色谱脱气方法

大家好，高效液相色谱和其它常规分析仪器一样，为了能让高效液相色谱更好的工作、在实验的时候得到可靠的数据，首先你要保养好它，使它处于一个健康的待机状态，这样你使用它进行检测分析时就可以比较顺利地获得理想结果。而且良好规范的操作习惯还可以延长仪器使用寿命。在日常使用维护中最重要的主要有三点：脱气、过滤和冲洗。这三点属于最常规操作要求，同时也是检测分析中必不可少的流程。小编会分三期为大家讲解，今天先带大家了解下脱气的具体原因和脱气的具体方法。脱气流动相里存在气泡是HPLC系统操作过程中常见的问题、气泡会造成泵输出的问题，也能造成检测器的输出结果中出现假的色谐峰。大多数的气泡问题可以在使用流动相之前以脱气的方法来消除。下面就是小编简单总结了脱气的主要目的：1、防止由溶解（在液体中的）气体量的变动引起的检测不稳程度 。2、提高保留时间和色谱峰面积的重现性。3、防止气泡引起尖峰。4、使基线稳定，提高信噪比。5、防止由气泡的产生引起的故障，示差折射率检测器：使折射率变化UV检测器（200nm以下）：溶解氧气有吸收，荧光检测器：溶解氧气有消光作用。6、减少死体积。7、防止填料氧化。脱气要求只要空气在流动相里保持溶解，气泡问题就很少会出现。原则上讲人工配备的等度洗脱流动相般不需要脱气就可以在实验中使用，但是被气体饱和的溶液也只需要非常小的压力下降就能脱气。比如当流动相通过溶剂人口的在线过滤器，或者当流动相进人压力相对低的检测器溶液池时。因为这个原因和为了能使一般的HPLC操作具有可靠性，我们强烈建议用于反相色谱的所有溶剂都必须经过脱气。脱气对于正相HPLC来说不会产生很多问题，所以使用正相色谱时脱气是可选的。需要除去的溶解在流动相里的气体量根据HPLC泵的设计不同而不同，一些泵能够承受大量溶解在流动相里的气体而另外些泵则需要彻底脱气才能达到可靠的操作效果。常用的脱气方法1.抽真空脱气法：此法可使用真空泵，降压至0.05～0.07MPa即可除去溶解的气体，用真空脱气10-15分钟可以除去60%-70%溶解在流动相的气体。但是由于真空脱气会使混合溶剂组成发生变化，从而影响到实验的重现性，因此多用于单溶剂体系的简单分析。2.氦气喷洗脱气法：氦气喷洗是除去流动相里的气体最有效的技术，主要是利用氦气在液体中溶解度比空气低的特性，在0.1MPa压力下，以约60mL/min流速通入流动相储液容器中10～15min，可以很有效地从流动相中排除溶解的空气，能排除接近80%-90%溶解的气体。采用一个高效分布式喷射流装置，一体积的氦气可从流动相中将等体积的几乎全部气体排除。3.在线脱气法：在线脱气主要优点是操作简单，低故障，并非常有效。4.加热回流法：此法的脱气效果较好。但是还是有一些不足，那就是在操作时要特别注意冷凝塔的冷却效率，否则溶剂会丢失，混合流动相的比例会有变化。5.超声波脱气法：实验室最普遍的脱气方法，主要操作就是将欲脱气的流动相置于超声波清洗器中，用超声波震荡时间不宜过长，避免温度升高导致易挥发性成分的丢失，一般在5min之内。但是相对于其他脱气方法，优点是容易操作，时间短。不足之处则是此法的脱气效果相对较差。到此需要脱气的具体原因和脱气的具体方法，在这里就差不多介绍完了。下期小编将继续带领大家去具体了解高效液相色谱日常维护要点-过滤。
