The use of mixture and pure gas adsorption isotherms for further calculations and predictions using 3P mixSorb
3P Instruments offers two general ways to obtain information about mixed gas adsorption processes; first with the measurement of the dynamic sorption process with the mixSorb L by 3P Instruments and second by use of the 3P sim software of the mixSorb L to calculate mixed gas data using pure gas isotherms.

Super-ambient pressure gas separation studies using 3P mixSorb coupled with mass spectrometer
The 3P Instruments mixSorb L coupled with a mass spectrometer offers the ability to study the adsorption behavior of the components of ternary gas mixtures and can be used as an experimental tool to optimize porous materials for specific gas separation applications. Such valuable performance characteristics can only be derived from dynamic experiments.

Breakthrough curves on carbon molecular sieves – experiment and modeling using 3P mixSorb
The dynamic method for the measurement of gas adsorption breakthrough curves is necessary to estimate kinetically controlled sorption processes which cannot be predicted by thermodynamic simulation. The 3P Instruments mixSorb L can be used for such practical investigations to obtain relevant data for kinetically controlled pure and mixed gas sorption dependent on temperature, pressure and gas flow.

Determination of breakthrough curves and effective gas sorption capacities
Fully automatic gas sorption analyzer, the mixSorb L, from 3P Instruments is a sophisticated analyzer that effectively closes the knowledge gap between equilibrium BET and pore size measurements of porous materials and the dynamic determination of their effective sorption capacities.

3P Instruments DT series particle size and zeta potential using acoustic and electroacoustic spectrometry
This brochure introduces the 3P Instruments DT series of acoustic and electroacoustic spectrometry instruments.

3P Instruments DT-700 electric conductivity of organic solvents and dispersions
The 3P Instruments DT-700 measuring cell consists of two coaxial stainless steel electrodes and a guard electrode. The task of the latter is to eliminate leakage currents between the measuring electrodes. For easy cleaning after analysis, the outer hollow cylinder electrode can simply be pulled off.

3P Instruments Altamira series
The AMI Chemi family of instruments combines a variety of temperature-programmed techniques, including: temperature-programmed desorption (TPD), temperature-programmed oxidation (TPO), temperature-programmed reduction (TPR), and temperature-programmed reaction (TPRx). The AMI Chemi family of instruments can also perform pulse chemisorption, dynamic BET and gas-phase iso-thermal reaction experiments.

Secrets of particle size analysis for pharmaceutical preparation and raw material by 3P Instruments
The improvement of drug quality is the basic principle for developing overall strategies. For the current evaluation system, dissolution is a top priority, and the particle size of the pharmaceutical preparation has an important influence on the dissolution curve. However, everyone still faces a lot of confusion about particle size analysis. This note sheds some light to this issue.
