SYSTEC原厂真空脱气泵，各种型号，适配各大进口品牌液相色谱仪和离子色谱仪，如安捷伦，赛默飞，Waters等。SYSTEC ZHCR VACUUM PUMP Introducing the ZHCR (Zero Hysteresis Constant Run) stepper motor driven vacuum pump, designed and developed for membrane degassing of HPLC mobile phase and other fluids used in Analytical Instrumentation. Employing a micro-stepping closed loop vacuum control strategy permits the pump to maintain a constant vacuum level set-point* by varying the RPM of the stepper motor. The pump initially runs at a high speed which provides for a quick pull down and, as it approaches the vacuum control point, the RPM is gradually reduced until the desired vacuum level is reached. This patented control strategy allows the On-Line Degasser to maintain a virtually constant vacuum that is unaffected by varying degassing loads. As a consequence, fluctuations in baseline due to vacuum hysteresis are eliminated by not having the pump repeatedly stop and start as is done in many older and existing systems

高效液相色谱日常维护要点-脱气
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。

泵仅依靠溶剂进入泵，在从比例阀转移到入口单向阀的过程中，发生的任何气体析出都会导致多种类型的错误。首先，会发生组分错误，因为传输线中的体积包含了空气，并不完全是流动相。随着传输线中气泡的伸展扩张，混合物的精度会继续下降。最后，进入泵的气泡可能会干扰入口单向阀，从而使泵无法将全部体积的流动相输送到色谱柱，而是将一部分移回比例阀。此外，在将流动相输送到色谱柱之前，泵也会将所有气泡压缩到系统压力。

液相色谱流动相脱气有哪些方法

对于液相色谱中流动相脱气你有啥认识？脱气方法都有哪些？常用的脱气方法是什么？

【原创大赛】液相色谱流动相脱气的那些事

液相色谱流动相脱气的那些事流动相脱气的必要性困扰液相色谱的一个很大问题是液路中常会溶入或进入气泡,均匀的、少量的还勉强可以接受,大气泡或是不均匀的气泡我们是绝对接受不了的。气泡的出现会使我们的分析不准确,甚至无法进行分析,给液相色谱分析的的朋友们带来不可估量的烦恼和麻烦。所以流动相的脱气在液相色谱使用过程中是必须的、必不可少的。脱气知识或技术也是大家应该了解或是掌握的。气泡在分析过程中出现很多不正常的现象,大致为: 1.气泡的存在会使压力变化大,流速不稳定或无液流； 2.气泡会延迟出峰时间和出峰效果； 3.气泡会使基线波动大,出现尖锐的噪声峰或漂移严重,从而影响仪器的灵敏度； 4.气泡进入系统排出需要时间,尤其是进入色谱柱.而且系统的平衡会被破坏,还得花费较长的时间重新平衡； 5.气泡严重时可能导致色谱柱的损坏等等 6.气泡可能还会使某些部件生锈及腐蚀; 7.某些色谱柱对流量、压力和温度要求非常严格,由于气泡带来的影响,色谱柱可能被损坏； 8.气泡还可能引起某些不稳定的样品被氧化或使溶液pH值发生变化； 9.气泡还可能引起一些我们无法预测的问题或是意外现象.出现气泡的原因一般有四种： 1.流动相溶液中往往因溶解有氧气或空气而形成气泡； 2.液路阻力比较大,吸液时出现了真空气泡； 3.系统开始工作时未能将流路中的空气排除干净； 4.在注入样品时混入了空气。对分析造成较大影响的主要是泵前形成的气泡, 为了消除气泡对液相色谱分析结果的影响，对流动相或泵前液路排气是非常必要的。液相色谱流动相脱气方式液相色谱使用较多的脱气方法主要有五种：氦气或氮气脱气、真空脱气、超声波脱气、加热回流脱气、在线脱气机脱气。 1.氦气或氮气脱气：氦气脱气是很有效的脱气方法,效果很好。由于氦气在流动相中的溶解度极低，所以用氦气脱气保护的流动相可以认为是一个无气体溶解体系。氦气缓缓的从储液器的底部通入流动相,赶去溶入的空气，如果使用得当，在10min内可除去80%～90%的溶入气体。如果存放流动相的储液器是密封的,并且通入有一定压力(5个psi左右)的氦气,脱气效果更佳。

【求助】液相色谱仪脱气不完全。

用的是岛津LC-20AD液相色谱仪，对流动相进行在线脱气，但脱气管道中总会有气泡去除不了，这样就使泵压不稳，请问各位大侠要怎么处理，有什么好的建议？谢谢！

Thermo液相色谱U3000脱气机真空泵
SYSTEC® ZHCR VACUUM PUMP Introducing the ZHCR® (Zero Hysteresis Constant Run) stepper motor driven vacuum pump, designed and developed for membrane degassing of HPLC mobile phase and other fluids used in Analytical Instrumentation. Employing a micro-stepping closed loop vacuum control strategy permits the pump to maintain a constant vacuum level set-point* by varying the RPM of the stepper motor. The pump initially runs at a high speed which provides for a quick pull down and, as it approaches the vacuum control point, the RPM is gradually reduced until the desired vacuum level is reached. This patented control strategy allows the On-Line Degasser to maintain a virtually constant vacuum that is unaffected by varying degassing loads. As a consequence, fluctuations in baseline due to vacuum hysteresis are eliminated by not having the pump repeatedly stop and start as is done in many older and existing systemsThermo U3000液相色谱仪脱气机真空泵，货号：6040.1981
