好多客戶認為自己的樣品是粉狀的就是用干法粒度儀測試，樣品液態的就用濕法粒度儀測試，其實這也是不太準確的，下面小編給您介紹一下粒度儀濕法、干法的選擇。
A lot of customers that their sample is used for dry powder's particle size analyzer, sample liquid with wet particle size analyzer, which is actually not too accurate, following small series to introduce you to the choice of wet dry particle size analyzer.
樣品測試前是液態的用濕法粒度儀是沒錯的，干法測試不了液態樣品這點是沒錯的。
The sample is liquid before the test, and the wet particle sizer is correct. It is true that the dry test does not test the liquid sample.
樣品是粉末狀的用什么儀器測試呢？這選擇就很糾結了。拿金剛砂老說您干法測試沒問題，您用濕法也能測試，而且效果比干法還要好。水泥用干法測試沒問題，用濕法測試您可能懷疑數據準確性，因為水泥在水里是水解反應的。我明確告訴您水泥完*可以用濕法測試，只不過分散介質不要用水必須用無水乙醇測試。還有一些藥品找不到合適的液態分散介質，這樣的就只能用干法測試了。您要測試的樣品是具體是濕法測試好還是干法測試好，**咨詢一下海鑫瑞的技術人員，我們會竭誠為您服務。
The sample is powder. What instrument is used? This choice is very tangled. Take emery as you say. You have no problem with dry test. You can test it with wet method, and the effect is better than dry process. Dry test of cement is fine. Wet test. You may doubt the accuracy of the data because the cement is hydrolyzed in water. I specifically told you that cement can be completely wet tested, except that the dispersing medium does not use water and must be tested with absolute ethanol. Some drugs can't find the right liquid dispersing medium, so they can only be tested in dry way. The sample you want to test is whether the wet test is good or the dry test is good. It is better to consult Nekt's technical staff and we will serve you with all our heart.
