• a second transfer plate, the second transfer plate having a first side and a second side, wherein a second fluid channel is formed in the first side of the second transfer plate, wherein the first side of the first transfer plate faces the first side of the second transfer plate;
• and
• a CO2 permeable membrane disposed between the first transfer plate and the second transfer plate, wherein a portion of the first fluid channel and a portion of the second fluid channel are separated by the CO2 permeable membrane;
• providing a temperature-controlled enclosure, wherein the first transfer plate, the second transfer plate, and the CO2 permeable membrane of each of the plurality of transfer modules are at least partially within the temperature-controlled enclosure, the temperature-controlled enclosure comprising output and input ports for fluids to flow in and out of each transfer module,
• wherein the temperature-controlled enclosure comprises two shroud pieces that are attached along an interlocking lip enclosing the plurality of transfer modules and forming two end walls, a top wall, a bottom wall, wherein at least one of the end walls is insulated and wherein an insulating material is positioned between an inner side of the top wall and the plurality of transfer modules and between an inner side of the bottom wall and the plurality of transfer modules, said insulating material configured for insulation and sealing, wherein each of the plurality of transfer modules is at least partially held in place within the temperature-controlled enclosure by pressure exerted by the insulating material;
• measuring a temperature of the fluid within at least one of the first fluid channel or the second fluid channel of each transfer module using one or more temperature measurement devices;
• heating or cooling the fluid within the first fluid channel and the fluid within the second fluid channel of each transfer module to the desired temperature using a temperature control system, the temperature control system configured to heat or cool the first transfer plate and the second transfer plate of each transfer module to affect a temperature of the fluid within the first fluid channel and the fluid within the second fluid channel;
• and
• measuring i) a conductivity of the fluid within the portion of the first fluid channel separated from the second fluid channel by the CO2 permeable membrane and/or ii) a conductivity of the fluid within the portion of the second fluid channel separated from the first fluid channel by the CO2 permeable membrane using one or more conductivity sensors.
