2. The sampler should be immersed in the solution for several times before use to discharge the air bubbles in the needle tip. Otherwise, the correctness of the analysis and the capacity of the sample should be cleaned immediately after use to prevent the needle tip from being clogged or stuck.
3. If stainless steel oxide is found in the injector, affecting normal use, a small amount of soap can be inserted into the sampler and pulled back and forth several times on the stainless steel core to remove it, and then cleaned.
