Dynamic flow gas sorption analyzer for extremely rapid BET surface areas
As a fully automated state-of-the-art dynamic flow system AutoFlow BET+ allows extremely rapid evaluation of the surface areas of solid samples. It performs single-point or multipoint determination of surface areas quickly and quietly on up to three samples simultaneously and independently. No vacuum pumps are required, reducing setup and maintenance costs while also eliminating time-consuming pump downtime and void volume measurements. The control module features a touchscreen and houses three built-in sample preparation stations. A PC software version which is 21 CFR Part 11 compliant is available for customers characterizing pharmaceutical samples.
Achieving Highest Throughput via Modular Design High throughput matching your analytical needs is achieved with one, two or three independent analysis stations.
Each AutoFlow BET+ analysis station provides highly accurate data by the implementation of:
(a) two built-in mass flow controllers, making the use of premixed gases unnecessary;
(b) a high-resolution MEMS-TCD sensor developed by Quantachrome Instruments; and
(c) precisely defined operating protocols.
The AutoFlow BET+ references all measurements to standard temperature and pressure (STP) conditions, thereby making them calibration-free and independent of ambient conditions. The design of the instrument and its control software makes the operation very robust and user-friendly, making it ideal for both QA and academic lab applications.
Assuring Extremely Rapid Surface Area Evaluations The AutoFlow BET+ can perform a typical 3-point BET measurement in less than 15 minutes per analysis station. Up to three independent analysis stations can be operated simultaneously for high throughput. The AutoFlow BET+ incorporates three different flow paths in order to optimize the analysis speed and resolution of samples covering an extremely wide range of surface areas.
The AutoFlow BET+ also incorporates a 3-station sample preparation module where three samples can be degassed under dry gas flow independently and simultaneously with analyses, using multi-step user-programmable temperature ramp-and-hold protocols for each sample.
