What are the detection limits for NH3 and DMF using the MoSe2/TiO2 composite sensor?

Label:chem

Topic
The study investigates the detection limits of the MoSe2/TiO2 composite sensor for NH3 and DMF under different humidity conditions. Detection limits are critical for assessing the sensor's ability to detect low concentrations of these gases.

From: "MoSe2-based room temperature gas sensor with a sub-parts-per-billion limit for ammonia and N,N-dimethylformamide", Mater. Adv., 2025,6, 2854-2866
Answer
The detection limits for NH3 are approximately 4.91 ppb at 40% relative humidity and 10.02 ppb at 80% relative humidity. For DMF, the detection limits are 7.82 ppb at 40% RH and 7.71 ppb at 80% RH.
