An arrangement for preparation of a distillation measurement of a liquid includes a heater and a traversing system. The heater supports a perforated plate selected from a group of standardized perforated plates which further supports a container containing the liquid. The heater is enabled and controlled during the performance of a standardized test for determining evaporation properties of the liquid. The traversing system is adapted to traverse the heater and to interrupt a further traversing of the heater, if a pressure force of the perforated plate put onto the heater against the container reaches a threshold value.

The present invention describes a versatile, robust and environmentally controlled platform with a linear temperature gradient for massively parallel chemical or biochemical processing. This apparatus is capable of probing the phase transition behavior of macromolecules in solution, both thermodynamically and kinetically. This includesbut is not limited toliquid/liquid phase transition behavior of antibody solutions and in situ gelation of thermo-responsive polymers. The device can be operated in a multiplex fashion using a controlled temperature gradient architecture and visualized by dark field microscopy or by other optical intensity measurements.

Cryogenic device analysis systems are provided that can include: a cold source within a first vacuum chamber; a cryogenic device mount within a second vacuum chamber, wherein the first and second vacuum chambers are separated by a vacuum barrier; a first thermal conduit extending from the cold source through the vacuum barrier to the sample mount; a first thermal switch along the first thermal conduit and operatively aligned between the cold source and the vacuum barrier. Methods for performing analysis of a cryogenic device are also provided.

Fluid flow systems can include one or more resistance temperature detectors (RTDs) in contact with the fluid flowing through the system. One or more RTDs can be operated in a heating mode and a measurement mode. Thermal behavior of the one or more RTDs can be analyzed to characterize a level of deposit formed on the RTD(s) from the fluid flowing through the system. Characterizations of deposition on RTDs operated at different temperatures can be used to establish a temperature-dependent deposition profile. The deposition profile can be used to determine if depositions are likely to form at certain locations in the fluid flow system, such as at a use device. Detected deposit conditions can initiate one or more corrective actions that can be taken to prevent or minimize deposit formation before deposits negatively impact operation of the fluid flow system.

A system and method for distillation of a liquid sample at atmospheric pressure for the improved prediction of the heating necessary before the initial boiling point (IBP) of the sample is detected regardless of sample composition to ensure the IBP is observed within certain time constraints. A plurality of infrared (IR) sensors provides real-time temperature control in addition to a conventional measurement of vapor temperature. One IR-sensor monitors the liquid sample temperature in the distillation flask to obtain a corrected IBP time independent of the sample properties. Another IR-sensor monitors the temperature of the rising vapor column as the vapor rises up the neck of the distillation flask. Alternatively, an IR matrix may monitor the temperature of the rising vapor column. The system and method expand the scope of samples analyzed with improved signal, reproducibility, and test accuracy and still remain within the prescribed limits of a selected standard.
