The prepASH 340

series consists of a muffle furnace combined with an analytical balance and advanced software using a touch-screen user interface. Weighing curves are recorded over time for each test sample. This permits automatic end-point determination and control during the entirety of the drying and ashing process. No additional computer is needed.

Easy method development with prepASH

Definition of a temperature profile

Temperature curves can be individually configured and consist of more than 10 freely definable steps (ramping/holding). Temperatures can be set between 50°C to 1000°C. Combustion atmosphere can be varied by choosing the process gas (air, O2, N2).

Setup of the end-point determination

The analysis is finished when all samples have reached a stable weight. The auto-stop criteria can be chosen from 0.1-9.9 mg per 1min, 30min or 60min. Alternatively, the analysis can be stopped at a fixed time.

Selection of results calculation

The results are calculated as losses or residuals with respect of weighing-in or pre-interval values (e.g. dry mass). The user may choose between %, ‰, g/kg, g.

All parameters are saved as individual methods on the prepASH.

Efficient daily analysis in just a few steps with prepASH

1st Step: Method selection and Weighing-in

Select the method for your analysis. Enter your ID (Name or Number) for your samples and crucibles via the touch screen, keyboard, or barcode reader. Place your crucibles (1 reference + up to 29 samples) into the turn table and start the automatic tare cycle. Then start your weighing-in procedure by putting the samples into the crucibles.

2nd Step: Unassisted / Standalone Analysis

After the weighing-in has been completed simply press the start button to start your analysis of the selected method. Now the prepASH has started it will continue to measure the crucibles until each sample has reached the auto-stop criteria. At the end of the analysis the prepASH will give an acoustic signal, switch off the heating system, cool down and open the lid.

3rd Step: Report output

The prepASH is printing out a report according GMP/GLP onto your connected USB or network printer. The report shows all process parameters together with weight curves and the result of each sample. PC software prepDATA helps for extended data evaluation, online monitoring, statistics and report preparation.

Important features:

• Fully automatic measurement of drying and ignition residue.
• Automatic compensation of the air buoyancy.
• Continuous weighing and storage of weight changes.
• Option to develop new methods with temperature and time profile. The system follows the specified profile precisely.
• The sample chamber is opened and closed automatically or by touching an icon.

Practical touch screen controls

• High-resolution graphics touch screen (colour, VGA 5.7″).
• Very simple, language-independent user guidance by icons.
• Process sequence with all parameters shown on the colour screen.

Perfect quality records with or without an additional PC

• Real-time display of the weight loss during the drying and ignition process.
• Error-free results recording by FDA/GLP guidelines.
• Display of up to 29 samples, individually or in groups (colored).
• PC software prepDATA for extended data evaluation, online monitoring, statistics and report preparation.
