对表面化学和表面结构的了解对于催化材料的设计，生产和应用至关重要。这MicromeriticsChemiSorb Series analyzers combine the ability to perform both physical adsorption and chemisorption measurements in a low-cost and upgradeable system.
这basic ChemiSorb 2720 makes chemisorption (percent dispersion, active metal area, crystallite size, and surface acidity) and physisorption (single-point BET surface area, Langmuir surface area, and total pore volume) analyses affordable for even the most modestly funded laboratories such as teaching and research applications where owning an instrument had once been impractical. The instrument features dual ports, one for analysis and one for sample preparation. Standard features include a built-in sample cell cooling fan, four carrier gas inlets, a preparation gas inlet, and the optional capability to accommodate a mass spectrometer or other external detector. If analytical needs grow, the basic system can be upgraded to provide more capability.
Chemisorb 2750允许与Chemisorb 2720进行相同的分析，并具有更高精度，更快的吞吐量以及在适应各种实验方面的更便利性。通过暴露于大气的样品对准备的样品的可能污染是通过可用作样品分析端口或DEGA端口的双功能样品端口消除的。该仪器还包括注射隔膜外，还包括注射阀；循环很容易交换以提供不同的注入量。包括三个内置准备气体入口和四个载气入口。
An optional ChemiSoft TPx System (temperature-programmed controller and software) expands the capability of the ChemiSorb 2720 or 2750 to include: multipoint BET surface area, temperature-programmed reactions, data archiving, and advanced data reduction and reporting options.
