Heated HATR Flow Cells for ARK
The Heated HATR Flow Cell greatly extends the versatility of the ARK by allowing thermo dynamic studies of aqueous and nonaqueous liquids. The Heated HATR Flow Cell has the unique capability to allow samples to be analyzed at elevated temperature and pressure. The standard Heated HATR Flow Cell comes with a ZnSe 45° crystal that is ideal for a broad range of liquid samples, or a ZnSe 40° crystal, ideal for engine oil analyses. Other crystal materials and angles are available for optimization of specific applications and can be ordered in place of the standard crystals; however, not all materials are suitable for this cell. For example, Ge becomes infrared opaque and can be permanently damaged when heated above 50°C; therefore, call to determine the appropriate crystal material for the application.
