an ion lens of a liquid chromatograph-mass spectrometer. The formula of the cleaning solution comprises five parts: (1) the volume ratio of methanol (chromatographically pure) to ultrapure water is 1: 1; (2) glucuronic acid; (3) the volume ratio of the ultrapure 2-butoxyethanol to the ultrapure 2-aminoethanol to the water is 5: 5: 90; (4) methanol (chromatographically pure); and (5) ultrapure water. According to the cleaning solution, 2-butoxyethanol and 2-aminoethanol act with water to generate a large number of tiny bubbles, compounds and molecular fragments adsorbed on the surfaces of an ion source and an ion lens can be completely and thoroughly removed, and the signal-to-noise ratio is obviously reduced. After cleaning by the cleaning solution formula process, pollutants in the ion source and the ion lens are thoroughly removed. The test verifies that no damage is caused after 100 times of repeated cleaning, and the ...
