Key points of operation and evacuation in solid phase extraction device test

Shanghai Haozhuang Instrument Co., Ltd. developed the LNB brand solid-phase extraction device, which is energy-saving and environmentally friendly, leading the country. Professional manufacturing is more guaranteed and affordable. Key points of operation of vacuum solid phase extraction device 1. Configure a liquid collection device between the vacuum source and the device room. Connect the vacuum source, liquid collection device and solid phase extraction device in sequence with a sturdy vacuum tube. 2. When using vacuum, do not allow the vacuum to exceed 25 ”Hg. 3. Adjust the vacuum by: A. Purge valve-can control the flow rate of the device system. (When the purge valve is connected to the vacuum gauge connection hole and the vacuum When the holes in the rod are aligned, the vacuum in the device will be released.) B. Sealing plug-Adjustable flow rate of CLEAN SCREEN®, CLEAN-UP®, XtrackT® and other SPE columns. 4. Remove under vacuum. Before the SPE column, make sure that the sealing plug is closed. If the device system is not completely deflated, it will cause the splash or overflow of the eluent and be damaged. 5. Disassemble the vacuum gauge and valve regularly to clean and lubricate each part .

Vacuum gauge and valve Pass the threaded vacuum connecting rod (A) through the small hole on the side of the glass tank. The small hole on the club head is facing down, and the hole on the outer part of the rod is facing upward. Put the black O-ring (B) on the rod, and then put the Teflon washer (C) with the uneven side facing the O-ring. Screw the valve body (D) onto the stem, tighten and align the holes on the valve body and stem with the holes. The O-ring should maintain tightness with the glass groove. (Note: Do not use vise and any tools that may damage the thread, the sealing surface of the bleed valve or the groove on the stem.) Put the bleed valve (E) onto the valve body and screw on the fixing nut (F). Tightening the nut makes the air release valve tight, but it cannot be screwed tightly. The valve can rotate freely, and the other parts of the valve assembly must remain fixed. (Note: If necessary, you can wrap some Teflon tape on the stem thread near the valve body to maintain a proper tightness with the fixing nut.)
