Instrument Introduction:

New generation gas adsorption analyzer from Kantar Instruments, USA

——The beginning of a new era in the field of adsorption

The latest product developed by Kantar Instruments in the United States, Autosorb-iQ, represents the highest level of fully automated and multifunctional integration in the industry. What Autosorb iQ is going to tell you, such as steam adsorption, dynamic/static chemical adsorption, dual station parallel ultra microporous/ultra-low specific surface area analysis, etc., is that if you can think of it, I can do it!

As a leader in the field of gas adsorption, Konta Instruments has never stopped moving forward. Until the recent release of the new generation gas adsorption analyzer, Autosorb-iQ, it announced the arrival of a new era to the world. Multi functional integration, modular design, ultra-fine microporous analysis, TPR/TPO/TPD chemical analysis, and mass spectrometry capabilities, among many others, will prove to you that Autosorb iQ is not an instrument, but your versatile helper!

The Autosorb iQ is not a simple technological upgrade on the well-known gold grade analytical instrument Autosorb-1, but a groundbreaking product developed based on the latest adsorption theory, the most advanced digital pressure sensing technology, and the simplest human-machine interaction system.

Main features:

On March 1, 2010, Quantachrome Instruments U.S. officially launched its milestone product, Autosorb iQ, in the field of specific surface area and pore size analysis. The Autosorb iQ is not a simple technological upgrade on the well-known gold grade analytical instrument Autosorb-1, but a groundbreaking product developed based on the latest adsorption theory, the most advanced digital pressure sensing technology, and the simplest human-machine interaction system.

Compared to the traditional Autosorb-1, the Autosorb-iQ has the following characteristics:

1. Higher analysis throughput - Traditional Autosorb-1 can only analyze one sample in real-time during microporous analysis, while the analysis time for an ISO/GB standard microporous sample is between 30-60 hours. For samples with complex pore structures such as activated carbon, this analysis time will be even longer. Therefore, the continuous analysis volume of one Autosorb-1 for one month is about 12 samples. However, Autosorb iQ can analyze two microporous samples simultaneously, greatly improving its analytical capability, with a monthly analysis capacity of over 20 samples.

2. Higher pressure measurement accuracy - The dual station Autosorb iQ not only adds an additional analysis channel on top of the single station. But instead, an additional analysis system was configured on top of the original single station analysis system, which means an additional high-precision pressure sensing analysis component was added, including one 1000torr, one 10torr, and one 1torr pressure sensor. The number of pressure sensors has increased to 8. The Autosorb IQ XR with higher measurement accuracy is equipped with a 0.1torr high-resolution pressure sensor, which is suitable for studying the high stability of microporous adsorption below P/Po<10-6.

3. Stronger human-computer interaction capability - The preprocessing (degassing) part of Autosorb iQ is also completely controlled by computer software, which can be programmed for processing time, processing temperature, and evacuation rate to achieve fully automatic temperature control of the preprocessing program. Furthermore, the fully automated computer program processing from preprocessing to analysis has been achieved.

4. Longer analysis time - Autosorb-iQ provides users with a 3-liter high-capacity Dewar flask option, which can be continuously tested for more than 90 hours with a single liquid nitrogen filling. This provides necessary hardware conditions for users who study pore structures rich in activated carbon materials, composite molecular sieves, etc.

5. Unique remote control capability - the host can directly access the internet to achieve remote control and monitoring. The complete independence of testing and analysis has been achieved, providing convenience for the construction of advanced standardization laboratories and special toxic, harmful, and radiation analysis industries.

6. More adsorption gas links - The gas input interface of Autosorb iQ is designed with 5+7, which means the standard configuration is 5 analytical gas input ports, but can be increased to 12 ports according to user needs. Therefore, it is possible to achieve computer automatic switching analysis of 12 gas analysis channels, which facilitates the use of multiple gases to study the adsorption and desorption properties of materials.

7. More expansion module interface design - based on the Autosorb iQ basic model, it can be linked with TCD, mass spectrometry, Oxford variable temperature system, and calorimeter system. Implement various functions such as program temperature rise experiments, analysis of gas composition generated by reactions, and study of adsorption heat.

8. More powerful data processing capabilities - the relative pressure points required for calculating the specific surface area can be selected through intuitive graphical methods, completely solving the problem of correctly selecting points in the calculation of the specific surface area of microporous materials. At the same time, all 22 DFT kernel files used for different research purposes such as N2 adsorption, Ar adsorption, CO2 adsorption, etc. are open to users for free, which can meet various research needs.
