分類1.按兩相所處物理狀態(tài)分類氣相層析：氣液層析（固定相為液體）和氣固層析（固定相為固體），流動相為氣體。液相層析：液液層析（固定相為液體）和液固層析（固定相為固體），流動相為液體。按層析方式分類柱層析：固定相裝于柱內(nèi)，使樣品沿著一個方向移動而分離。薄層層析：將適當(dāng)粘度的固定相均勻鋪在薄板上，點樣后，用流動相展開。紙層析：用濾紙作液體的載體，點樣后用流動相展開。根據(jù)層析原理分類：常用分類法吸附層析：固定相是固體吸附劑，通過對不同溶質(zhì)吸附力強(qiáng)弱不同進(jìn)行分離。

另外，有的機(jī)種給定分辨率與輸出分辨率不相同。、裝設(shè)變頻器時安裝方向是否有限制。變頻器內(nèi)部和背面的結(jié)構(gòu)考慮了冷卻效果的，上下的關(guān)系對通風(fēng)也是重要的，對于單元型在盤內(nèi)、掛在墻上的都取縱向位，盡可能垂直安裝。、不采用軟起動，將電機(jī)直接投入到某固定頻率的變頻器時是否可以？在很低的頻率下是可以的，但如果給定頻率高則同工頻電源直接起動的條件相近。將流過大的起動電流（6~7倍額定電流），由于變頻器切斷過電流，電機(jī)不能起動。

廂式壓濾機(jī)性能穩(wěn)定，艱苦耐磨，一般要比板框壓濾機(jī)多使用一年的時間。廂式壓濾機(jī)改進(jìn)成的自動壓濾機(jī)，更加的規(guī)整統(tǒng)一，利用將來的智能化推進(jìn)。更有效的保護(hù)濾布，使其使用壽命更佳長一些，自動清洗更方便一些。但是值得說一下是廂式壓濾機(jī)更換濾布更急復(fù)雜一些。在更換濾板時，標(biāo)準(zhǔn)統(tǒng)一，不用特殊的排列。再來說說板框壓濾機(jī)優(yōu)點：板框壓濾機(jī)過濾質(zhì)量更高，可以對濾餅進(jìn)行二次反洗，使得濾餅的純度更高。由于相對于廂式壓濾機(jī)，過濾空間更大，過濾效率更高，數(shù)度更加快。
