WHY CONTROLLING THE TEMPERATURE OF THE SAMPLE INTERFACE MATTERS

Some applications such as nucleation reactions, polymer cross-linking or high viscosity fluids require that the temperature of the fluid be precisely controlled to ensure that the reaction proceeds as expected and passes through the flow cell. If the temperature drops, the fluid may solidify in the flow cell or the polymer chain may not be the correct length.

You Need To Consider A Temperature Controlled Flow Cell for At-Line FT-NIR Measurements

Our Guided Wave Multi-Purpose Flow Cell (MPFC) that is compatible with NIR and UV-VIS Analyzers is available with internal tubing for heating or cooling fluid. While the heat exchanged is not sufficient to impact a rapidly flowing sample, it can be used to maintain the temperature of a preconditioned sample.  A version of the MPFC, drilled to accept a heating or cooling fluid, is also available. While the heat exchanged is not sufficient to significantly impact a rapidly flowing sample, it can be used to maintain the temperature of a preconditioned sample.

The MPFC provides exceptional optical performance and is optically matched to all our Guided Wave analyzers Typically, peak transmission exceeds 50%. That means more signal, lower measurement noise translating to lower limits of detection.
