Series 340 prepASH® Thermogravimetric Analyzer (TGA)
- Space for 29, 19 or 12 samples
- Readability of 0.0001 g and capacity 120 g
- Fully automatic thermo-gravimetric analysis operating at temperatures of up to 1000 °C
- Touch screen controls
- Complies with ASTM D7582
The Series 340 prepASH® thermogravimetric analyzer (TGA) automatically measures moisture, ash and loss on ignition at reduced workload and costs. The entire process is monitored and recorded from start to finish in a closed system. The prepASH is designed as an autonomous device and does not require any additional PC, it is available in 3 models.
Combining furnace, high precision balance and automation, the prepASH Series enables a huge reduction in workload through the simultaneous TGA analysis of moisture, ash and volatiles content. In one working cycle, 12, 19 and even 29 samples are dried and ashed fully, automatically.
Typical applications are analyses of thermoplastics, elastomers, thermosets, metals, ceramics and coal & coke (complies with ASTM standardized method ASTM D7582). The Precisa prepASH is also capable of analyses in the chemical, construction, food, animal feed, agricultural product and pharmaceutical industries. When determining sulfated ash, there is no need for critical handling with aggressive acids and the resulting acid vapors at high temperatures.
Thermogravimetric Instrument from Precisa
The TGA thermogravimetric analyzer works completely autonomously once it is loaded and started. This offers the user a completely new time management option as the thermogravimetric analysis can be run at different time periods which could not previously be used (e.g. at night). By the permanent recording of the measurements during the entire process and the automatic storage of the final results, the TGA test results are available at any time.
INTUITIVE TOUCH SCREEN CONTROL
prepASH thermogravimetric analyzer features a high-resolution colour touch screen (VGA 5.7”) which is simple and easy to use thanks to the language-independent icons. The sample chamber is opened and closed automatically by touching the icon on the screen.
DRY WEIGHT AND ASH
One of the most important parameters in thermogravimetric analysis is the testing of many materials and substances is the determination of dry weight and ash. This is often time-consuming and has a high error potential when performed in the classic way with drying/muffle oven and precision balance. This can be avoided using Precisa’s TGA thermogravimetric analyzer.
EFFICIENT DAILY ANALYSIS prepASH
With its easy operation is a fully automatic analysis system for thermo gravimetric determination of dry weight and ash. The prepASH intelligently unites the functions of a drying oven, muffle oven, analytical balance and evaluation unit into one system.
SULFATED ASH AS PER PHARMACOPOEIA
Ashing test procedures performed on pharmaceutical, polymer, and food samples frequently involve the use of sulfuric acid (H2SO4) . Hot sulfuric acid vapour released during these procedures is both hazardous to analysts and corrosive to equipment. In addition to these complications, sulfated ashing procedures are typically labour-intensive and time consuming, requiring manual fuming of acid from crucibles. In prepASH® sulfated ashing system, sulfuric acid fumes released from crucibles inside the furnace chamber are continuously removed, through a quartz tube connected in to a water cooled condenser with receiving vessel and to the acid scrubber module.
Quality Management Protocol
All 3 prepASH 340 Series thermogravimetric analyzers work autonomously as stand-alone-units and offer full control and documentation. They display the weight loss of each individual sample during the program steps and display these on the colour Touch Screen display. Beyond that all models can be connected though Ethernet interface to the network and be remotely monitored by means of prepDATA software on the PC. The results are calculated as losses or residuals in respect of weighing-in or pre-interval values (e.g. dry mass). The user may choose between %, ‰, g/kg, g.
