RELIABLE AND FLEXIBLE

ELTRA TGA analyzers are an ideal alternative to standard laboratory ovens and muffle furnaces for thermogravimetric analysis.Thanks to a programmable furnace that is connected to an integrated balance, heating and weighing are combined in one instrument. This saves time-consuming manual work and allows for high sample throughput. In addition, typical parameters such as moisture, ash and volatiles can be determined in one analysis run. The TGA Thermostep ML processes up to 19 different samples, typically weighing between 500 mg and 5 g, in one analysis cycle. The surrounding atmosphere and temperature of up to 1,000 °C within the heating chamber can be freely defined by the user during analysis to create a standard operating procedure. The crucible lids, covering of the samples, can be applied or removed manually during the analysis process to assure a standard compliant analysis of volatiles in coal and coke

HIGH-PERFORMANCE ANALYSIS TECHNOLOGY

The TGA Thermostep ML is a powerful thermogravimetric analyzer characterized by robust design, high precision and flexibility. It is possible to apply different atmospheres and to use sample weights of up to 5 g. The Thermostep reliably and efficiently measures parameters such as moisture, ash and volatiles according to a user-defined SOP.

PURGING GAS


The TGA Thermostep is very flexible with regards to the purging gas used. At each stage of the analysis either nitrogen, oxygen or surrounding atmosphere can be selected. In the latter, the surrounding atmosphere penetrates into the TGA Thermostep, gently oxidizing the samples.

TEMPERATURE CONTROL


The furnace temperature is monitored by two thermocouples which are not encapsulated. One thermocouple monitors the temperature inside the furnace, the other monitors the temperature within the heating element. Due to the absence of the encapsulation the heating can be controlled quickly and precisely.

ENCAPSULATED WEIGHING CELL


The latest TGA Thermostep generation features an encapsulated weighing cell with 0.1 mg resolution providing highly precise measurements. The encapsulation isolates the weighing cell from the ambient atmosphere and is extremely stable. The weighing cell is connected to the furnace by a ceramic spindle with pedestal on which the crucibles are placed.

SIMPLE OPERATION YIELDS QUICK RESULTS

Operation of the TGA Thermostep ML is simple, convenient and safe. After selecting the Standard Operating Procedure (SOP) in the PC, the sample ID’s can be entered into the software. The samples are then weighed in the crucible at the position assigned to the sample ID in the carousel. After one sample has been weighed, the carousel automatically rotates to the next position and the next registered sample can then be weighed in the crucible.

Alternatively, a carousel filled with samples which has been weighed externally, can be placed into the analyzer. Once the analysis is finished, a new cycle can be started after a short cool-down period.

APPLICATIONS

Due to the flexible application management the TGA Thermostep ML can measure TGA parameters in many samples like coal, coke, building materials, food

ANALYSIS OF FOOD

The TGA Thermostep can determine the parameter moisture, volatile and ash in one analysis cycle due the automatic placing and removing of lids. The TGA is compliant to ASTM D 7582.

Building materials require the measurement of moisture and loss on ignition (LOI). The LOI can indicate the presence of organic matter or carbonates.

Some foods like pet foods, bisquits, or milk require the measurement of dry mass and ash content. Due to the encapsuled weighing cell even the ash content of fluor could be measured safe and precise.

FUNCTIONAL PRINCIPLE

Operation of the thermogravimetric analyzer TGA Thermostep is simple and convenient. The measurement process has to be defined once regarding the used temperatures, atmospheres and heating ranges. To start the thermogravimetric analysis, a predefined process simply has to be chosen in the software and the sample has to be weighed into the crucible. All further steps are processed automatically. All data processing, control of the measurement process and calculating of the result is done by an external PC with Windows®-based software. Thermogravimetric analysis of moisture, volatile and ash content requires about 4 hours.
