Carbon Dioxide Trap

Description

• General description: Sodium hydroxide nonfibrous silicate material is universally accepted for its high absorptive capacity and indicating properties for carbon dioxide. Typically, this material will absorb 20-30% of its weight in carbon dioxide before replacement of the saturated material is required. As carbon dioxide is absorbed, the greenish-brown material turns white because of the formation of sodium carbonate. The trap body is constructed of borosilicate glass, and the fittings are nickel-plated and have sintered stainless steel frits.A moisture trap should be installed downstream from this unit to absorb the moisture that is produced.Note: Exercise extreme caution when refilling the trap due to the caustic nature of the absorbent.Dimensions:100 cc Traps: 123/4 in. (32.4 cm) long x 13/4 in. (44 mm) diameter 250 cc Traps: 171/2 in. (44.4 cm) long x 2 in. (51 mm) diameter
• Application: It may be used to connect combustion oven and GCMS separator, for transfer of the gas into MS inlet system which monitors isotope-ratio.[1]
