Research on the Seed Respiration CO₂ Detection System Based on TDLAS Technology

Table 1

Performance comparison between seed respiratory CO₂ detection system with two commonly used CO₂ detection methods.

	Detection limit	RSD	Typical measurement frequency	Reference
NDIR CO2 sensor	30 ppm–50 ppm	0.03	0.1 Hz	[33, 34]
Gas chromatography	0.8 ppm–1.5 ppm	<1.5	About 0.001 Hz	[35, 36]
Seed respiratory CO2 detection system^a	1.23 ppm	0.00046	About 0.2 Hz
