Description

Technical Field

[0001] The utility model relates to the technical field of chromatographs, in particular to a pulse ultrasonic aerosol ion chromatograph. Background Art

[0002] The pulsed ultrasonic aerosol ion chromatograph is an advanced instrument that combines the advantages of pulsed ultrasonic technology and ion chromatography technology, and is used to efficiently and accurately analyze the ion components in aerosol samples. The main technical points of the pulsed ultrasonic aerosol ion chromatograph are: the mesh size of the frosted inner tube of the gas sampling annular wet tube is arranged in a matrix to effectively improve the gas absorption rate and reduce the generation of bubbles. For the absorption of aerosols, rapid cyclotron condensation absorption is adopted to avoid the formation of bubbles to the greatest extent. Through pulsed ultrasonic technology, the tiny bubbles in the aerosol and gas absorption liquid are ultrasonically removed to reduce the damage to the chromatographic column, suppressor, etc., to ensure that the spectrum peak is not disturbed, and to improve the quality of effective data.

[0003] In the process of using the energy of ultrasonic waves to affect the movement of ions in a sample, the generation and propagation of ultrasonic waves may cause the instrument to vibrate on the workbench, which will affect the performance of the instrument and the analysis results. Therefore, those skilled in the art provide a pulsed ultrasonic aerosol ion chromatograph to solve the problems raised in the above background technology. Utility Model Content

[0004] 1. Technical issues to be resolved

[0008] Preferably, the left and right side walls of the limiting frame are slidably engaged with the limiting plate.

[0009] Preferably, a threaded sleeve is installed on the top of the limiting frame, the threaded sleeve is threadably sleeved with a bolt, and the bolt is in pressing contact with the top of the chromatograph housing.

When the suction cup is connected to the table top, the bolt is rotated downward, and the end with the rubber sleeve is squeezed and contacted with the top of the chromatograph housing. As the bolt continues to move downward and press, the negative pressure between the suction cup and the workbench increases, and the friction between the foot pad and the workbench increases. Therefore, when the pulse sound wave element inside the chromatograph housing is working, the friction of the foot pad and the negative pressure of the suction cup are increased, thereby greatly improving the stability of the chromatograph housing on the workbench.

As the bolt 8 continues to move downward and press, the negative pressure between the suction cup 6 and the workbench increases, and the connection becomes tighter. At this time, under the pressure of the bolt 8, the friction between the foot pad 3 at the bottom of the chromatograph housing 1 and the workbench surface increases. Therefore, when the pulse sound wave element inside the chromatograph housing 1 is working, the friction of the foot pad 3 and the negative pressure of the suction cup 6 are increased, which greatly improves the stability of the chromatograph housing 1 on the workbench.

[0024] The front side of the chromatograph housing 1 in the utility model is provided with an injection port 2, and a limit plate 4 is vertically installed on the two side walls of the chromatograph housing 1, and a limit frame 5 is sleeved on the peripheral side of the chromatograph housing 1. The two sides of the limit frame 5 are slidably engaged with the limit plates 4 on the two side walls of the chromatograph housing 1, so that the limit frame 5 is slidably engaged with the housing of the chromatograph housing 1, and a suction cup 6 is installed at the bottom of the limit frame 5, and the suction cup 6 is used to be sucked and fixed to the table top of the workbench;
