1 It is important to check for needle burrs, needle curls, and simple cracks before using the syringe.
2 In order to eliminate the residue of the sample before the syringe, it is necessary to use the sample for 5 to 20 cleanings. However, samples of 2 to 3 times at the beginning of Zui must be disposed of.
3 In order to remove air bubbles from the syringe, the needle tip is immersed in the sample solution to repeat the extraction and autosampler vials ejection operation. (It is easy to remove the bubbles from the needle to the upper side.)
4 Extract more samples than the final amount required by Zui, autosampler vials and then align with the tick marks. Be careful not to tilt the syringe. First, wipe the tip with a paper that does not produce fine fibers, and then inject it.
5 After use, the syringe must be cleaned with pure water or acetone and stored after air drying.
This is the end of the introduction of Precautions for using autosampler neddle. I hope it can help you.
