Attention problem


1. Prepare samples to maximize their surface area, which should not contain acid-base substances and volatile organic solvents;


2. The sample must be completely frozen into ice, and if there is residual liquid, it will cause vaporization spray;


3. Note that the cold trap is about minus 65 degrees and can be used in low temperature refrigerators, but must be insulated to prevent frostbite;


4. Before starting the vacuum pump, check whether the water valve is tightened, whether the inflation valve is closed, whether the contact surface of the plexiglass cover and the rubber ring is clean and free of dirt, and is well sealed;


5. During the freezing process, the temperature gradually decreases. The sample can be taken out for a while (still in a frozen state) and dried to shorten the drying time.
