干法湿法激光粒度仪、激光粒度分析仪的选择

好多客户认为自己的样品是粉状的就是用干法粒度仪测试,样品液态的就用湿法粒度仪测试,其实这也是不太准确的,下面小编给您介绍一下粒度仪湿法、干法的选择。
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.
样品测试前是液态的用湿法粒度仪是没错的,干法测试不了液态样品这点是没错的。
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.
样品是粉末状的用什么仪器测试呢?这选择就很纠结了。拿金刚砂老说您干法测试没问题,您用湿法也能测试,而且效果比干法还要好。水泥用干法测试没问题,用湿法测试您可能怀疑数据准确性,因为水泥在水里是水解反应的。我明确告诉您水泥完全可以用湿法测试,只不过分散介质不要用水必须用无水乙醇测试。还有一些药品找不到合适的液态分散介质,这样的就只能用干法测试了。您要测试的样品是具体是湿法测试好还是干法测试好,最好咨询一下海鑫瑞的技术人员,我们会竭诚为您服务。
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.
