Chemical Instrumentation Facility | Iowa State University Micromeritics' Gemini VII 2390 Series of surface area analyzers rapidly and reliably produces accurate and repeatable surface area and Open the catalog to page 2 Three Model Options Gemini VII 2390a The Gemini VII 2390a model is ideal for rapid and accurate surface area determinations by single-point and multipoint BET and Langmuir methods. Demonstration of how to use a BET from Quantachrome Instruments The Micromeritics 3Flex has the added capability to collect and display pressure & quantity adsorbed versus time measurements. Data are collected every half second. This application note is a tutorial on how to collect the data being transmitted over the Ethernet cable used for instrument communication using a client such as PuTTY or HyperTerminal.

Physi - 10 (Formerly 005-50) 40-point nitrogen adsorption isotherm (20 A to 3000 A) 370€ Physi -12 (Formerly 005-08) The ChemBET can determine total (BET) surface area with remarkable sensitivity. By flowing various mixtures of nitrogen and helium over the sample cooled with liquid nitrogen, the surface area can be determined from 0.1 square meters upwards. Using mixtures of krypton and helium the limit of detection is extended down to 0.01 square meters. 1. PURPOSE. The Micromeritics Tri Star 3000 Surface Area and Porosity Analyzer is used for N2 adsorption measurements. 2. SCOPE. Calculation of specific surface area from adsorption and desorption isotherm branch according to BET or single point method. Calculation
