Apollo SciTech's AS-C5 DIC analyzer is comprised of the same parts as the AS-C6L, except for the CO₂ detector. It uses a solid-state infrared CO₂ detector (LI-850, LI-COR, USA), which is incorporated inside the DIC analyzer. The model AS-C5 is more portable than the model AS-C6L, which uses the laser-based LI-7815 CO₂ detector connected on the outside of the main unit. It is available in a single port version (show below) or a multiple port version (see the page of model C6L).
