Both acetylacetone method and 3-methyl-2-benzothiazone hydrochloride（MBTH） method were used to quantitatively analyze formaldehyde emissions from wood-based panel products. The results showed that with 120 L of sampling volume, method detection limit（MDL） of acetylacetone was 0.007 mg/m ,3, which was relatively high for detecting low level（≤0.04 mg/m,3,） formaldehyde emissions. The results also showed that MDL of MBTH method was 0.0008 mg/m,3, with fast and sensitive reactions, which was suitable for detecting low level（,<,0.124 mg/m,3,） formaldehyde emissions according to GB 18580-2017.
