Centralized collection system:
(1) The waste liquid interface of multiple wave phase chromatographs in each row is 20mm in the main pipeline, and each has a standard GL45 safety cover concentrator, PFA /PDFE capillary interface with 1.6 mm-3 mm and 6.4 mm-12 mm pagoda interface, which is suitable for waste liquid pipelines of various calibers and is completely sealed without volatilization.
(2) The sink-type invisible installation behind the test bench shall be adopted, and the main collection pipeline shall be arranged according to the inclination of 3-5 ℃ to ensure that the liquid flows slowly to the waste liquid collection barrel, so as to avoid liquid accumulation and a large amount of static electricity in the pipeline.
(3) safety switching valve design, in order to solve the chromatograph does not stop working in the state of the waste liquid barrel replacement, we designed a safety switching valve. The design of safety switching valve + double barrel is adopted at the terminal of waste liquid collection.
(4) The pipeline components are made of ptfe modified plastic to ensure chemical stability, and will not deform in the collection process, resulting in the accumulation of waves in the pipeline. The pipeline is reinforced by threaded connection, which is convenient for maintenance and addition of components. It has good chemical characteristics and physical flexibility and avoids liquid phenomenon.
(5) ptfe material guide hose is used for terminal docking, which effectively slows down the flow rate of waste liquid and reduces electrostatic risk, with a length of 600mm + 5%.
(6) A stop switch is installed at the end of the main pipeline and the sealing cover of the waste liquid barrel, which effectively prevents the leakage of waste liquid and is convenient to operate.
(7) Equipped with multi-channel sound and light alarm to monitor liquid level, 12V power supply, low voltage and reliable.
(8) The sealing cover of the waste wave barrel is equipped with an adsorption filter with a validity period of half a year, which is quick to disassemble and assemble. It is equipped with a visual time button, which can balance the pressure state in the container and ensure the normal operation of waste liquid collection in a sealed state. The adsorption effect reaches more than 99% within the validity period.
(9) equipped with 20L PEHD material barrel, a full set of acid and alkali resistant, corrosion resistant plastic products.
