C-Sorb 300 Chemisorption Analyzer Features

The C-Sorb 300 chemisorption analyzer is a fully automated catalyst characterization instrument wherein the LabVIEW-based software is used to switch gas streams, control gas flow rates, blend gases, control temperatures, control ramp rates, and to collect all the data needed to quantify the adsorption and desorption of gas molecules on the surface of a catalyst. An “Overview” screen shows the status of the unit at a glance, providing information on the position of all valves, type of gas connected to each port, temperatures, and detector signal. Lines change color to illustrate the current flow path. In manual mode any valve can be switched just by a click of the mouse on its icon. Gas flow and temperature setpoints can be entered from this screen.The most sophisticated data handling package in the industry is included which allows the user to display and integrate signal peaks, calculate chemisorptive parameters, peak fit, and overlay data.

The C-Sorb 300 chemisorption analyzer is fully automated and computer-controlled for ease of operation and reliability. It is designed so that experiments can be run on an unattended basis. This PC, supplied with a Windows based operating system, can be networked and is capable of managing other laboratory tasks in addition to operation of the instrument. 

The control and data acquisition functions are performed by LabVIEW applications software. Using this software, a complete experiment can be set-up in minutes, and it can be saved for future use or modification. 

The control portion of the software controls and regulates all valve positions, temperatures, flow rates, and detector parameters. The software also allows for the use of an alarm matrix. Data acquisition occurs at a selected rate for optimum performance. 

• Various Detectors

The C-Sorb 300 chemisorption analyzer comes standard with a highly linear TCD. In addition to the TCD, we also have been delivered with a wide range of auxiliary detection devices.

Choices of auxiliary detectors have included:

1. Mass Spectrometer: GC with FID/TCD/FPD

2. Flame Ionization Detector: FTIR

Any detector that provides an analog output or which can communicate through DDE, Serial ports, OPC, ActiveX, or other Windows protocols can be triggered by the C-Sorb 300. The degree to which the auxiliary detection device is to be integrated with the instrument can be specified and incorporated into the control software.

• Gas Blending

The C-Sorb 300 chemisorption analyzer comes standard with gas blending capabilities that avoid any need to purchase expensive gas blends to conduct experiments such as TPR or TPO. It includes an auxiliary gas line by means of which a gas can be mixed with the carrier gas to provide custom-blended gases. An in-line static gas mixer assures homogeneity of the resulting blend.

The gas blending capability also facilitates the use of the C-Sorb 300 as a gas-phase, atmospheric reactor.

C-Sorb 300 Extended Models for Chemisorption

	C-Sorb 300HP: C-Sorb 300HP is a high temperature and high pressure chemisorption analyzer for higher scientific research needs. ln addition to the basic experiments that can be done with C-Sorb 300,  the performance of catalysts can be further investigated at high pressures. This model of instrument can be tested from atmospheric pressure up to 100 bar.
	C-Sorb 300lR: Chemisorption and thermal desorption techniques, such as TPD (temperature programmed desorption), have been widely used for the characterization of cataIysts. These techniques rely solely on the observation of evolved gases from a catalyst surface as detected by a thermal conductivity detector (TCD) or, in some cases, a mass spectrometer. With these techniques it is possibIe to learn about the number and strengths of sites but not about the nature of the sites, the type of adsorption, or whether there exist multipIe types of sites. ln order to overcome this drawback, we developed the C-Sorb 300lR which combines all the standard model's techniques with real-time observation of the catalyst surface by Fourier Transform lnfrared (FTlR) spectroscopy. This combination of techniques allows for the direct observation of the adsorbed species and thus expands the knowledge of the nature of the adsorption/desorption process.
	C-Sorb 300TKA: The Steady State Isotope Transient Kinetic Analysis (SSITKA) is an effective method to study the kinetics and mechanism of heterogeneous catalytic reaction. This technology can not only qualitatively obtain the information about the reaction mechanism, but also obtain the quantitative in-situ kinetic information, including the amount, coverage, surface life of intermediate species adsorbed by different reactions, the rate constant reflected by primitives, the number and distribution of active sites and so on. ln order to meet the needs of users, through years of technology accumulation, we have launched C-Sorb 300TKA equipment, which can be perfectly suitable for such reactions and provide our customers with reliable and efficient testing equipment.
	C-Sorb 300S: We are constantly encountering requests for reaction units and characterization equipment that can handle reactants and/or products that are corrosive, reactive or unstable. We typically consider these to contribute to a “harsh” environment for our testing equipment. C-Sorb 300S can effectively address this concern. The anti-corrosion treatment is completed inside the instrument to ensure that the instrument can conduct experiments stably and for a long time even in a "harsh " environment.
