Main advantages: It can simultaneously degas up to 4 pipelines, optimize GPC solvents, improve baseline stability and reduce noise, enhance pump performance, reduce water bubbles and air pockets, improve laboratory safety, prevent volatile solvents from entering the air, prevent the generation of water bubbles in the detector and solvent mixing system, and not cause the consumption of mixed solvents. It only uses the main power supply, does not require a high-pressure air cylinder, and has a simple design. It only occupies an area of 80mm × 250mm. The reason why you need a GPC degasifier is that degasifying solvents is very important for GPC, and the generation of water bubbles should be reduced when solvents are mixed. For GPC, more volatile organic solvents are used and RI or other sensitive detectors are used for detection. Degassing can increase sensitivity and reduce baseline noise, especially at low ultraviolet wavelengths. When degassing 100% organic solvents, it is recommended to use S-shaped brackets or reinforced versions to secure accessories and reduce the possibility of leakage. Simultaneous solvent degassing and online degassing have been proven to be more effective in removing dissolved gases from the mobile phase than sonic degradation or helium injection methods. An instrument can perform up to 5 channels of degassing simultaneously. Each Teflon? The capacity of AF channels is very small (480 µ l), which can quickly achieve balance and has a very short start-up time. Teflon? Is the permeability of AF membrane better than Teflon? Is PTFE 50 times better than the new Teflon? Has the performance of AF membranes in many other degassing systems already surpassed that of old Teflon? PTFE diaphragm. This allows for the use of shorter pipelines when removing dissolved gases. Very short balancing/rebalancing time is very easy to fill with short vacuum pull-down time, usually 3 minutes for Teflon? AF can eliminate air pockets and water bubbles generated from cleaning solution containers in advance. Continuous vacuum pump technology for HPLC solvent degassing using ZHCR? The Zero Hysteresis Constant Run stepper motor is specifically designed and developed to control the vacuum pump for membrane degassing of HPLC mobile phase. This allows the pump to maintain a vacuum state (50 mmHg) by varying the speed of the stepper motor. The pump will be in a high-speed state during initialization, which provides a quick pull-down and approaches the vacuum control point at the same time, until the desired vacuum level is reached, and the speed will gradually decrease. This patented control method can maintain an almost permanent vacuum state in the solvent deaerator, and is not affected by changes in deaeration compliance. Therefore, the baseline fluctuations caused by vacuum hysteresis will be eliminated, so as not to repeatedly start and stop the pump like in old or current systems.
