AccuPyc II

The AccuPyc II Series of Pycnometers (Gas pycnometer) provides high-speed, high-precision measurements for determining the true density of powders, solids, and slurries. The analyst enters the mass of the material and then with a few keystrokes the measurement is initiated, several measurements are performed, and the density of the material is displayed.  

Gas pycnometry is recognized as one of the most reliable techniques for obtaining true, absolute, skeletal, and apparent volume and density. This non-destructive technique utilizes the gas displacement method to measure the volume of a material. Inert gases, such as helium or nitrogen, are commonly used as the displacement medium for gas pycnometry. Density determinations from the gas displacement method are more accurate, reproducible, and faster than the traditional Archimedes water displacement method.

ASAP 2020 Plus

The ASAP 2020 Plus is a high-performance adsorption analyzer for measuring surface area, pore size, and pore volume of powders and porous materials.  Standard methods or user customized protocols can be used to characterize adsorbents, catalysts, zeolites, MOFs, APIs, excipients, and a wide variety of porous and non-porous materials.  The ASAP 2020 Plus is ideally suited for gas  adsorption analysis of microporous (0.35 to 2nm) and mesoporous (2 to 50nm) materials and delivers superior accuracy, resolution and data reduction.  A vapor sorption option can be added to the ASAP 2020 Plus to extend the analysis range of the ASAP 2020 Plus physisorption. 

A chemisorption option extends the application range of the ASAP 2020 plus to both physical and chemical adsorption for characterizing the texture and active surface of catalysts, catalyst supports, sensors and a variety of other materials.

AutoChem II & HP

The Autochem II Series has been designed after years of experience by Micromeritics in the field of basic and advanced catalysts characterization for catalytic surface activity. Micromeritics is recognized in combining applied scientific innovation for many customers analytical requirements, even for the most demanding conditions.

Autochem II provides accurate and fast results applying chemisorption techniques in isothermal conditions on metal dispersion, exposed metal surface area and aggregate size, surface acid/basic sites quantification. When applying temperature programmed techniques like TPR, TPO, TPD and TPSR one can perform deep investigation on reduction / oxidation properties, determine the probe gas-solid activation energy or quantify the number and species of surface-active sites.

Complex characterizations are made easy by the Autochem II HP specifically designed to run experiments starting from atmospheric pressure up to 1000 psia (6.9 MPa), investigating the behavior of catalysts in conditions similar to real manufacturing plants. The standard detector is a high precision, high sensitivity, high linearity, and corrosion resistant TCD that can be integrated and coupled with an external detector like a mass spectrometer for selective gas monitoring. Signals are easily synchronized by the MicroActive control software. The Autochem II series can be equipped with a number of options to expand the analytical possibilities Cooling options include the Kwikcooler a Kwikcool Vortex device, and a CryoCooler II cryogenic option that expands the temperature range from –100 °C to 1100 °C. There are additional options including one of the most precise vapor generators available on the market.

Features And Benefits:

• Separate  circuits for sample preparation and analysis 

• Avoids the risk of tubing and detector contamination in case of release of corrosive gases during high temperature treatments 

• Independent mass flow controllers for the reference and analysis channels of TCD in the Autochem II 2920 

• This unique approach allows a completely automatic and precise quantitative calibration of the TCD signal for TPR,TPO and TPD experiments, covering in one run the complete range of reactive gas percentage in the inert carrier. Quick, fast, precise and easy. 

• Selectable temperatures of TCD and filaments  

•  Long lifetime of filaments because the TCD works at constant and selectable temperature avoiding the risk of burning. In addition, the TCD sensitivity can be improved when testing low metal percentages catalysts by increasing the temperature difference between the filaments and the monolithic block
