Quantachrome NOVA 2200
NOVA is a surface area and pore size analyzing instrument. It features 2 degassing chambers with heating jackets capable of reaching > 300 °C and 2 analyzing chamber. It is capable of analyzing BET surface area and pore size of specimen.
It uses nitrogen as adsorbate to measure pore sizes up to 4 nm small and liquid nitrogen as coolant. Nitrogen can be replaced with carbon dioxide to detect even smaller pores in 0.4-4 nm range. It detects micro and mesopores, is a non-intrusive, non-destructive method.
