WIKA威卡 233.50.160 RANGE 0 to 160 bar 一般來說，一般來說。齒間距離，齒數和轉速事影響螺桿式空壓機排氣量的主要因素。但是日常使用中的情況下確是以下的幾種情況。泄漏。因此就會發生氣體泄漏。壓力升高後的氣體通過間隙向吸氣管道及正在吸氣的嚙槽泄漏時，轉子之間及轉子與外殼之間在運轉時是不接觸的堅持有的間隙。將使排氣量減小。為了減少泄漏量，從動轉子的齒頂做有密封齒，主動轉子的齒根開有密封槽，端面也有環狀或條狀的密封齒。如果這些密封線磨損，將使泄漏量增加，排氣量減少;2.吸氣狀態。分離過程：樣品隨洗脫液的流動下移3.影響凝膠柱層析的主要因素層析柱的選擇與裝填層析柱的大小應根據分離樣品量的多少及對分辨率的要求而定。凝膠柱填裝後用肉眼觀察應均勻、無紋路、無汽泡。流動相──洗脫液的選擇：是含有濃度鹽的緩衝液，目的是為了防止凝膠可能有吸附作用。其選擇主要取決於待分離樣品，一般來說只要能溶解洗脫物質，並不使其變性的緩衝液都可用於凝膠層析。加樣量：加樣量的多少應根據具體的實驗而定：一般分級分離時加樣量約為凝膠柱床體積的1％－5％，而分組分離時加樣量約為凝膠柱床體積的1%-25%.凝膠再生：葡聚糖凝膠再生使用NaOH（.2M）和NaCl(.5M)混合液處理。
