TG 209 F1 Libra® Thermogravimetric Analysis - TGA Method, Technique and Applications Analyzing & Testing

TG 209 F1 Libra® Convincing Technology Controlled by Intelligent Software

Vertical Design Combined with Top-Loading Ultra-Microbalance for Easy and Safe Handling The design of the vacuum-tight TG 209 F1 Libra® ensures free and safe access to the sample, easy crucible exchange (no hang-down wires or horizontal balance beam), and a constant and stable position for the sample carrier in the furnace. This results in homogeneous temperature distribution and high sample-to-sample reproducibility. Robust Ceramic Furnace for Fast and Reliable Quality Control The maximum temperature of the corrosion-resistant micro-furnace amounts to 1100°C (sample temperature). Its high...

Micro-Furnace -A Dynamic System for Efficient Laboratory Work The low-volume furnace of the NETZSCH TG 209 F1 Libra® supports fast heating rates over the entire temperature range and fast ballistic cooling by chilling from 1100°C down to room temperature. The low purge gas flows ensure less dilution of the evolved gases (to be considered if coupling to evolved gas analysis is planned). The short gas path, low volume of the furnace and low dead volume above the sample help prevent condensation of the evolved gases in the furnace. Precise Detection of Sample Temperature The sample temperature...

The Right Sample Carrier for Any Application Various sample carriers are available including corrosion-resistant sensors, high-sensitivity c-DTA® sensors for improved monitoring of endo- and exothermic effects, and special sensors for large sample masses. The sample carrier can be changed out in less than one minute. Sample carrier made of Al2O3 for corrosive gases and sample carrier type P for c-DTA® Interchangeable Sample Carriers1 Application Standard TGA Ideal for c-DTA® For corrosive media Material of Sample Carrier Al2O3 Platinel® Al2O3 Sensor Type Type P Type P (disk) Type P,...

Vacuum-Tight by Design for Reproducible Measurement Conditions Defined Gas Conditions for Reproducible Measurements The vacuum-tight design allows a pure and defined inert gas atmosphere to be established for the pyrolysis of the sample. No superimposed oxidation by residual air can occur. The integrated gas supply unit with mass flow controllers (MFCs) accommodates up to two purge gases and one protective gas. They can be controlled, recorded and evaluated via the software. AutoVac -Reproducible Results The AutoVac* feature allows for software-controlled automatic evacuation and gas...

Thermogravimetry Was Never as Efficient as Today - Routine Work and Out-of-Turn Measurements Run Side by Side. A novelty in thermogravimetry is the automatic sample changer (ASC); it comes with two disposable trays in microplate format for 96 samples each which can be quickly inserted and removed. This allows for measurement of up to 192 samples. An additional fixed strip is reserved for up to 12 calibration materials or empty crucibles of different dimensions and materials for calibration and correction purposes. Of course, correction measurements with empty crucibles can also be taken on...

CHANGER Automatically Controlled Tray “Remove Lid” Function Cover Protects Samples from of the ASC Keeps Your Dust, Humidity and Sample in the Crucible Atmospheric Influences Both trays are immediately covered after the 4-needle gripper has removed or repositioned a crucible. After closing the tray depots, the space can be purged by branching gas channels integrated into the cover. Directly after closing, the gas flow is increased and decreases if the cover remains closed. This entire process takes only a few seconds. In addition, a “remove lid” feature comes with the instrument. Placing a...

SmartMode -Run Professional Tests After Minutes of Introduction SmartMode boasts a clear structure, a consistent navigation design and easy-to-access buttons. Using wizards (measurement templates), it is possible to start a measurement with just a few inputs. Alternatively, customized methods or predefined methods can be selected to start an experiment. The predefined methods are based on different standards or measurements under reduced pressure. Even customers unfamiliar with the software immediately know how to proceed. ExpertMode -Perfect for Beginners and Professionals For those who...

AutoEvaluation - Identify - A Step Ahead Autonomous Evaluation with the Database AutoEvaluation is a self-acting software package which evaluates the thermogravimetric effects, i.e., mass changes (decomposition reactions) without using stored evaluation macros. For all those who haven't seen such measurements yet, AutoEvaluation will handle the curve independently - without any effort on the operator's part. The Identify software searches for similar results stored in libraries, providing instantaneous interpretation of the measurement at hand. With the Identify software package, it is...

BeFlat®– Measurement Results Quickly Obtained 200 No More Baseline Run – Get to Your Results Faster In contrast, the TG 209 F1 Libra® generally no longer requires a separate baseline run. This greatly simplifies routine test work, especially for quality control in industry. rk – of wo tion orrection lifica c Simp f-the-art -o state In order to ensure correct mass change values, a baseline run is typically carried out under identical test conditions such as heating rate, gas type, gas flow rate, crucible type and geometry, etc., and subtracted from the sample measurement. The baseline takes...
