Scientific Solutions is the exclusive distributor for Quantachrome Instruments from Florida, USA who has re-released the formidable Monosorb Surface Area Analyser. The Monosorb has been a standard in laboratories around the world for determining the surface area of powders.
The Monosorb, a direct reading dynamic flow surface area analyser, now utilises a modified B.E.T. equation for rapid single point determinations of surface area.
The Monosorb requires as little as 6 minutes to complete an analysis, uses small quantities of sample resulting in short outgassing and analyses times. It utilises a modern and reliable method for rapid and accurate B.E.T. surface area measurements and does not require void volume measurements and ideal gas corrections.
The high degree of sensitivity of the Monosorb allows the use of samples weighing less than one gram and provides the measurement of surface areas as low as 0.1 square meters in the sample cell regardless of the adsorbate gas used. The upper range of the Monosorb is over 250 square meters in the cell. The reproducibility is better than 0.5%. The accuracy of the Monosorb is limited by the applicability of the single point method, which is usually better than 5% and on most samples errors less than 1-2% are possible.
The versatility of the Monosorb permits the user to choose the correct concentration of adsorbate to give results identical to the multipoint method. Many different adsorbates can be used in addition to nitrogen, such as, argon, krypton, carbon monoxide, carbon dioxide and other non-corrosive gases. A wider variety of sample cells are now available allowing measurements to be made on many diverse sample types.
With the push of just one button, the sequence of adsorption, warming of the sample cell, desorption and display of the surface area, all occur without operator intervention. The AUTOCALIBRATE feature guarantees proper calibration at all times. A built-in Flow Controller provides the ultimate in flow stability.
