Code: #17863

Supplier: Rigaku Corporation

Simultaneous Thermal Analysis (STA) generally refers to the simultaneous application of thermogravimetry (TG) and differential thermal analysis (DTA) to one and the same sample in a single instrument. The measurement conditions are perfectly identical for the TG and DTA signals (same atmosphere, gas flow rate, vapor pressure of the sample, heating rate, thermal contact to the sample crucible and sensor, radiation effect, etc.). Rigaku adopts the horizontal differential triple-coil balance system which is the mainstream mechanism because the thermal drift which apparent mass change with increasing temperature becomes negligibly small.

    Software:
    1. Measurement data protection function
    During measurement, when a connection error occurs between the station and the module, the module will continue to perform the on-going measurement and the data will be stored in the module. The stored data is retrieved using a PC after the measurement, protecting valuable measurement data.
     
    2. End operation settings function
    The ECO mode or power OFF can be selected after the end of measurement. The temperature and time condition can be specified.
    We can select a variety of operation condition of the attached forced air-cooling fan such as cool up to room temperature, not in use on continuous usage.
     
    3. ECO mode
    After completing measurement, the ECO mode can be selected in the stand-by condition reducing the electricity consumption.
    Especially in TG-DTA, the ECO mode facilitates immediate transition from stand-by to stable measurement conditions.
     
    4. First aid function
    When an error or problem occurs in the module, the error number, error description as well as troubleshooting measures will be displayed facilitating a quick and smooth recovery condition. Also the error contents are stored in log files and can be readily sent to the technical service department for an immediate appropriate response.
     
    5. ASCII data import function
    Using the conversion software, the Thermo plus EVO2 analysis software can analyze carious ASCII converted measurement data.
     
    6. E-mail function
    The Thermo plus EVO2 can transmit information by email such as end of measurement, measurement data, occurrence of an error to PC, mobile phones thru corporate LAN connection abs can confirm the condition of an on-going measurement at remote locations.
     
    7. Excel, Word output
    From the menu directly, the measurement file can be directly exported in Word or Excel. Also, the output style can be modified thru the layout editing function. When exporting data in Excel, the numerical data will be automatically created in the worksheet 2 allowing a convenient data analysis in other application software.
     
    8. Instrument usage history listing function
    This function automatically records the module’s usage. Information such as date of usage, module name, operator, temperature program and measurement results are filed and saved in the achieve list. The history use of the module and the time of use are clear and effective for management and maintenance.
     
    TG-DTA accessories:
    HUM-1 Humidity Generator
    Combining a humidity generator (HUM-1) and a TG-DTA instrument equipped with an electrical furnace surrounded by a water-jacket enables
    TG-DTA measurements in a humidity-controlled atmosphere up to 80°, 90% RH. A polymer type relative humidity sensor and a high-precision temperature sensor are used as the thermal sensor to achieve quick variation of the humidity, as well as stability for prolonged periods of time.
     
    TG Smart Loader
    TG-DTA auto sample changer: Compact and smart. Simple system enabling condition setting in a single operation window.
    Different types of sample crucibles according to the applications (uses) are selectable.
     
    Features:
    ● Compact sample changer, minimizing installation space
    ● Conventional sample crucibles can be used without modification
    ● A single sample can be transferred during manual measurement (set and return key function)
    ● Faster and more efficient cooling, enabled with an optional proven cooling fan unit system
    ● Compatible with an infrared furnace system that provides high cooling efficiency
    ● Reliable operations realized by various sensors
    ● Single operation window for quickly setting measurement conditions, temperature programs, and the sample changer
