Picture of the LGA installed at a Biogas production facility in Southen Jutland, Denmark.
The LGA is designed with durability in mind to be employed in a harsh environment. The vulnerable parts, such as the mass spectrometer, are protected by an aluminium casing while keeping it relatively compact. This reduces the risk of damage from accidentally bumping into it.
Furthermore, the detector itself is self-cleaning to avoid biofilm growth. This can be seen in action here. The wetted components are surface treated and made of chemically resistant materials such as stainless steel 316 and SiO2, meaning that they can withstand the harsh chemical environment of the fermentation liquid.
