IRSpirit Glove Box System Since IRSpirit can be controlled wirelessly, sample can be measured while the FTIR unit is installed in a glove box (custom order required). Communication is established via a wireless converter and a wireless router. Fig. 1 shows the schematic diagram of IRSpirit glove box system. Fig. 2 shows an example of a system where IRSpirit is installed in a flow-type glove box (Glovebox Japan, GBJA100). With this system, FTIR analysis can be conducted under an atmosphere of argon, nitrogen, etc.
