Precautions for measurement

1. When injecting the sample into the electrolytic cell, the tip of the injector must be inserted with the reagent. The sample should not be in contact with the inner wall of the cell bottle and the electrode.

2, the typical measurement range of the instrument is 10 micrograms ~ 10 milligrams, in order to get accurate results, the injection volume should be controlled according to the water content of the sample, (ie; the water content is large to reduce the injection volume; the water content is small Increase the injection volume) Generally, the 100 microliter sampler delivered by the manufacturer can be used. The display value of the control instrument is optimal in the range of 100-1000 micrograms of water. When the moisture content is 0.01%, the sample can be used as a 1 ml sampler. Re-injection saves reagents and saves time.
