L&C’s PSA-1000 Testing Systems are customizable to broad ranges of gas flow rate and adsorbate bed size to meet your specific requirements, come with expert installation/training support .
These R&D Testing Systems offer L&C’s unique hardware configuration and proprietary software which simplify all levels of gas separation evaluations. Automated testing is provided over wide ranges of gas flow, temperature, pressure and vacuum, enabling the researcher to effectively and efficiently explore the complex “experimental matrix” of PSA and VSA studies.
The PSA System handles materials evaluations for activated carbons, zeolites, metal organic frameworks (MOFs), molecular sieve materials and more… and is especially effective for mixed-bed testing applications and the study of adsorbate poisoning and critical time-cycling.
System design and materials of construction permit the evaluation of all types of gases and adsorbate materials for chemical, petrochemical, gas purification and energy-related applications in academic, industrial and government R&D laboratory settings.
Based on application, various bed diameters are available. Bed diameter can range from 1” to 2” dia. to provide gas flow rate ranges down to 1 – 25 liters/min and up to 5 – 700 liters/min.
Based on application, various bed heights are available to provide required bed volume. Examples: Bed height as low 18” for a 1” diameter system provides approx. bed volume down to 150cc…while bed height of 72” for a 2” diameter provides approx. bed volume up to 3500cc.
Pressure range up to 1200psia (83 bars) with controlled vacuum testing down to .1 Torrs and general vacuum functions for desorbing of materials.

无机实验室合成的MOF,COF样品量通常都非常少,只有几百毫克级别的。传统意义上的分子筛,活性炭都具有大批量,合成量大的特点(样品量在公斤级别)。因此适用于评估MOF,COF等微量,少量样品的全自动小型的台式PSA/VSA正日益收到用户的关注。PSA300 LC正是按照用户需要设计并商业生产的小型全自动PSA/VSA仪器。仪器可以实时显示气体流量参数,压力,床体不同部位的温度和循环时间(Cycle time)。整个过程中的温度,循
利用多孔固体物质的选择性吸附,分离和净化气体或液体混合物的过程称为吸附分离。物质在吸附剂(固体)表面的吸附必须经过两个过程:一是通过分子扩散到达固体表面,二是通过范德华力或化学键合力的作用吸附于固体表面。因此,要利用吸附实现混合物的分离,被分离组分必须在分子扩散速率或表面吸附能力上存在明显差异。吸附分离是利用吸附剂对特定流体吸附和解析能力上的差异进行分离的。吸附过程得以实现的基础是固体表面过剩能的存在,这种过剩能可通过范德华力的作用吸引物质附着于固体表面,
吸附剂对于VOC的吸附,已经研究很长时间了。但是吸附剂对于不同类型的VOC的竞争吸附,以及吸附后脱附的解析过程的研究目前工作开展很少。 VOC研究通常应用于室内空气环境的研究。室内的压力为大气压。同时引入两组VOC气体到吸附剂里面,并且同时准确控制吸附剂床层的温度,压力。通过后期气体分析装置检测出吸附剂对于不同VOC的穿透曲线来研究吸附剂的选择性吸附,对于研究适合VOC吸附的吸附剂有显著的意义。
