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。Alotofcustomersthattheirsampleisusedfordrypowder'sparticlesizeyzer,sampleliquidwithwetparticlesizeyzer,whichisactuallynottooaccurate,followingsmallseriestointroduceyoutothechoiceofwetdryparticlesizeyzer.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。Thesampleisliquidbeforethetest,andthewetparticlesizeriscorrect.Itistruethatthedrytestdoesnottesttheliquidsample.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，好咨询一下海鑫瑞的技术人员，我们会竭诚为您服务。Thesampleispowder.Whatinstrumentisused?Thischoiceisverytangled.Takeemeryasyousay.Youhavenoproblemwithdrytest.Youcantestitwithwetmethod,andtheeffectisbetterthandryprocess.Drytestofcementisfine.Wettest.Youmaydoubttheaccuracyofthedatabecausethecementishydrolyzedinwater.Ispecificallytoldyouthatcementcanbecompletelywettested,exceptthatthedispersingmediumdoesnotusewaterandmustbetestedwithabsoluteethanol.Somedrugscan'tfindtherightliquiddispersingmedium,sotheycanonlybetestedindryway.Thesampleyouwanttotestiswhetherthewettestisgoodorthedrytestisgood.ItisbettertoconsultNekt'stechnicalstaffandwewillserveyouwithallourheart.
