Abstract

The invention discloses a purifying column comprising a housing (1), sieve plates and an adsorption filler (6), wherein the sieve plates and the adsorption filler (6) are disposed in the housing (1). The purifying column is characterized in that the sieve plates are a first sieve plate (2), a second sieve plate (3), and a third sieve plate (4) in sequence from top to bottom; a filter layer (5) is disposed between the first sieve plate (2) and the second sieve plate (3); and the adsorption filler (6) is disposed between the second sieve plate (3) and the third sieve plate (4). By utilizing the above way, the purifying column provided by the invention is advantageous in that impurities in raw materials can be effectively removed; and all the raw materials flow into the adsorption filling material, and therefore the accuracy of analysis results is ensured.
