Why Controlling The Temperature of the Sample Interface Matters

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.

Do you know when to use a flow cell instead of an insertion probe

Do you know when to use a flow cell instead of an insertion probe?

Our Guided Wave Multi-Purpose Flow Cells (MPFC) are used whenever direct insertion probes are not appropriate and the process material does not require the added assurance of the High Safety Flow Cell. One of the primary advantages of near infrared process spectroscopy is the utilization of intrinsically safe fiber optic cables to remotely locate the probe. While direct insertion probes eliminate sample loops and sample systems and their associated problems, sometimes it is necessary to install sample loops for safety, service, and/or sample conditioning reasons. Our MPFC is a convenient, compact, rugged sample interface that is easy to install and even easier to service. The cell’s sapphire windows can be cleaned by simply removing a clean-out plug for direct access to the windows without disconnecting process lines or fiber optic cables.
