Organic Inorganic Polymer Mineral Petrochemical Products Analysis
with Differential Scanning Calorimetry Machine
Application:
The DSC-500 is an intelligent, miniaturized, and integrated thermal
analysis instrument. It is applicable for analyzing key material
behaviors including melting, solidification, decomposition,
chemical combination, reduction, oxidation, and crystallization.
Additionally, it supports phase diagram construction and catalyst
R&D (research and development) — providing critical data for
material performance evaluation and formulation optimization.
Equipped with a user-friendly and efficient data processing system,
the DSC-500 features scientific calculation methods for core
thermal parameters. These parameters include epitaxial onset
temperature, enthalpy change, glass transition temperature,
enthalpy ratio, oxidation induction time (OIT), specific heat
capacity, and kinetic parameters. Note that the DSC-500A variant is
specifically designed for OIT testing.
This instrument serves as a reliable analytical tool for a wide
range of materials across industries, such as organic compounds,
inorganic materials, polymers, minerals, petrochemical products,
textiles, and pharmaceuticals.
Equipped with graph processing functions such as magnification and
zoom-out, it features an intuitive and user-friendly interface that
ensures straightforward operation — even for operators with basic
thermal analysis experience.
The instrument features:
1. Display System
Equipped with an LCD liquid crystal display with blue backlight, it
displays abundant information, including set temperature, sample
temperature, oxygen flow rate, nitrogen flow rate, differential
thermal signal, and the status of various switches—ensuring
comprehensive real-time monitoring of test parameters.
2. Communication Interface
The USB communication interface features strong universality,
stable and uninterrupted communication, and supports an automatic
reconnection function—guaranteeing reliable data transmission
during long-term testing.
3. Furnace Structure
- The furnace body adopts a compact structure with stepless
adjustable heating rate, meeting diverse temperature-rise
requirements for different tests.
- The entire installation process is optimized with a full mechanical
fixing method, which completely eliminates the risk of colloid
pollution inside the furnace affecting the differential thermal
signal—ensuring the accuracy of test data.
4. Dual Temperature Probe Design
This design ensures high repeatability of sample temperature
measurement.
- A temperature probe installed on the furnace wall is used for PID
control of the overall furnace temperature. However, thermal
inertia causes a certain deviation between the furnace wall
temperature and the actual sample temperature, and the deviation
varies with seasons.
- To solve this problem, an additional temperature probe is installed
at the bottom of the sample to measure its real-time actual
temperature. Combined with our proprietary temperature control
technology, the furnace wall temperature is adjusted to make the
sample temperature precisely reach the set value—greatly reducing
errors in both differential thermal signals and temperature
signals.
5. Gas Atmosphere Control
A digital gas mass flow meter enables automatic switching between
two gas atmosphere flows. It features fast switching speed and
short stabilization time—ensuring stable and reliable atmosphere
conditions during the test.
6. Calibration & Cooling
- Standard samples are provided for convenient calibration of
temperature coefficients by customers—simplifying routine
verification operations.
- A dedicated furnace cooling interface is designed to facilitate
rapid cooling of the furnace by customers, shortening the interval
between consecutive tests.
7. Software Performance
- The software adapts to computer screens of various resolutions,
automatically adjusting the curve display mode according to the
screen size. It is compatible with both laptops and desktops, and
supports operating systems such as Win2000, XP, VISTA, and WIN7.
- It supports user-programmable protocols to realize automated test
procedures. The software provides dozens of instructions, allowing
users to flexibly combine and save instructions according to their
specific test steps—simplifying complex operations into one-key
operations.
