Research-Grade DSC At a QC Price.


A new differential scanning calorimeter calorimeter: see calorimetry.
calorimeter

Device for measuring heat produced during a mechanical, electrical, or chemical reaction and for calculating the heat capacity of materials.
 (DSC (1) (Digital Signal Controller) A microcontroller and DSP combined on the same chip. It adds the interrupt-driven capabilities normally associated with a microcontroller to a DSP, which typically functions as a continuous process. See microcontroller and DSP. ) is said to offer research-grade specifications for measuring heat flow of a sample as a function of temperature or time but at the price of a quality-control instrument. DSC 550 from Instrument Specialists Inc., Spring Grove Spring Grove may refer to:
  • Spring Grove, Illinois
  • Spring Grove, Indiana
  • Spring Grove, Minnesota
  • Spring Grove Township, Minnesota
  • Spring Grove, Pennsylvania
  • Spring Grove, Virginia
  • Spring Grove, Wisconsin
, Ill., costs $15,000 to $20,000 versus $25,000 to $40,000 for typical research models. It has two cell designs: the standard model 550 Nickel/Chromium and the ISI ISI International Sensitivity Index, see there  Constantan. The latter is said to be almost twice as sensitive as comparable cells on the market.

The DSC 550 operates from -120 C to +650 C with precision of 0.1[degrees] C and high reproducibility. Its design is said to minimize thermal "cross-talk" between the sample and reference sensor. Its Windows software controls the calorimeter, collects data, and calculates results. It allows for the measurement of glass-transition temperature, heat capacity, purity, transition enthalpies, and reaction kinetics kinetics: see dynamics.
Kinetics (classical mechanics)

That part of classical mechanics which deals with the relation between the motions of material bodies and the forces acting upon them.
. It features up to 10 program segments for combinations of heat, hold, or cool cycles.
