The #2T-AWT features our unique Advanced Window Technology to form a gas cell which can provide full range spectral access (NIR and MIR) for gases under combined high temperature (300degC) plus high pressure conditions (4000psi). Pathlength is set at a generally useful 2cm. The cell body is formed in a single piece of 316 grade stainless steel with excellent flow-through characteristics. Primary and Secondary windows are fully demountable. The Secondary Window stages are water cooled and gas pressurized, so allowing the primary windows to work at high pressure while at high temperature. The double chamber design also provides inherently greater safety for hazardous sample materials.
