What are the minimum detection limits of the microLGD ?
The detection limit is different for each gas. However, the detection limit can be lowered by increasing the physical size of the absorption path (twice the absorption length gives a detection limit lowered by a factor of two), or by increasing the measurement time (signal-to-noise increases with the square-root of the measured time, i.e. measuring 100 times longer gives a detection limit lowered by a factor of 10). A list of minimum detection limits, based on a measurement time of 1 second is given below.
